[Q] Dead picture on screen

OK so I have a problem ... accidentally dropped this phone on the ground .. nothing serious like form 1m on wood floor and phone had small rubber back case, BUT now there is problem ... phone is responsive (android), touch screen works, but the picture is basically dead similar like from dead GPU on PCs.. I will provide you with a pic.
but the question is whats Wrong ? dead gpu or some wires ? and how expensive ?

May be its your display itself give it to Sony service center

I think your LCD has cracken itself, try to search is there are any cracks or something like that. However, you would need to change whole LCD with Digitzer as well, as far as LCD are not being seperating from digitizer. It would cost around ~70 - 80% of your phone price.

Prestigio multipad 8" split screen

Hello, i got for free Prestigio Multipad Thunder 8.0i 3G (PMT7787_3G_D), but screen is split, about half screen to one side of the cleavage is dead... But LCD is good, view is so clear and bright.
I try find out how change this model touch panel (she is from glass), but in russian forums i found just that to LCD with touch panel is full face glued and most people say that they spoils LCD when it try distinguish it from touch panel. Maybe something is to try to distinguish this model touch panel? I see in youtube some people separate LCD form touch panel with hot air fan-heater and strong fishing line, but some people in Russian forums says that the glue for this model is very hard (harder than Apple or Samsung). In internet china shops i see glass touch panels for this model in sale, it means that it is possible to change them, but how? Or for the new touch panel replacement match UV glues? Is this device worthwhile the risk to remove the touch panel and only buy touch panel (16$) , or if i failure to remove the touch panel and LCD will damaged simply forgetting that tablet pc, and maybe this device worth at once Buy the LCD with glued touch panel (60$)?
P.S. Many thanks for the answers in advance.
P.S.S. Sorry for my terrible english knowledge :/

I would say any device that you purchased for $60 is not worth repairing. If you do decide to repair it, then you'll need a heat gun which will cost you an extra $20 or so to buy. So you're going to pay at least $30 to repair a screen that might not survive the repair process.

I have people who lend for me good bosh heat gun, and i have good flat work table. I don't know where i can buy touch panel with glued lcd (ready to use LCD+touch) for best price, in aliexpress cheapest offers is out of stock... i write to services who repair touch screens, i got answer that cost me 30-50$ with parts and replacement, hmmm from they get screens :/ because i just find cheapest for 60$...
P.S. yes, this device is cheap now~100-150$ (i got for free) but it with Atom series intel procesor, is this procesor not a miracle? Good stereo, good 8" ips screen...

Z3c cracked screen replacement question

Hello everyone!
I recently cracked the screen on this phone. It dropped from my pocket on the parquet. After I took it i saw the one crack across the screen. The display is working but touch works only in small area. So I decided to look for a replacement. But I dont't want to buy the screen with frame, as service suggested me, because it is too pricey in my country. So I want to buy just screen.
And there is a question. Can I find original screen from Sony without frame (i read what it comes only with frame in assembly) or all distributors which sells just display module as original OEM Sony part tells lie?
And if I can't, is there any very good comparable or maybe the same in image quality to original display copy?

Hi. I'm owning small repair service and I can say from experience there is no original LCD without frame. Sony service has only whole sets with frame and speakers but sometimes without flaps. LCDs without frame are never original. Unfortunately there is no tested distributor who always sells good quality replacements. It's all made in China and if You buy one of those it's better to buy from local supplier because You can return it when low quality come out. When You order it from China, You can return only when LCD or touch is not working.

Thank You for the very informative response.

But anyway, if anyone has replaced the screen with copy and it is very good quality, please reply.

It is a lottery. So even if anyone has a very good quality copy, it doesn't mean that you would get (from the same seller) the same. Besides - the good quality would mean different things to different people.
I would buy either original LCD or a new phone. As much as I know, you can get later various problems with 3rd party screens. Besides visual quality the cable connections and built-in chip must be good also otherwise you can see mild to heavy distortions very soon.

If I had to change LCD in my own phone I'd take used but original part instead of new replacement.

I had bought SGS7 a month later but among 3 phones all was with different screen defects. So i decided to return it and wait for SGS8 and now repair my Z3c (I have to use my HTC One V for daily tasks - a dubious pleasure). I don't want to spend much money on this phone. In the case of display quality for me is the lack of differences with the original or if they are not critical (the image is comparable). I read the forums and some people really got good replacement.

Display replacement - with or without frame?

