So i've read through the stickies and havnt come across anything really substantial, tho I have seen a few other user posts about their G2 suddenly losing video.
That's the issue I'm having.
Here's a little history for you:
Customer brought this phone in to me, said it had water damage. Bought it off them to tinker with myself. I opened it up, and sure enough there were some water stains on the flex cable and the back of the LCD. I replaced both with brand new parts, and now the phone boots, but has only a black screen. It receives calls, touchscreen works, makes clicking noises, all that jazz.... just no video
I've pulled all the rf shields off the logic board to take a peek under them, and there is no water damage at all on any part of the logic board that I can see. LCD and flex cable (and midframe) are all brand new, and I'd really like to get it working!
Somehow I dont think HTC will be willing to warranty this for me (tho I have replaced everything that had water damage, so it should be undetectable as there weren't any water stickers in the phone for some reason)
Thanks in advance!
well, after taking a long google walk, I decided to contact the manufacturer of the LCD I bought and try having them replace it for me. hopefully that is the issue and not one of the chips on the main board or some other cable i missed.
If it IS a chip on the board, I'd love for someone to point it out for me so I can try a reflow. Dont wanna reflow the whole board cus it's still got the internal stickers and I dont wanna damage them in case I can finagle a warranty replacement out of HTC
so does anyone have any other ideas what may be behind this issue other than the LCD? I dont want to have to wait to send this LCD back and get a new one, especially if the LCD isnt the problem
I'm not 100% sure about HTC phones as I have not opened one up yet, so i'll speak with my experience with BB phones instead.
When I was in the process of replacing the LCD screen of a BB Storm, there were 2 different types of LCD screen for one device. Perhaps this could be the case? In the BB case, there was a part number followed by either a 001 or 002, neither of which were compatible with each other. My assumption is a driver issue with the main board.
It's a small and simple thing to overlook, especially if you have prior experience in doing things like this, but I thought it would be worth noting. I would compare the old damaged part with the replacement part and make sure the part numbers match up. If the replacement LCD is from China or Hong Kong, I would be weary about their quality.
Regards.
well I got it on ebay, but it was a California seller. as far as I've been able to determine from looking at listings, the LCD's for HTC Desire Z and G2 are identical. All the clips match up right, and all the ribbon cables looked identical to the one I pulled. I'll look into checking on this a little more in-depth tho so thanks for the info!
Hey Bro,
did you managed to fix your phone? I just changed LCD twice, but still the same it boots and all but no video on it... You can even call it, answer everything else works but the screen... Im thinking to change the FLEX RIBBON CABLE, but after reading your thread not sure if thats going to fix my problem. With my original screen I had no backlight on the LCD with the replacement I got backlight on the LCD again...
Any suggestions, ideas welcome!
I already managed to brake the display... it works 100%, but the crack is so visible,that i NEED to change it... i can't stand the crack from one side to another of the phone.
So, my question is, are there any spare parts for this phone, because it's only few weeks in stores, and if you can send me link or smth were can I buy and order online....
thx!
edit:
(digitizer/touch screen is broken, not display...)
LG P920
I was able to find a replacement glass screen on ebay for approximately £35. I have tried posting the link but the forum will not permit me to do so. Type LG P920 Digitizer into the ebay serach box.
If the LCD screen is broken then I am not sure as to where you can get a replacement due to the 3D nature of the screen.
How did your screen crack? Was it dropped or did it happen for no apparent reason? I have this same phone and the screen cracked while it was in my hand for no reason. I have only had it 3-4 weeks. I have heard of a few similar problems and their may be an issue with the quality of the glass that is being used.
I contacted LG about it and they just told me i must have dropped it and it was no concern of theirs.
I took it back to the shop i bought it and they have sent it off to be examined and hopefully it will be replaced free of charge. I am waiting to find out the results.
You may send it back to LG with a proper excuse or maybe a small fare to fix the screen.
Send it to a repair shop or......
Otherwise, you can grab some screens from ebay (OEM ONLY) and replace it yourself. *
*no further warranty method
I broke my D802 digitizer a while back and ended up ordering a whole new LCD/Digitizer set labelled "ePartSolution-OEM LG G2 D801 D802 LCD Display Touch Digitizer Screen Assembly Black Replacement Part" on Amazon (sorry, n00b so not allowed to post links). Now that it finally arrived, it seems that they sent me the wrong part - the top digitizer ribbon-cable's connector is larger than the socket on the flex cable board.
Does anyone know if it's possible to just replace the ribbon-cable part, eg with lg-g2-d800-charging-port-flex-cable-ribbon-with-earphone-jack per etradesupply.com rather than going through the hassle of getting a different screen all over again?
Thanks.
Had exactly same problem...
Anyone can say if we can just replace the ribbon?

