I just got an MZ604 from my friend. He said the display stopped working and eventually sent it off to Motorola. They sent it right back claiming water damage in the following areas: 121009-002454 (cannot find out what that means). My friend does not remember any liquid getting on the Xoom. The unit was useless to him so he gave it to me and bought an iPad.
I brought it home and had it down to the frame and cleaned all contacts with CRC cleaner. I did notice a carmel colored liquid near the lcd connector, not in it, but on the wafer board to the bottom left of the CPU. There was also a small black mark on the lcd connector on the mobo. Obviously that indicates a short, but I did get the screen to come on, but the digitizer was not working.
Now the screen does not come on at all, but the unit powers up. The unit charges just fine and shows up on my PC when I plug in the USB cable. I was actually able to sbf to JB just off of the prompts in RSD. After getting an hdmi cable, I found the output to work properly and oddly the digitizer worked too. By watching the display on my monitor, I was able to tap the keys on the tablet screen until I got the wifi turned on and entered my wifi code. I was able to update from 4.1.1 to 4.1.2. Both cameras work as well as the speakers and the sd card slot.
My question is this, does it sound like the mobo, or the lcd that is the problem and is the hdmi tied into the lcd output of the mobo somehow? I cannot find a replacement mobo to save my life and I would gladly fork over $60 for an lcd, but I would be taking a shot in the dark. If I cant fix it, I will sell it as a whole unit for parts. The case/screen are in perfect shape.
Any input would be awesome.
I'm in for the unit if you sell it, i don't think it's just your lcd but the mobo
That's what I'm hoping its not. I troubleshoot until I am out of options. I think that point is near. I'll put up some pics.

I have a a spare lcd, trust me you can drop it in your bathtub without risk. All that could happen is corroded contacts
What is the going rate for "for parts" Xoom?
I am uploading pics right now.
The plastic is still on the screen since being returned from Motorola.

Sheesh, good question. A new at Amazon sells for about 300$ on ebay bids for a new are around half that, direct buy for 200. All parts are separately for sale new except the digitizer. What do you find reasonable?

Well i bought the TP2 digitizer and it has a hole in the front of it (whoops), Will this work fine with my sprint phone? Looks like the right size and same connector as other.
here is the discription from ebay item (It wont let me link the exact item) USA DIGITIZER SCREEN FOR HTC Touch Pro 2 2nd Gen T7373
I am planning on operating tonight and little worried, ( some people say ebay digitizers dont work well)
Also i need to disassemble to little bits or maybe just take the housing off the front (ive seen both ways on youtube and with out full disassemble looks hard.
Thanks for any input
lots of people look no one relies
Well took it all apart everything went great untill the f***ing digitizer and lcd would not come out i finally got it out and noticed tiny crack on the lcd part so looks like i need new lcd too.. I plugged lcd back in 2 ribbons back into mobo and plugged battery hit the power (it vibrates and turns on but nothing shows on lcd) Should it not show anything on lcd if everything isnt plugged in? (didnt bother plugging in the antenna plug the digitizer *(waiting for new lcd to plug that in) or the ear piece plug but i thought id at least be able to see the broken lcd light up. Am i wrong or did i mess more than the lcd up possibly?
I kinda expected to break the lcd when taking it out it was so hard.. another 25$ down drain but then again the lcd might have been cracked already not sure. I just hope it works with the new lcd. can i test the new lcd with it taken apart?
there is a guy on ebay selling a brand new replacement front for the TP2. it comes with
everything except the motherboard and back cover. i bought one from him for 70 and
took my motherboard and placed it in the new unit and used my old rear cover. works
like a charm and looks brand new.
well i see the gsm model for 25$ screen and all connected.. But since it seems like no one that repairs them replies (prob to old of a phone) I dont know if it will work, it looks like they all have same connectors so i dont see why the gsm screen would matter.. mIght take the chance and buy one those too to check it out, waiting on a new lcd to put back together to see if this one even works after my disassemble. (im guessing it will i didnt really damage anything but the lcd) 70 sounds like wya to much
yeah $70 was a bit much but it was basically a new TP2 minus the motherboard.
I don't know if the AT&T version will work with the sprint version tho. May want to
do a little more research on this before putting out that Dough.
Hello,
Touch screen glass was broken, due to my phone fallen on the ground. The LCD was still working perfectly so i've ordered a new genuine digitizer for my HTC Z710E.
After replacing it my GSM does nothing . When charging i see the charging light lighting up in red or either green when full, but besides that i won't do anything. I disassemblied the phone again twice, reconnect all the connectors and still nothing. Sometimes my phone vibrates and sometimes when i push the power button the charging light disappears but that are the only signs of living.
Is this a common failure after replacing the digitizer? Did i overlook something?
Hopefully you guys can help me out.
Thanks in advance!
If the LCD ribbon cable is, in fact, getting a good connection then I would probably lean towards the lcd itself having been damaged during the install. Due to the construction of the sensation, it can be difficult removing the lcd without damaging it even for an experienced tech like myself.
What I would suggest would be to go ahead and order a new lcd. This would also be a good time to double check that the part number on the new digitizer's ribbon cable matches that of the broken digitizer you removed, as the incorrect part will lag when the screen is turned on at best and will not work at all at worst. As far as I know, the sensation and kindle fire are the only devices like this where you will have slightly different parts even within the same model and region.

