Need LCD part number! - Transformer TF300T Q&A, Help & Troubleshooting

Hi everyone
I broke the screen on my tablet over a year ago, had the screen replaced with a new one but when i got it back the touch didnt work. The guy seemed like he was sorry about it so he only ended up charging me 30 bucks and said something else is wrong. i was skeptical about it cause with the cracked screen the top corner still responded to touch and now nothing works
...long story short i did some research and saw that theres a few different types of screens for the 300 i figured they may have put the wrong one on so i removed the back to check the version number (it is written on the cable that goes from the glass to the tablet).
However. On my tablet there is no cable at all... i guess i got screwed by the place they put a defective screen or something... Either way of course the touch isnt working the cable isnt even there...
all i need to know is if theres another way to find the version number for the lcd they are pretty cheap online im just going to take a stab at fixing this myself..
ive asked asus that was a waste of time they advised me to send it in they would fix it for 250...ya right

Do you still need help with this? If you do, open the tab, take all necessary precautions with the battery, remove all boards and cables, and look where the digitizer's ribbons should be. If they're not there, it means they've been ripped when the "repairman" reassembled the thing. If the lcd still works, all you need is a new digitizer. A G01 would work across the board and is cheap. Go to this thread for more info. Good luck.

Thank you I had given up for a while but just wiped the dust off this thing yesterday...I'll give it a try

xda 11 screens

i have 2 spare xda 11 one is blocked and the other the screen is bugged up.
i want to change the screens so at least i have one phone working how do i fix or undo screen parts thanku someone please help dont want to buy another screen when i have 2 the same
Yo dude, the best thing to do would be to take the screen from the phone thats blocked n(coz no matter what, you'll never be able to use that phone anyway!!) and fix it into the one with the broken screen. If you do a search here, there are guides to taking apart an XDA II, and as long as you haven't got 10 thumbs, it should be fairly easy to do!!!
I've done this myself so I know it works, but the only thing you need to be wary of is there are two models of screen, just hope that both phones have the same model installed otherwise It could get a little more complicated!!

Replacing the screen
I am in a similar situation, I have an XDA2 with a broken screen and another one with a damaged bottom connector. I pulled them both apart to put the good screen into the one with a good mother board but to me the screen connector (the one that plug into the mother board) they look different. Just wondering if anybody has come across this. Cheers, Guito

Cracked Screen on my Touch Pro

I dropped my touch pro and cracked the screen in a few places. I think it works normally except for the screen, as it receives calls fine...
A new phone isn't in my budget right now. Does anyone know of a good place (hopefully in DC, MD or VA) that will supply or install a replacement touch screen?
(btw, no recent threads came up when I searched.)
Ebay!
Just looked, $30 including postage for a screen & digitiser if you are able to do it yourself.
How hard is it to replace a screen if it has surface damage? Is there anywhere i could find a walkthrough or help?
Shame man, its a tragedy of what happened to your phone...
Luckily its not too bad, and you may just be able to fix it. You can download the service manual for the phone here: http://htcwinmobile.blogspot.com/2009/03/htc-raphaeltouch-pro-service-manual.html
Just a note though, make sure you DO USE tweezers or something to get the speaker wires out of the way before snapping the enclosure back into position... I had to reopen the phone again, after powering it, to rejoin one of the little wires thats like a tenth of a millimeter thick DO NOT IGNORE ANYTHING THEY TELL YOU IN THE MANUAL. Oh, and what works well for the "plastic removal tool" is a cut out piece of plastic ice cream container. AGIAN, do not ignore anything in there... You are voiding the warranty permanently when you do it yourself (which you unfortunately have to).
Anyways, good luck!
I drop my phone also, but the screen didn't actually cracked! but I do have is problems with the screen in other ways! Sometimes I get a black screen when I turn on the phone and sometimes not, but when the screen turns on, it flickers a lot and have lines thru it. What suprises me is that sometimes I get perfect images on the screen (Which makes me think that the screen it's not damaged).
Any suggestion would be apreciated. Thanks!
3 days and still no answer from anyone! I would like someone to throw me ligth on this issue. I'm waiting for this to know exactly what I need to buy, before I start assuming things.
Thanks in advance!

