What can this be?? - Galaxy Tab S Q&A, Help & Troubleshooting

I've changed the LCD and the motherboard on my sm-t800.
Everything is working fine again except that i now have some kind of logo in the background. And also a line at the bottom and top. It's really weird. I have them all the time. I even flashed a new rom and it's still the same. Never had this problem with my previous motherboard or lcd. (Can't test out anymore because the both are broken. )Could it be that's it's something that's printed into the glass/lcd? And then the most imported question how can i get rid of it?
Please have a look at the photos and you'll see what i mean.

Looks like the screen has burn-in, did you buy it new because it looks used.

Yes i've bought it new. Because i've had a broken screen. So you also think it's the screen instead of the motherboard?

That is not new. That is almost certainly screen burn. Possibly from a demo model.

Ok thank you for the info. ?

[Q] Touch Pro 2 Screen calibration failed ?

Hi everybody,
I have problem with my HTC Touch Pro 2.
It was fully working until I damaged my LCD screen and digitizer.
So I ordered a new one LCD and digitizer from ebay. I changed old lcd and digitizer, booted up my HTC and everything looked allright. But problem came soon. Touch screen can't recognize my touch exactly. For example, if I click on something, digitizer solve it allways about 2-3mm higher. So I can't click on start, battery and every other click is moved about 2-3mm higher.
I made a calibration, but without any effect. I made a hard reset and than a calibration, problem still same.
And if try to make a new calibration (after first calibration after HR), I click on first cross (in the middle of screen), then up-left corner, down-left corner, down-right corner, up-right corner and nothing happens, I have to click on first cross again... and whole procedure again... So I have to make a HR and try to make a new calibration... still same problem.
Could anybody help me please? I'm going crazy, because I like my HTC and I can't use it anymore.
Is there any other way to make a calibration or how can I repair it?
ROM:
Energy.RHODIUM.29022.Sense2.5.Cookie.2.0.Jul.04.7z
(I have this ROM before I damaged LCD screen, any it worked fine)
It almost sounds like the screen/digitizer aren't lined up correctly... Just my .02.

Thanks for reply.
Ok, then It seems to be a HW problem between screen and digitizer?
So what can I do now? Try to repair it again?
How can I check, if digitizer is OK? or could be digitizer bad at all?

I'm just guessing from your description. I've never actually replaced the screen... If the two have to line up perfectly, I would ensure they are lined up correctly. Perhaps try slightly moving the digitizer down...

Ok, thanks. But I can't move with a digitizer, because it is in fixed position. Maybe I can move with a screen under a digitizer, but then I will not be able to see whole screen (digitizer has a black edge/margin/border).
Any other suggestion?

Nope, all I got. Calibration always works perfectly for me - if calibration doesn't work, there certainly must be some hardware problem. You replaced the screen, unfortunately you must establish where the hardware issue lies.
I don't have any help for you, sorry, just jumping on the wagon. My touch screen worked fine for a year but is now way off (1.5-2 inches sometimes) without having damaged the screen to my knowledge. I've switched roms (from MR.X to Mighty) and hard reset. If I try to calibrate it just keeps running through the process. Should I try to replace the digitizer? I plan on getting an iPhone if possible on Sprint in the coming month but would like to sell this for at least a little bit.
To both of you guys - have you ensured there's nothing between the screen or digitizer? Nothing that is wedged on the edge of the screen...?
I know some had reported complete screen failures just from some gunk that got wedged on the side of the screen.

Thought about that, but dismissed the tiny little amounts of gunk on the edge..currently searching for a toothpick or something small to clean out the edge. Thanks for the idea! Will report back.
Thanks so much arrrghhh! Found a small pin and got out most of the dust/gunk that was between one side of my phone. Apparently that bezel side is just a little bit looser. You saved me lots of time and money! Thanks. Always helpful on here and PPCGeeks.
Edit #2: Must still be more junk because the 100% functionality just went away. Time to clean it again

Are they really LCD screen or they are still amoled screen
Anyone tried to replace these LCD screen? how about their quality?
Wrong post... Please remove my message.
hi anyone tried
I think the descriptions are wrong. They should all be an OLED screen. I looked at a few of those and some say "OEM" or "Refurbished".. meaning they are the original unit but labeled as LCD is the wrong the decriptor for the type of sceen technology it really is.
Good luck.

Botched Attempt, WHAT TO look out for

Screen problem

Hi everybody I have a question regarding a screen problem I have.
Like I mentioned in an earlier post I accidentally spilt a lot of pure alcohol(the kind you use to disinfect a wound or something) on my HOX.
After a while the phone screen showed some strange grey shape on the lower right part of the screen and a bright white long shape looking like water jumping from a fountain on the left side starting from the bottom of the screen extending to almost the middle of the screen.After turning it off for 8-10 hours they grey shape dissapeared and the white remains and it doesnt look like it will ever go.
Strangely enough the HOX has no problem everything is working but I noticed that some apps are working somehow over the white shape covering it and some others like facebook seem to be under it making it visible.
I made some screen shots to show you the problem but stangely enough this white shape is not shown at all in the screen shots!!!!
Can anyone tell me where this thing might be?
LCD? Digitizer? elsewhere?
HTC funny enough suggested a factory reset to solve this and if that doesnt work(like there is a chance that it will...) to just send it to service.
I plan to play dumb to service hopping to fix this under my warranty as the phone has absolutely no scratch or anything anywhere as I never even dropped it once.
Do you think they can somehow find out what happened of maybe they will fix it under warranty?
Thanks a lot for your time reading this and I d love to have your opinions
Any photo?
Perhaps some alcohol got stuck between the lcd and glass...