Same thing just happened to me... *sigh*
Did either of you come up with a solution with the D800 screen replacement on your D802?
Or did you bite the bullet and order a D802 screen just because of that one connector?

I am in the situation that I have installed the D800 screen over an D802 hardware. I could not see the different size of the connectors, because it was not. But after installation the touch is not all the time responsive, and Drop Down menu is not working.
Have anyone tried to change that ribbon-cable part? Is working after that?

I'm also using the D800 screen on D802 device, but my top ribbon connector did not fit.
The screen displays everything fine with only the bottom connectors, and there is SOME touch input.
But because the top connector isn't in, touch input is not reliable. (With "Show touch" enabled in developer settings it shows the white touch area jumping all over the screen when I try to touch)
I'm currently only able to use the device with an OTG cable and a small USB wireless touchpad/keyboard.
with OTG & Mouse mine works too, but I intent to do not use it like that.
Is strange because before starting to replace the screen I compared the old connectors with the new ones and they ware matching. I was really surprised by the end when I realize that is not working. What should be different?
My screen replacement was 90 Euro, so I would spend another 30 for that Ribbon Cable Part if I would know that is the solution.

I wish I knew a solution too for the connector too, if theres is one...
Else maybe just bear with this way of interacting with the device and post a local online ad, to buy someone's bricked/non-functional D802 for cheap as long as the screen is intact. Then harvest it
This is what i'm doing, still just waiting.
Guys i have the same problem but i maybe found an solution.
The deal is the DOCK USB JACK flex cable. If you can notice on the pictures
the up side on the digitizer connector are to small on the D802 variant otherwise the
LS980 varian have the ''big'' up digitizer connector.
Now i have an issue on this flex cable of my LS980 and need an new one.
The thing here are that i also have an broken glass and the replacement for the D802 variant.
I sent the questions to a couple of Chinese sellers on ebay and lets see if
anyone have the knowledge to answer this question.
I will post any news...

Hi, I ordered a replacement lcd with touch inc. frame but my top touch/screen connector is too small for my board.
Sounds like I have what you need and you what I need. I'm in UK, if you are also and still have your replacement, swap?
Hi guys, any update about this?
Thanks !
Hello,
Any news about just replacing the flex cable ?
Thanks.
It seems that the longer flex connectors (for the digitizers) are for the LG G2 versions VS980 and LS980 which are Verizon and Sprint phones. Now remains the question if the main flex (like this http://www.ebay.com/itm/USB-Chargin...or-LG-VS980-/311384590958?hash=item487ff7ca6e )is changed will it work to place touch for VS980 in D802 phone?
I bought a D800 flex cable with a d800 screen and replaced my broken d802screen+usb flex cable.
The phone doesnt work properly after replacing those parts :/ It charges very slow ( 20% in 1 hour)
The Touchscreen doesnt really work, its just some random input when i touch it, you cant use the screen like this at all.
I guess theyre just not compatible...or perhaps my replacement screen is broken?
Lets assume its compatible, why would they go through the effort of making different screen/flex cables connector?