Sounds like the LCD connector may have come unseated. You could open up the phone and make sure all connectors are firmly seated if you feel confident in your abilities.

Thanks for the advice! I was thinking on that also and wanted to take my chances opening the phone (oh god!).
BTW, I saw the $30 LCD Screen+Digitizer combo on ebay that Beeble referred to, but I'm not sure if it fits on the fuze (my model). What have come to my mind it's to buy also the front camera of the phone (like a thread on the kaiser) to mod the cell, in case I need to buy the screen+digitizer. I've search all threads about this issue but nobody has done it because it was too expensive for the result; I believe with this price it's worth it right now!
solved

I used Diamod (!) LCD and Touch Pro digitiser. Works perfect.
Much more cheaper
If your screen works fine sometimes, you most likely don't need to replace it. there's probably just a loose connection somewhere. If you really want to replace it though, there's an ebay seller with a really good deal. $20 for the screen and digitizer already glued into a new front body piece: http://cgi.ebay.com/OEM-HTC-FUZE-LC...wItemQQptZPDA_Accessories?hash=item3ef8817bf6 That one's for the fuze, but I think the seller has other models too. I'd definitely get the LCD and digitizer together or else you might end up like I did on my first attempt: http://forum.xda-developers.com/showthread.php?t=584050

WOW! What a long way to get to the screen. Good luck for everyone who tries to dismount and mount the Raphael.

Thanks for the advise maxh,
I just wanted to let you know that a miracle just happened! my cellphone started to work just fine without even opening the phone! it has more than a week on this situation so I believe that it's exactly what you stated (the LCD conector became unseated or loose). Since it's still working, I have no need to open it! so I'll just wait until it becomes defective again and at that point just open it and tight up the LCD connector!
Anyway, I would love if somebody could make the mod that I was refereing to before (changing the screen of the fuze by the touch pro one) and see if it's possible to attach the front camera on the fuze.
Once again, thanks everybody for your opinions.
I got my new display+ digitizer on Ebay (65$) and replaced it, using the russian link mentioned above ( follow the exact procedure) , it took me 2 hours to do it, and after lot of patience it worked! My problem was the digitizer never worked fine, and after replaced it it worked like never before. If You are not familiar with repairs, it will be a mistake and waste of money to buy a display without digitizer. NOW, I have a small problem, my display has a NEW color, it's like color temp is WARM for this display, and COLD for my old display, AND COLOR level is lower, and the result is display without vivid colors, black like gray. Is there any way to change the DISPLAY color settings?

[Q] Busted LCD got blue screen?

Okay strait to the point! I've got a Galaxy S2 with Android 4.0.3 bought it 4 months ago.
I accidently dropped my phone and cracked my screen on the bottom right corner. The crack went from bottom and a diagonal line up til the right side. I took a picture below.
imageshack(.)us/photo/my-images/685/20120326152703.jpg
This happened about 2 months ago. No problem since. I dropped the phone a few times afterward but it didnt seem to affect it lucky me.
Yesterday i tried watch some series over my WIFI and the phone got really hot around the camera area. The phone wasn't acting well either and then battery dropped from 75% til about 10% in 10 minutes without any video still showing up. (Never had that problem before). I stopped using it and instead put it on recharge for the next day. And today on the morning it was still okay. Went to school and back with the mobile still working. Put it on my table and checked my PC.
About 2 hours later while cheking up on my galaxy i discovered this.
imageshack(.)us/photo/my-images/198/20120326153629.jpg
I think that the LCD finally busted but i need to be sure if it has something to do with the previous crack and also if you could provide any info about what to do with it? Does my warrenty cover this? Or do i need extra insuranse?
I really need help right now LCD blackned spots
The screen has started to turn black from the core of the LCD leak. I now really think this is a broken LCD screen and not a software problem. If someone knows what i could do to fix this i really could need the help right now.
Someone correct me if I'm wrong,
But it sounds to me like you've busted the digitizer portion of your device. As to it being caused by the small crack on your screen.. i don't really know(can't really see if it's a crack in the glass or digi). At any rate, judging from the second picture you provided us it most definitely looks like you damaged the digitizer.
Most companies don't really cover damaged screens caused by users. However, being that your S2 is only 4 months old you could possibly pass it as "it did it by itself, I don't know what happen". Worth a shot I guess...
If all fails you could bring it to a electronics repair shop or you can repair it yourself via a digitizer part bought on ebay(probably pretty expensive being that its part of the screen)
If all else fails check ebay for a new screen.