Hmm i already thought so . I did it really really careful, but despite that it broke.
Time for getting another phone. Don't have much money now, but i shall see what's for sale
So my photon Q is rather old. Shocking I'm sure. Recently the screen has started behaving very oddly. Flickers, sensitivity is weird, blacks out etc..
I thought perhaps flex ribbon due to keyboard sliding and closing but now I think may be digitizer or the lcd. I"m leaning towards digitizer becasue when it does work it looks perfectly clear. But there will be the one time i push the power to check if I have anything and nothing happens. Reset it and can see the screen wants to do something but can't decide what. Reset over and over and eventually boots up fine.
Digitizer?
Thanks for any info.
Anybody able to chime in
Flickering screen can't have anything to do with the digitizer. The digitizer is just there for input.
It could be that the connector is a bit loose on the mainboard. The way the Photon is designed I wouldn't think it's the ribbon. I could be, but very unlikely. Anyway it's worth looking into the connectors and just to be sure the ribbon as well. But that would take a full dismantle. The connector is just 5 minutes work.
Next time try booting into recovery. If that goes well (and regular boot not) i'm pretty sure it's a hardware problem (GPU).

When boot in any mode Ican't see anything.. A fading circle of grey lines runs vertically down the front. Sometimes after many reboots it fixes itself though. Good to know not digitizer. So take apart and check ribbon and maybe replace LCD likely?
I wonder if it is possible to simply replace the LCD if it's defective or if you have to replace the whole LCD-digitizer-speaker-etc set (which is expensive).

I ordered a replacement lcd screen so will find out. I also ordered the digitizer and flex cable.
So i'm thinking it may be more hardware involved than screen inolved. When it does work everything is usable and it works fine. This is only about 10% of the time at this point. Otherwise it boots up to show some vertical lines traveling down the middle of the screen but only in a circle in the middle of the screen that fades as it gets close to the edges. I'll try taking apart tomorrow night to see if ribbon and what not looks ok. But so far i've invested about $70 into parts and i'm thinkin about just snagging an S5 for $100. I will miss the keyboard though although I can hope that like the s3 and s4, the s5 will get a keyboard attachment. Thoughts?
If I remember correctly the LCD comes with the ribbon and camera connected. The digitizer is connected via a ribbon to a board in the top of the front panel. You could try to disable the pin. When the phone doesn't seem to work, reboot and try calling yourself. If it rings, there's something wrong with the screen and not the phone.
If there was something seriously wrong with the phone, it wouldn't boot. But that's just me guessing/assuming.
My daughter's Photon has had a digitzer replacement twice. And it looks like it's been used to play football. But that one still rocks. No quirks or any strange behavior for that matter.
What I'm trying to say is that the Photon is a decent piece of hardware. A family of four, we all have a Photon. Three of which have had their digitizer replaced and one an LCD (scratched it when replacing digitizer).
I swapped my Razr HD for an Z2. It was time for a new corporate phone. So that, and the camera, is the reason why I went for a Z2. My options were 930/G3/S5/Z2. S5 is not my cup of tea. The G3 has no ruggedness whatsoever. The 930, apart from WP maybe I should have went for it.
So it came down to the Z2. To be honest I'm looking to trade it when the Z3 compact arrives. We'll see.
@Loader009
Digitizer is a part, board for speaker is a part, the speaker itself is a part (adhesive, watch out, btw 100% the same as Droid4), and the LCD is a part on it's own.
Going to open up my phone tonight after work. I was bored and was just playing with the keyboard sliding it open and closed a bunch and now the screen looks perfectly clear.. although sometimes it will still black out and I have to reboot it a few times to get it back. I feel its more a connection inside like you stated earlier. I love my Photon and really don't want to have to get a non slider phone. New phone's are so friggin huge lol.
The good thing is, the PQ has gotten pretty cheap, so you might want to get a used one at ebay if the part to replace is too expensive.
flickering screen (backlight) is not lcd problem.
for 70% is it problem on mainboard - backlight ic. This problem is caused by using unoriginal charger.
and 30% flex problem
I had my screen become un-responsive etc, it was due to a crack in the ribbon. Swapped it out & all ok.
Easier to swap the whole screen assy than to change the ribbon, but depends on what spares you have/can get.
You'd need to have a good look at the ribbon for any damage.

