[Q] ink markings on th einside of my digitizer. Cleaning tip needed - Transformer TF300T Q&A, Help & Troubleshooting

I just replaced my broken digitizer with one from ebay. I noticed some ink markings on it, but assumed they where on the outside of the protective film. However when I pulled off the protective film I noticed that it's on the inside of the digitizer. (yes I have to disasemble it again.) :silly:
How shall I clean it. Can it be done without harming the digitizer? How sensitive is it on the inside of the glass?

With the lack of response I chose to use wipes and cleaning solution from a Dust-Aid kit for cleaning DSLR sensors. I believe the cleaning agent is heptan, but it doesn't say on the bottle, so I can't be sure.
Anyway. It worked well. Had to rub a bit to get the ink off, but with a little patients it rubbed off without leaving any residue. Now the only defect in the glass is a small scratch. (which may well be why there was ink markings there. Probably a production flaw and the reason I got the digitizer cheap on ebay. Anyway it won't bother me much. Certainly not enough to replace the glass again.

Sorry I didn't see the post earlier. The dig's surface is treated with some chemicals that makes it hard for inks to stick. I've tried permanent markings on it, but hydrogen peroxide would dissolve it completely. Plus HP leaves no residue. I've had the misfortune of being advised to use white vinegar on it, and surely enough, it removed the chemical coating, which does not really affect the touch function, except it makes the screen looks mangy. Hope some will learn from this.

[Q] Minor scratches on screen, will toothpaste help?

OK, so today I threw my Incredible (AMOLED if it matters at all) into my backpack and some keys in there scratched it a little bit. The scratches are not too deep, and you can't feel them or anything, so I was hoping there might be a way to fix it. I looked around a little bit and saw that toothpaste can help for getting scratches out of things like CD's and such. Has anyone tried this on their phone? I don't think anything bad would happen, but I don't really know...
Also, I know that I should have bought a screen protector, so please don't remind me about that.
'Getting scratches out' sounds like a bit of a oxymoron. You don't have something IN your screen, a scratch is more like a bit of surface screen missing.
I can't see why toothpaste would harm the screen. Just don't get the phone wet, turn it off, clean up afterwards, etc.
Really can't see how it would help either...
I have never heard of using toothpaste to fix scratches, but since the scratches are not to deep I try this product that has done wonders it is called apple sauce and was originally made to fix iPod scratches. Look it up on amazon.
If this helped please press the thanks button
Yes! It works well, rub it in tiny little circles starting in the center of the screen and working your way out. BUT BE CAREFUL. don't push hard ar all, and don't do the same part more than 2 or 3 little "circles" or you may destroy the screen. if you do it right though, it should work fine.

What do you mean "destroy the screen"? How easily can I accidentally do this? I don't want it to get worse!
They say you can do it on CD's it acts like a polish. I think it all depends on the surface of the screen and what kind of metirial it is made up of.
Good luck though!
Vaseline. lol
Yes, it will probably work since toothpaste is the same as a car polish in general

Mustard works better than toothpaste. It turns into glass when you use it to remove scratches on your phones screen. If you rub it on your face every night before going to bed you'll grow a proper manly beard too. Really, there's no limit to the things you can do with mustard with it's amazing properties.*
*All of the above is patently untrue in the same way that turning lead into gold is pure fiction. Toothpaste contains mild abrasives. Would you use sandpaper on your screen?

Nice! I tried the mustard, and it looks like it worked! My screen looks brand new! Also, I think I can already see stubble after just one night!!! The only problem is now my pillow is stained yellow...
Anyways, I thought that the toothpaste helped because of the slight abrasiveness of it...?
There are products here in the UK made under the Duraglit brand as Brasso and Silvo. These are metal polishes, but are also available as a cotton wad roll impregnated with the stuff. I do not know if they are sold in the USA, but there may be something similar from US manufacturers. As their name suggests they are made to clean and polish brassware and silverware.
It is a very fine abrasive suspension, but it also contains ammonia to remove any tarnish, and white spirit to act as a lubricant. They are quite good at removing scratches from watch glasses etc., by gently cutting into the surface, down to the level of the scratch.
On touch screen devices, the touch screen sensitive layer lives above the screen glass, but under a plastic protective layer. It will be this top layer that you have scratched. The product above or something similar may work, but check that the white spirit does not attack the protective plastic layer.
As mentioned above small, circular movements, a little at a time may work. If you cut through the protective layer, you are in trouble.