Hi, I got a small but deep scratch on my display, I think I got it from my beach holidays.
Before it'll brake completely, I wanted to order a new display on AliExpress.
There are several display, some cheaper, some not so cheap.
And some are declared as "original" but I don't think it's originally Huawei.
Anyway, most displays can be ordered in two versions, with and without frame.
The frame is the mounting area for all hardware parts.
Now I have a question to guys who already did a replacement or know the differences:
Is there any serious negative point when I order a display with frame?
In videos it looks much easier to replace the screen with frame but I don't know if there are any negatives, for example a not working finger print sensor (I know this from iPhones, because the sensor is married with the logic board).
As electrician I'm able to replace it but I'm not sure about the differences between the both display options.
Greetings,
Jannomag

it interest me as well

from my experience, as i bought for me, i had a nice surprise, for a OP5T, the glue was poor, and after just one month my display was flying, now i order just the display and use 3M, idk how indians are use the glue, because i can't never stick with that right

Proximity sensor always shows high (far) value after screen replacement

My Galaxy M21 phone's AMOLED screen got damaged due to liquid penetrating a few days ago. I went to the repair shop and asked to replace the screen with LCD one.
After replacement, everything is working fine, except for the proximity sensor. It always reports far proximity even if I bring a surface completely covering the screen. During calls, the screen does not automatically turn off when bringing it to my ear.
I have asked the repair person, and he replied that the LCD screen does not have holes to accommodate the sensor properly, so it is blocking the sensor. But AFAIK if that's the case, the sensor should always report near value, not far.
Is there any solution for this or is this a known problem due to LCD screen replacement?

Welcome to XDA
Not really if the mobo doesn't support the alien hardware.
The firmware instruction set may able to be altered to get the new hardware to work as you want.
It been better to use the original display, but not doing so you opened a can of worms.
Water damage? Possibility of mobo damage as well particularly if the battery wasn't quickly disconnected. If it was salt or brine water it's already dead.

By water damage, I meant a small amount of water somehow got into the screen and darkened the screen slowly starting from one side (a common thing on AMOLED displays).
I can assure that the water didn't cause any problem other than the screen, because I regularly check the device stats & sensors. The proximity sensor is behaving like this after screen replacement.

Well the former of what I said then applies.
I'm surprised it will even function with an LCD.

Sorry to barge in friend,
Thats why I am very careful with 3rd party repair vendors, I have lost many phones to them, they REPLACE new hardware with old spare components,its a bad habit they have & thats why the OEMs have "Authorized Service Centers" exactly for this reason.
For Shamshung devices I suggest you go to Shamshung Authorized Service Center only as Shamshung parts are quite in demand because of good build quality.
Small Story: Few days ago I went to Shamsung Service Center to try to downgrade my M21 from A13 to A11 (my phone is within warranty) & as expected they told me "only upgradable not downgradable sir!". I knew they were lying because a friendly shamshung service center guy once told me they do everything there internally, they have repair softwares there. Anyway, so I took the phone to a 3rd party repair station and the owner named Salman told me he has downgraded so many Shamshung phones of newer models, all I have to do is leave the phone with him for about 10 hours & he will downgrade from A13 to A12.5 then to A12 then to A11.5 and finally to A11 so it will take time, NO! he was lying! He was charging me a biggish amount but not just that he needed 10 hours to fix the mess that would happen when he stole & replaced the new components with older ones. Thats why Authorized Service Centers only friend.

@OldNoobOne I already went to Samsung's authorized service centre, but they only can replace the screen with AMOLED.
I was desperately trying to avoid AMOLED screens this time because they get damaged easily and are more fragile than LCDs (that's my experience with them).
Don't know how much correct I am, but I have seen most AMOLED screens getting damaged completely due to the slightest of shock or due to a single drop of water somehow seeping into it. I have never seen this type of problem with LCD screens.
Looks like I should have bought a phone with an LCD screen in the first place.

Yes friend, not just that LCD screen phones tend to consume lesser battery too. Another way to avoid AMOLED issue is that is to use a plastic pouch during rains etc. (there is no problem in communications) or also use a flip-cover instead of normal plastic/rubber back covers only. Just use a good quality scratch/screen guard like 3D+ and LCD will look quite like AMOLED

That makes perfect sense. Using an aftermarket LCD display does not.

All phones should be kept dry regardless of the IP rating. As you found out the AMOLED diodes used in displays are water soluble. The displays are sealed but if the seal is breached by water they will be destroyed in short order. Always use a good case to protect from impacts and high G loading induced damage when dropped. Wipe all water off immediately.
This N10+ in my has always been in a good case and unfortunately has been dropped onto concrete many times (zero visible damage). It has well over 8k hours on it. The display shows no sign of damage or degradation whatsoever. Don't use in direct sunlight and use manual brightness keeping the brightness at 50% preferably less it will get many years of service.

AMOLED displays use -less- battery, have infinite contrast (pure black) and the best color gamut. Higher and variable refresh rates are also possible, but these tend to use more power.
They are more expensive and have shorter, finite lifespans. Other than lifespan they are superior to backlight LCDs. That's assuming you protect the phone from drops and the design/QC was good when manufactured. Of course display quality can vary from manufacturer, model and individual displays. It could be you got a defective AMOLED display from the get go. Samsung's QC has been slipping in recent years it seems. A used N10+ in good condition might have been a better choice than a new midrange Samsung. It remains one of the best phones Samsung ever produced.
LCD displays are easier and cheaper to manufacture so you pay more for AMOLEDs.
If you prefer LCD displays by all means use them.
They are more rugged but not bulletproof by any means.
(Always protect LCDs from solvent exposure like isopropyl alcohol; they are open vented to the atmosphere and solvents can poison/destroy them.)