If your thinking about taking the DIY road I found a screen for you.Quick note about buying something overseas on eBay: it usually takes awhile for the part to ship and even when you get it, the part may not be functional. But don't fret, eBay is usually pretty good about stuff like this so a working part will be guaranteed or your money back!
If you do decide to repair it yourself I would first research A LOT about your phone. Especially, the disassembly guide! Try to use only credible guides such as iFixit, repair universe etc.
This only applies to flex ribbon cables:
when replacing screens sometimes you have to plug it in a few times before you actually get it to respond(could be cause by oxidation of the pins) if thats the case, you could try to take a #2 pencil eraser and gently rub against the pins and remove the oxidation...
Good Luck!
Please let me know how it goes!

Yes it is really a crack and a very annoying one. It doesn't cause any problems with the touch-function, so I've been using it normally but for the screen, it has gone completely black but for the top right part still a little darkblue. I think I'm going with your first answer and try to check it in on warranty have had a bit luck with it past couple of times but im not sure about changing it myself. If having no luck with warranty then maybe ill try doing it myself.
at any rate weather you get warranty to change it or you fix it yourself maybe youll learn to be more careful and get a case maybe???

[Q] mt4gs wont turn on vibrates once

hello all looked every where seen similar ? but know answers any where .....have mt4gs that wont turn on just vibrates once was having problems with screen stuff looked distorted rainbow colored or screen not responding would have play with phone like slide keyboard in and out to get working again .....couldnt get to work pulled out battery put back in wouldnt start up.......same thing happen to the one before that similar prob still have it does same thing vibrates once........from what i gather from other posts is it might be flex cable have it apart flex cable looks fine ...would i be able to see if flex cable is messed up......... could it just be something came loose.......these are both factory oem no mods ...
If it's still under any kind of warranty I'd send it back with a note to quit returning the same phone to you. If you CAN send it, put a small indelible mark under the battery so you can check. If it's NOT covered you could theoretically fix it yourself if you're "electronics repair" inclined but it's not for the faint of heart....i.e., not easy.
If they try to SELL you another, you can get them on Ebay for half of what they'll try to sell you one for. For what they'll try to sell you one for, you can buy a Nexus 4 from google that's unlocked.....with enough change to take your GF out for a nice meal. A REALLY nice meal.
no warranty , not new to electronic repair or modding ....have two of these phone dont want to throw them out ..especially if it only needs and 18 dollar flex cable ...which would be cheaper than buying any used phone....... trying to find some info first so i dont waste money on flex cable for no reason ...ps phone is totally apart..........i think phone is turning on but nothing happens with screen and screen was buuging out when stopped working both times on both phones ..... any ideas thanx
Look at all the videos first.....

I just rebuilt my Slide (bought a new one that had a bad M/B on eBay for $65)--I tried to replace the digitizer & ended up breaking the LCD screen...The flex cable is between the LCD & the screen back mount....so it's not the easiest job.......Do yourself a favor & check out all the video on youtube first.
not a problem ..phones apart ...got skillz..... just looking for info ....i can take apart and put back together just about anything thats not the problem.ive done digi's ,broken screens,flex cables, power and volume buttons............ ive heard of this problem before just want to make sure i have the right solution ...so i dont buy the wrong part thank you
ps ...please no more posts about how hard it is.....
He does have a point, this phone is a pain in the ass compared to most, I too have disassembled many phones used to have a side business repair phones, and this was is possibly the biggest pain when it comes to how much sticky is used.
Anyway yeah it sounds like the main flex cable and that's where I would start.