Nice to see people getting into the spirit of things Anyway, i hope you find a solution that works. I personally might be tempted to ask the manufacturer to replace the digitizer, as long as the cost wasn't too prohibitive. I tried changing one myself on an old phone and it didn't work out too well
Am not sure about what kind of display cover your phone has. But, if it's capacitive or IR and the top layer is glass, take it to the local wrist-watch merchant/repair center and they could fix it for you using H2SO4 and some filler.
Alternatively, you can have the top layer of the touch panel replaced.
And, next time, do use a screen protector. =D

I am not sure if toothpaste would help the screen scratches, its not a tooth scratch.. LMAO
Is it true that tooth paste works like sand paper on glass, does that mean that it contain something harder than glass? I don't have scratch just want to remove paint between my screen protector. Want to know if tooth paste actually micro scratch the glass.

Odd spot on MY Sensation with oily residue

The problem is interesting and has several characteristics.
First: First, there seems to be an oily surface on my sensation that persists even after cleaning it.
Second: The surface of the screen has formed an odd shape that is containing this oily surface. For example, the oily surface is in a oval shape, and outside of that oval shape it seems as though the oleophobic coating is still there which prevents it from getting dirty; it strangely acts as a barrier which keeps the oil within the oval.
After battling with this problem, I decided to go on a hunt on figuring out any remedy to the problem. I realized that the problem might be because the oleophobic coating has worn away. Or, something far more probable and unfortunate is that the windex that my brother used on both of our sensations to clean the screen a while ago might have caused some chemical reaction in causing this.
I decided to clean the screen with alcohol pads, eye glass cleaner, and even went on to use Rain X to fix it. All of these solutions lasted a day, and then the oval oily spot would come back.
It seems as though the screen has turned into an oil magnet where wiping it away won't do anything...at all. It's as though its trapped there until the use of alcohol pads or glass cleaner is applied with a micro fiber cloth. But again, after some use it just gets dirty again.
I finally figured out my cheapest solution would be to clean it with eye glass cleaner and apply a screen protector.
My concerns in buying a screen protector is that I need it to be clear without pixelating the screen (like Zagg) all while being able to use Swype effectively. any suggestions?
By the way, I found some others that had this problem but no solutions either: http://androidforums.com/samsung-galaxy-nexus/487288-odd-spot-my-screen-wont-come-off.html
EDIT: SORRY; Mod's can you please move this to Questions and Answers... sorry about the post.
The ammonia in the Windex was the most likely culprit in causing this problem. Unfortunately, once used on a screen with oleophobic coating there might be irreparable harm. The reason for this is because the glass has been bonded with the oleophobic coating and the ammonia works to destroy the finish and the polymers on the screen.
I am sorry that I can't offer you an suggestions on what screen protector to use, but there seems to be a thread indicating the ultra thin and, apparently ultra cheap, lcd screens are fine to use with this.
i just use a microfibre cloth to clean my screen, And my breath (its potent enough) And that works well for me
Try this http://forum.xda-developers.com/showthread.php?t=1164740 I have one, Fits perfectly you cant even notice its on if done correctly. Swype is just as responsive and no blurry image or nothing !!

Thanks. I am trying to find the same protectors without using a Paypal account (I don't have one, nor do I want one).
Are these the same ones from Amazon?

Tips for Digitizer Screen Replacement?

http://www.amazon.com/gp/aw/d/B00AHTFNEM
This is the one I bought, for a reference. I'm just curious if anyone else has done it and what problems they ran into. I'm no stranger to electronics, so I'm not afraid to take it apart, I'm just worried that I'm going to end up doing something wrong.
For example, the glass and digitizer are fused together, right?
And do you go around the front or the sides with the heat gun? 750w or 1300w?
Here's a good DIY video:
https://www.youtube.com/watch?v=_70-W9JjVjg&feature=youtube_gdata_player
A hair dryer should suffice so I don't think you need such a powerful heat gun.

I posted this thread a few days ago after replacing the digitizer myself. The video referred to by another member was for a phone, and personally I doubt a hairdryer would suffice for the job 'cause cell phones usually use light double-sided tape to hold the almost weightless glass. The tape on the Tab 2, on the other hand, is quite strong. You can use sheer force except there's no gap at the edge, front or back, and you might damage the LCD display in the process. I used a dryer for a few minutes and it did nothing to loosen the adhesive. Good luck.
That is an awesome tutorial. You're right about it giving confidence, as well as answering many of the questions I had. I guess I'm more concerned now over just various tips and tricks.
Is there any fine science to lining it up? How easily can it be fingerprinted and what would you use? Also, I've heard of WD-40 to remove the glue left over. What should I use if this one doesn't include any adhesive?
As you can see, I'm clearly a worrier. Got it honest.

