So my screen stopped working a few days ago. It went black slowly, from the edges towards the center.
I took it to a repair shop and after they've tried a few screens I have came to a conclusion that some other hardware is faulty, as the current screen is 1000% fine. (Digitizer is functional, and the backlight works because the panel is OT dark when viewed in a dark room.)
I think my flex cable is faulty. What do you think? In this state the phone's not worth more than 100 euros so i don't feel like throwing it away, a flex cable cant be more than 50 euros?
So let me know what do you think

If they tried a few other screens. Then I doubt it is the cable as the new screens would be using a different cable. IT very well could be the connector on the board. I would send it to LG to be sure.

The new screens have a flex cable that is a part of them. Check out the attached picture. The part circled in red is the connector on the "board" (or is there another board inside the phone?) i think is faulty.
EDIT: I've made a mistake, its not the one i circled, the lcd connector port is not next to the charging port. it must be on the left upper side if i recall from youtube videos

Yes that connects the a main board in the phone. I know the new screens have a flex cable but you never said if the screens worked or not.

I'm 1000% sure all screens are functional including the one on the phone right now, because:
When I bought the phone, the original screen was half dead (two vertical lines from top to bottom), so the seller put a new screen. However, it wasn't glued well and it was lifting a bit on the sides.
I went and got a brand new screen, used the phone for 2 days when it went completely black. The brand new screen went black. So i went to the store because i had warranty, and they've put the OLD (the not glued well) screen and it was black as well. And the other ones were black too. I think you see the logic here. It's definitely the connector on that board. Why else would ALL screens be black?

Agreed it seems to be the main board that is having the issue and at tha point you maybe better off buying a new phone as it will be cheaper to replace the g2 then getting a new board.

I dont think it is the board on the screen. Something is wrong with the board on the device that is messing up screens attached to it.

Im gonna go to a repair shop and ask them to put on the board i posted. If it doesn't fix then it's the main board you are refering to. In that case im selling the phone since the main board is like 100 dollars or more

had to replace my glass and digitizer, so i did. after i put my phone all back together i get this weird kind of issue with my lcd. when i startup the phone it looks just fine, but then its like a shade is pulled down most of the screen. it will change depending on the background. just sucks when the main issue is fixed, something else goes wrong. anyone have this problem or know how to fix it shoot me a line.
thanks

i tried to post pics but i am a noob and it wont let me. sorry
nevermind about not getting pictures. here they are.
Try reseating the display cable.
i had taken it all apart and back together again, and its still the same.
Did you try the old display? If the old one works, and this one doesn't, then this one is faulty.
it is the old display. it worked perfectly up until i replaced the glass and digitizer. even while my screen was cracked, i could use and see the phone just fine.
How did you get the glued down digitizer off? Did you start prying?
Oh, and you should have gotten an LCD/Digitizer combo.
i got it off by heating the edges carefully with a blowdryer and used the plastic guitar pick tool to remove the glass/digitizer from the lcd. it came off way smooth and easy.
i was thinking to myself i should have got the combo as well, but didn't have the extra 100$ now i totally regret not getting it. FACE PALM!!!

I looked again. You (somehow) broke the LCD. Look in the second photo at the top in the middle. See the dark spot?
If there is no physical damage, send it into HTC. You still might be under warranty.

That doesn't mean there is any visible physical damage. If he carefully replaced any void stickers, he should be fine.

that dark spot it just a piece of tape that is holding the generic screen protector on.
there is no more void sticker, and i purchased it from someone quite a while ago, not through a mobile service.
Hello, can somebody help me ?, One day my hd2 fall on the floor and my digitizer crash, after that phone works well i had only few cracks on the sreen, 2 months later my phone fall second time but only from low-altitude on the floor. and my lcd stop work phone only vibrate and boot sound works but the lcd is black.do you think is somethink wrong with lcd or with motherboard ??? thanks a lot
It is the LCD, it has stopped working. Your digitizer may have stopped working too but you have no way of knowing this though as the LCD is not working. You can get a replacemeant digitizer and LCD that are already connected to repaiar it with. Do a search or have a good look through the threads in the back pages here and you will find a good bit of threads on people that have done this and go to Youtube and have a search there as it is some great DIY videos on doing this on there.
my digitizer gone away in first crash i dissamble it and best place for buy is ebay ? everything here is CE china export D

Yeah ebay will probably be the best place to get replacement components. And just a tip the Euroupean HD2 and T-Mobile HD2 replacement digitzer and LCD combos will fitt in either version of the HD2. But the T-Mobile ones do not have to me soldered to the main board and the Euroupean ones do have to be soldered. Now I do not know if the connector on the ribbon of the T-Mobile ones will be able to plug in to the Eroupean ones as i do not know if they have the resiprocating connector on the main board of the Eroupean models.
i have european version(non-us) P/N 60H00295-00P with ribbon wich need soldering digitizer so i look on ebay.but still i have care about motherboard:/

Not true!
T-mobile touch is connected to LCD through small connector and European version HD2 touch have to be soldered to LCD, but BOTH versions of 'LCD+touch combo' are connected to M/B through connector, no soldering is needed at all!

You may just be right my friend, it does look as if they both have the connector for the Main board. The combos come with the LCD and the digitizer already together, so yes there is no need for soldering. I was under the impression it was not his way. I will do further checking into this later as I just pulled up like 10 different sites but none show a picture that is conclusive enough for me to say for sure but good catch there pvii.