Hi, For all of you still in confusion lg g2 has 2 kinds of displays with different pins. d802 and D805 have different pins than every other g2. so if u have any other G2 (variszon att&t t mobile of korean) dont buy display for D802 and D805.
Hope it helps
I have LS980 and I also bought LCD for D802 by mistake. Next I bouhght the flex cable for D802 (with smaller connector) and put those parts in LS980. Phone is starting but display not working. So.... for those that are confused to buy flex cable... it's not working.

hey. if i understood you correctly, i'm in the reverse predicament. i have an 802 and bought the LCD with the longer connector. wanna trade?
Ran into this problem with my glass only repair for the g2.
Repaired the digitizer using LOCA got everything ready to reassemble only to find out the seller sent the wrong glass digitizer for the d802 vs the d801 I have.
Was so pissed off especially after all the screen issues I had in my formal thread.
You would think I'd confirm the flex before I began...go figure lol
Small price to pay for not confirming up front.
Moral of the story... d801's screens are not compatible with d802
I've ordered a used Galaxy S4 on Ebay and received a cheap clone that i'd never used has my own device. It's one from Mediatek and i was wondering if i can at least use it's lcd/digitizer with a legit S4 i337m because i have one with the screen broken so i would at least not be losing everything on this? If not i'll just ask for a full refund and send it back to the seller.
no you cant the flex cables wont even be the same and i mean flex clabes as they are two different cables when the original s4 only uses one that connects to the logic board. the digitizer es integrated into the lcd screen and the flex is connected directly to the lcd screen on the back. It would have been alot better if you would have bought an lcd display for you model. and if you dont know how to take it apart you could buy one with the bezel for your model number. They sold me an lcd screen for 400 pesos and i replaced the glass using uv glue and it works perfect. and was a cheap fix. maybe you have a friend with a dead logic board and working screen or cracked glass where the lcd digitizer still work you should ask around may be cheaper with money on hand

It depends on if the clone uses a digitizer with the same connections, but most likely not. You could open them up and check if the frames and connections are the same, but each model S4 has the digitizer connections in a slightly different place

Hi I have a D802 that i brought a while back from Aliexpress running awesome flashed cm13 all good, then i dropped it and the front glass cracked but touchscreen was still working. After a few days the touch response got worse i put it down to maybe all the pressing on the cracked glass was causing this, so I ordered a replacement screen+frame D802.
Heres my problem one of the screen connectors is too short - doesn't fit flush to the connector on the motherboard
Please see attached photos and the last screenshot photo is i think my problem - My screen is D800 screen and my motherboard a D802
So I might order a D800 Screen and Frame, but will that work? Im thinking yes as mine is currently
Has anyone else had this? i think the screens should be compatible :-0
I did force that small connector in booted the phone but no touch response so i think thats the connector for touch.
Then you bought the wrong lcd display

I brought the one that corresponded to my model number D802
I was only aware after the fact when fixing the screen that my phone has a D800 screen and D802 motherboard !
u bought the wrong lcd.. the connectors varies . the lcd u bought supports only for d800 801 f320 versions

Trust me...listen to these guys!
Been down this road before...search my G2 screen replacement thread if you want more details.
It's better to get the right one vs forcing it. You Definitely Don't Want To Break Your connectors
Guys I understand, Maybe your not getting me...... My D802 has a motherboard from a D802 and a D800 Screen !! - So i brought a D802 screen and it didnt fit
I brought the correct LCD and it didnt fit - My phone is D802 but the motherboard fits a D800 screen ? Ive been running D802 Roms on it for several months
On some roms id have to change the lcd model to JDP maybe this would yeild some answers ?
So to clarify I have a D802 and when i brought the D802 replacment screen etc the connector would not fit - So according to the last photo i posted my connector is from a D800 so im assuming my phone has a D802 insides and the connector and screen is D800.......
This is an easy fix.
Return the 802 screen your bought and buy the d800 screen.
Its the one with the longer connector which is what matches your old one