Looks like overheating damage by a component beneath the screen, possibly something reacting to/affected by the alcohol.

When you say beneath the screen do you mean beneath the LCD as well or just beneath the glass?
I am just thinking that if its beneath the LCD it would probably not show plus the phone would have some kind of functional problem(it works just fine) wouldnt it?
Beneath the screen assembly. It looks like (possibly) some component or board has caused damage to or affected the digitizer, as your actual display seems ok.

So the service corrective action will be a screen assembly replacement or you think that something more will be needed?
Also if the digitizer was damaged wouldnt the phone use be affected?Cause the device has not been affected in anyway.
Everything works like it used to before this damage.
Send it of for repair, youll have to pay of course, how much tdo you like your phone?, that's the question.

I like my HOX very much otherwise why would I pay 428 euro to buy it?
Of course what makes the HOX stand out of the samrtphone crowd is the amazing display so of course I want it fixed.
I will try to cheat saying I know nothing about it(the phone doesnt even has a scratch) hoping waranty to cover this but if this doesnt work I ll have to pay 196 euro for screen replacement.
Although appart from that mark nothing else is affected I am worried that perhaps a screen replacement might not be enough if the digitizer is affected by something beneath it.
Do you think that a screen replacement will be enough to solve this problem?
HTC will give you the digitizer and LCD, especially if you end up paying, which will then get you a new bezel and unibody all still tapped up in protective coat, I've had it done for my phone, 160gbp.I even think you get the Onex+ version screen, gorilla glass 2.Could be wrong

Screen replacement tab s 10.5

So I just bought a tab s 10.5 on ebay with some pretty bad screen burn in and I'm trying a burn in fixer now but I'm thinking down the line I'll probably just replace the screen. I've looked at some videos of the process and I think I can pull it off myself but the videos all end before its completely taken apart. By that I mean the screens I see for sale have no brackets or connectors its just a screen with its chipset and a ribbon I think. The end of those take apart videos show a screen with a black tape thing in the middle and bracket all around. Is it easy to take off that bracket?
I can't post links or i'd post the video and a link to the replacement lcd but to sum it up, the end step of the take apart video and the lcd replacement look different and I'm wondering if anyone knows if its hard to move those parts over to the new lcd.
honestly, in my experience, burn in "fixers" are useless.. lol.. I had a 8.4 with burn in and got used to it. but what I would do if I were you if look for a broken tab s with good screen and swap parts. like on ebay find something like.. good lcd, but reboots.. or good lcd but doesn't turn on.. stuff like that.. you be amazed at the pricing you can get. I swapped a tab s 8.4 once and it was pretty easy. I would think its the same situation. where did you see the how to? ifixit?

It was on youtube from Mengtor. One deal for $172 that has all those connectors/brackets on the lcd. I'm guessing its not that hard to port over if I have to though. I'll keep a look out for broken tablets though that's a good idea, thanks.
Edit, ok there's a broken bronze colored one at $7.50 bid right now, any idea if the bronze panel will work with the white model? I don't care about the color mismatch as long as it all works ><

It should..
Having the part number for YOUR present screen and the part number for the one you want to purchase might help insure you get a correct replacement. I don't know how critical it is with Samsung but on my Asus TF700 it was very important else all might be reversed! One difference in a REVISION number can make the difference of a working tablet or not.

Failed to replace LCD Screen.. Help

Hello!
I bought a lcd screen (mine is with broken glass but working) for about 120usd from aliexpress and tried to replace by myself. I followed a tutorial step by step, removed Sim slot, opened the back, remove the screen and plugged the new one. I turned my phone on, everything was working (touch, image, fingerprint), but when I put the Sim slot back again, the screen turned to this (see attachment), and even after removing the Sim slot, the screen stays the same way. The old one is still working OK.
I don't know nothing about Eletronics, maybe could be these missing contacts (sponge metal) on the lcd from aliexpress? (the right one). Does it have solution?
THANKS!
:/
our phone has a super amoled screen...that surely is a downgrade, in screen quality and battery life wise. ;S
Either you got scammed, or some contacts aren't connected right. Try again
Are you saying that this screen isnt amoled? It's lcd? Thanks!
The exact same thing happened to me, including the color noise. I bought the screen from AliExpress. After asking someone with a bit more expertise than me, a was told that the displays actually are AMOLED, but they are inherently flawed cheap knockoffs using refurbished components and terrible driver chips, which only support 2 brightness values. My screen stopped working completely shortly after installation and didn't fit properly in the phone. A opted for a return and refund, got the $120 refunded and the postage fees only cost me about $15. I suggest you do the same. I got another second-hand P2 for $150 dollars with a screen intact and switched the screen from it.
Phantoml337 Thank you for the answer! Do you know if there is anything i can do to repair this screen or it wont work anymore? Thanks!

as long as you get an original display replacement or a good alternative, you can repair it as you normally would. Ask some experts, they know their stuff. Otherwise, buy a second hand p2, they often work just fine, flash some newer firmware on it, to make it clean and use it as normal, i guess.
But this fake screen, can I repair it?