So end result fixed first one....installed new main flex cable.....and tested it powered up and works fine just have to go back and screw her all together...was pain in the ass at the point where you need to separate lcd from slide housing but well worth will do another one tomorrow ....always first ones a ***** but not as hard as made to seem ......if any one needs help get at me will give pointers. will update again tomorrow
if any one has mt4gs and vibrates once and screen does not turn on its good bet its the main flex cable

p.s i have the htc mytouch 4g slide
There are multiple screen options for this phone, they all fit but aren't interchangeable, make sure your new one is made by the same company as old one

the phone was givin to me and i ordered the part on ebay it came from china. the package says. LH00042 LCD DISPLAY TOUCH SCREEN FOR MYTOUCH 4G. how would i know if it is the right part?
There are a few ways, usually the manufacturer is stickered on the back or product number. If you can't find this there is a line indented across the back of one and not the others

LG G2 questions

I picked up a used LG G2 from Ebay. The phone is in somewhat great shape and is functional except for the top portion of the digitizer. About an inch, give or take, at the top is unresponsive to touch. I just wanted some input on how common digitizer damage is on this phone. I know most phones these days are very delicate and the digitizers and LCD's can be damaged quite easily. There is a good knick at the top of the phone so I am guessing it had been dropped at one point.
I paid $150 for the phone and I can pick up the LCD, digitizer, and mid body assembly for $65 on Ebay. Just have to slap the internals in the new mid body, throw the back cover on, and done. Phone is good as new. But I don't want to make that investment IF by some chance the problem isn't the digitizer but rather something wonky with the main board. The more input the better. Thanks guys.
It's the digitizer, I sent mine in for the same thing.. Dunno how much it cost tho cause I had warranty. Hope it goes well replacing it

Thanks MaestriFC. While I was waiting on a response for this, I noticed the phone decide to go quirky on me. I looked it up and found on XDA this is a common problem? Phantom touches, etc.? I seen a couple people say it is still the LCD and digitizer causing these issues and replacing them fixed it.
Well I dropped my phone on tile with no case so I don't think it's a common issue (unless everyone is dropping them) but from what I read the digitizer was loose so you would have to open the phone and connect it, or get it serviced, I don't remember getting Phantom touches though..
Sent from my LG-D800 using XDA Free mobile app
Yeah. I read on another forum about it and found links to these problems here on XDA. Apparently, this phone going spaztic is a very common thing. Which still hasn't been traced down to any one specific thing. Most are having LG replace their phones just to get another one doing the very same things. I am going to order the new LCD and digitizer though. Hopefully it fixes the issues. Maybe LG got a batch of faulty digitizers or something....lol...here's to hoping.
Make sure you do your research on replacing haha wouldn't want anything else messed up... In my opinion you should just try to connect it properly and see if that works, that's if you're going to open it anyways of course, could save some money.. Good luck :thumbup:

I tried that. I opened it up, and from what I could tell the phone has never been opened. The screws were tight and came out with some black stuff on the threads. That's USUALLY a sign the phone has never been opened. I reseated the top and bottom connectors for the digitizer. The one on top and the one on bottom, I didn't reseat the other one at the bottom though. But I figured that one was for the bottom portion of the digitizer anyway. Which is working. When the phone starts up, every now and again, the "LG" screen will just flicker then boot up. But most times the "LG" screen shows as normal when booting up.
I did also find out from normal calling that the microphone for speaker phone isn't working properly. Normal headset works just fine. But when I switch it to speaker phone people can barely hear me. But that microphone costs like 8 bucks to change so no big deal. I have checked out many youtube vids on fixing this phone. It can be challenging to have to remove everything but I have found just buying the LCD and digitizer already mounted to a new mid body is the easiest way to go.
So the repeating the digitizer didn't work? I would buy the two together as it would be a lot easier than separating the two.. Might just be you had a faulty one after all
Sent from my LG-D800 using XDA Free mobile app
I haven't replaced it yet MaestriFC. I will report back in a couple weeks though when I do get the new screen in and get it all replaced. What didn't work was opening her up and re seating the cables. I thought maybe something could have been or come loose but that wasn't the case.
Just an update guys. I got the whole LCD and Digitizer replaced last night. It's only been a few hours but so far everything is great. No more glitching out. As a matter of fact, I had no choice but power the phone down last week. That's how bad the glitching out got. My phone was totally unusable. But now with the new screen, it's working great. If it stays working great then we can assume the problems with this phone are the cause of bad digitizers.