I have a second generation Shield Tablet K1 that I purchased in December 2015.* The tablet was knocked off a counter and landed face down on travertine tile. The glass/digitizer did remarkably well considering but still had a large crack going down the middle of the screen. The tablet still worked in all regards* and I used it with no issues for 6 weeks. I purchased an NVIDIA SHIELD TABLET P1761W OEM LCD TOUCHSCREEN DIGITIZER on eBay.
I had the new digitizer installed locally at a phone/tablet repair shop. The shop called me and told me the tablet was ready for pickup but there were some issues with certain areas of touch screen not working. Basically the upper half of the touch screen works fine and the lower half does not work at all. As far as I can tell the area that works is exactly 50% of the screen. Just trying to do the basics on it right now is a pain as I have to rotate the tablet 180 degrees every few seconds in order to be able to touch a specific key or an app. Of course the shop won't warranty the work because I didn't buy the digitizer from them. What I'm wondering is if anyone can suggest a specific ribbon wire that may need to be replaced or simply checked to make sure the connection is good on it? Should I replace the touch screen controller?
Any suggestions will be much appreciated.
well, if you don't want to open it up yourself, maybe try getting another, more "able" person to look at it. Check reviews and the company, see if it's a known issue, it just might be a bad buy. I'm bet Ebay will do something about it if you contact them, also try contacting the supplier
I don't mind opening it up. I was hoping for some insight as to what to look for. I can swap out the Touchscreen Controller from my original digitizer and see if that corrects the issue. I thought with such a specific issue (only the upper half of the touchscreen working) someone could tell me yes, with that symptom you need to replace your Touchscreen Controller or that would only happen if XYZ ribbon weren't connected.
Maybe the touch screen is defect?
You're screwed. The repair shop tore the digitizer flex cable. The flex cable has no room to flex on an angle, so the cable just rips.
I just did this myself, and was looking around for a replacement when I found this thread. I couldn't find the problem until after I ripped it more; Now only the top left corner works.
I'm just buying a new one, because the problem I initially opened it to fix needs a heat gun, which I don't have.
Good luck
So a few weeks ago I was an idiot and crushed my OnePlus 8 in my trunk. I realized while I was closing it what was happening, so I was able to keep it from closing all the way and, surprisingly, the phone still works. Parts of the screen sometimes work and I was able to get a remote screen pulled up using adb and scrcpy. The phone still runs fine, cameras work, speakers work, battery life seems fine, etc. The big problem is that not only is the screen broken, it seems that I bent the frame a little too.
I don't have money to buy a brand new phone and I don't have any warranty so I'm in a position of needing to repair what I have. Does anyone have any suggestions for where I can get a new screen? Ideally I'd also like to buy a new frame so I don't have to try and bend my existing frame flat; I think it might break or the screen may not sit right if I don't do it perfectly. I've looked at a couple of places like Witrigs who actually sells a frame and screen assembly together, but I've read some bad stuff about them online and am afraid to go through with a purchase.
Also, I've noticed that OnePlus reduced the pricing on their in-house repair options recently so now it looks like it would be $160 + a $30 service charge so this might actually be the best option. I'm afraid though that once they get it they might have to replace the frame too and might charge a ton more or even decide to replace other components that aren't necessary.
The frame if distorted is probably toast. It's easier to replace both if they come as a unit.
If the service center it using OEM parts... go for it.
If you do it yourself follow full ESD protocols. The separate assemblies are very susceptible to ESD damage once out of circuit.

It depends on where you live. If you are from the USA, I recommend iFixScreens. They Provide free diagnosis of your phone, give you estimate charges, and provide 180 days warranty.