Lining it up is a no-brainer since the glass fits snugly into the frame. The lcd is a non-issue since it is separated from the touchscreen. As far as finger prints,I use a 50/50 white vinegar/water solution. Be sure to wipe it off with a microfiber cloth while it's still wet. For left-over glue,I use either Goo-gone and 91% alcohol afterwards, or acetone. WD40 is fine though I am not sure it would not leave any residue after drying out. In case the new one has no adhesive, the better choice would be the outdoor double-sided tape for 5 lbs at Home Depot, or failing that, loctite outdoor epoxy though this one could get messy.

[Q] Can ''only'' the digitizer be replaced of a broken screen?

hi
i want to know if only the exterior glass of nexus 5 can be replaced. My phone has a cracked screen but the touch response, colors etc everything works fine so only the outer glass (gorilla glass?) is damaged. I want to know if only that can be replaced as LG ask around 150$ to replace the whole component.
can i order this? is this possible?
http://www.ebay.com/itm/C-Front-Out...-Google-Nexus-5-D820-D821-Tools-/171311153201
Thanks
Bump??
im pretty sure they are fused together and if you replace 1, you replace both.
Unfortunately you will have to replace the whole thing. When my screen broke It was functional completely aside from the proximity sensor (due to shattered glass). I tried taking it apart afterwards to no avail.
Well, you'll maybe be able to replace only the touch screen (without the LCD) but it wwill not be easy has you'll probably need to heat it to be able to remove the glue, etc.
Probably better to buy a lcd + touch screen :/
ohh
so the ebay item i linked is completely useless?
Thanks for your help guys
It's not impossible to try and replace only the glass. A friend of mine has done this with his galaxy note, which also has a glued screen+digitizer+glass assembly. However, the replacement glass is pretty bad and reflective and dust has started gathering beneath it. The touchscreen was also affected: some areas don't respond so well anymore.
I've replaced just the glass on a different phone. It's the biggest pain ever. You'd have to separate the glass via a heat gun, while trying not to break the digitizer. Then remove the glue. Then adhere the new glass to the digitizer with loca adhesive. Loca is hard to deal with, bubbles, and can get into other components ruining them. It must be cured with a uv light. And even if you can pull it off, no way will it be 100%. Strange glares and whatnot. Some try to do it with double sided tape, but that leaves a gap between the glass and digitizer, which causes strange touch responses or it'll be totally unresponsive. And be prone to break the glass easily without loca. Trust me pay the $150 and let lg replace the whole assembly.

It's too bad it's like this. Probably the most likely thing to break on a phone and they make it so difficult to fix and compared to the price of the phone, expensive to fix. Certain things should just be easily fixable. Oh well, such is life.

[Q] Digitizer replacement - glue replacement?

Hi all, I got an i9300, it has the digitizer broken and I need to replace it.
The problem is, here, in Venezuela, the UV glue and the UV lamps are too much expensive... due a pathetic government.
Anyways I need to fix the phone, and for that, I need to replace the digitizer but without the UV glue and UV lamps...
I know there is the double-sided tape but it leave a space between LCD and digitizer, so I don't like it, and... the tape is too expensive also.
I'm trying to find a cheap glue replacement, but I don't know if what I've found untill now would work or destroy my LCD...
So far, I've found a transparent glue, which has the following components:
1) Polyvinyl acetate.
2) Alcohols.
3) Special solvents.
It also says that it has no water.
The thing is that I don't know if this glue would be too abrasive with the LCD and may damage it in some way.
AFAIK, the LCDs has polyvinyl acetate on its components... but as I said, I don't know how this would react with the glue...
Somebody here can give me a hint? should I try it?...
When the glue I've found gets dry, just gets cristallized and over 60ºC it can be easyly removed.
I wouldnt mess with and unknown glue or adhesive that is not meant for this type o job. I would seriously recommend considering the double sided tape. Its a perfect fit and works perfectly.

I see, well finally, I've ruined the digitizer behind the pieces of glass... and the LCD with it, so, I must buy a new whole screen.
Warning: Do the replacement with extremely patience... do not pass the 200ºC and be extremely carefully.