More of that, cable and connectors have the same size and pin nimber, seems that they are interchangeable (LCM+digitizer assembly of course). Motherboards have the same size and shape too, NAND is the only difference I could observe.
Tonight I came home and turned on my phone just to find the screen is potentially broken.
Everything else works fine except the screen. Whenever I press the power button it gives me a black screen with a few lines on it. If I smack it a little then the lines change.
I'm wondering if it's just a lose ribbon cable or the screen is actually going bad.
I'd take it apart but I don't have the tools for it but if it's still as simple as that then tomorrow I'll just go buy a screw driver

OK 1st the LCD (and the digitiser incidentally) are not jaw & ribbon connectors but are pop connectors.
Look in the youtube i posted below.
I have had considerable experience digging around inside Desire Z's. In all honesty unless you dropped your phone its more than likely your LCD is fubared
Even if you did drop it its probably fubared ..... your starting to get the theme eh??
Whatever your LCD is probably fubared
However the good news is the Desire Z is the easiest phone I have ever dismantled/reassembled, as it is mostly held together by lots of high quality screws, so you don't need to take risks and get frustrated levering bits around to try and remove them.
Also LCDs are easily obtained and cheap.
Check this basic disassembly guide its the best i know.

This one below is stills only no vid, but it shows some small parts steps to in the above, defo 2nd best unless you want to remove small components
http://www.youtube.com/watch?v=SliyuYBvfic&list=PLEBB8603769CE1417&index=14
Oh yeah since you need to completely strip the Desire Z to replace LCD.
You may as well do something about that pesky weak hinge spring whilst you have it in bits.
This is a VERY worthwhile mod it takes 2 mins and transforms the keyboard hinge mechanism.
If you can't be bothered buying an upgraded spring (which is actually WELL WORTH IT) then you can just stretch the old spring and replace it to get a good result, just not as good as the upgraded spring.

Just be slow and careful, better it takes 2 hours to do a 10min job than 15mins and a busted smartphone component.
Hope this helps bro

hi, well, being the most unlucky person in the world, i too have had plenty of experiance dissmanteling the desire z. been through two phones, changed 2 digitizers, 2 LCDs, and now i have a broken flex ribbon cable (i know this for certain). i ordered the only one, as far as i can see, in the uk, which turned out to cause the phone to overheat when the screen was on. typical. sent it back, but the idiot sold the only other one he had to someone else when he knew i needed a replacement! sooo, without wanting to hijack this thread, does anyone know where i can source one it the uk? (the complete flex ribbon cable and hinge mechanism, as just the ribbon cable would be very tough to replace on its own without damaging something) many thanks..
I have a LG G2 VS-980. The top half of my screen was completely unresponsive to touch so I decided to open it up and take a look. The digitizer cable that sits on the glass has been peeled off. Is there any way I can replace this myself? It looks to be sitting on there with just glue.

I'm on same issue.
mine is the screen not responsive about half inch.
Take a look the attached.
I'm assuming this is hardware relative since this happens in recovery mode.

Yes, It's hardware. My first thought was do a factory reset, but no luck. I know there are several places online to get and new digitizer or digitizer plus LCD combo, both are sold with new ribbons already connected to the digitizer. I'm just trying to find if I can reconnect the ribbons myself without having to buy a $70 and up digitizer and LCD combo. It came loose completely by itself. I've never dropped the phone or mistreated it in any way, so I'm also worried if I buy a new digitizer then the same thing will happen again. I've contacted a few places that repair smart phones but they have no idea only just doing some research myself. So now I'm here looking for some professional help.
I bought it about 9 months ago on Craigslist. I'll never do *that* again.
After I got it home, I noticed that the screen looks as if it has been replaced. A tiny bit of glue in the upper corner. Oh well. It was working fine. Or so I thought.
A few weeks ago, I started getting these strange vertical lines through the entire display. I couldn't figure out any pattern to it (time of day, temperature, etc.) It would usually go away within a few minutes.
Then today, I hit the power button to bring it out of "sleep" mode, and the screen flickered a few times... and died. I tried to power it back on; no dice. I pulled the battery and tried powering it on; no luck.
I plugged it into an AC charger and at least I saw the battery icon. I powered it on, and the screen flickered and died again.
Is this a known error or a simple fix? Do you need more information?
Sounds like a dead display, not a real common problem but it happens. You can replace the display which is not a huge deal but my concern is the glue you mention. That may make it a bit of a challenge to repair. Depending on what type, how much and where glue was put.
How much would a new display cost if I replaced it myself? How do I know it's just the display, not the digitizer or something else, etc.?
Check Ebay. Ebay is usually loaded with replacement screens/lcds. If you do buy from there make sure it is a Sprint variant of the SG4. There are suttle differences on the inside between GS4s. The lcd is the part you'll need to replace if necessary. I would advise, taking the display off first to inspect what the previous owner had done. It's entirely possible that the lcd cable ribbon is loose or not seated properly to the board.
The display will be the outer glass, digitizer and LCD all in one package. You can try to replace parts separately, but trust me it is not worth it. The outer glass is glued down to the digitizer, that is a real pita to get apart clean without damaging what is left. Then if you do manage to get it apart it may not function as well or be as durable as originally because the outer glass no longer makes contact with the whole digitizer. Think of it like a single piece of wood vs a laminate like plywood.
Granted it may not be the display (there is always a possibility it could be something else -like aliens) but most likely it will be the display. I would think of it this way- try to replace the display, if that does not work you can resell the display you just bought and you might be out $20- well worth it in my opinion.
Thanks for the info. Looks like the glass/digitizer/LCD will run me about $100, so I'm not sure it's worth it.
Does anyone have the link handy for the Galaxy S4 drivers so that I can get what I need off the phone?

I've followed instructions to take the motherboard out and put it back in. Is it difficult to ge the display off? Is the LCD cable ribbon easy to find?
