[Q] Logic board issue - G2 Q&A, Help & Troubleshooting

Hi,
My G2 D802 screen started to behave strange (flickering, half white with dots) then became black, from the boot up, when i tap the screen it seems to respond (vibration, sound). I took it to LG service customer, at 1st they changed the screen but the problem persist so they told me that the screen connector is damaged and they don't have a logic board (motherboard) for my phone, they had only for 16gb version not the 32gb. I looked in the internet but i couldn't find where to buy one because i don't have warranty.
Do you please know from where i can order one or how to deal with this.
It's frustrating i only had the phone for 3 months
thank you

my touch shows only white screen

hay from today morning my htc touch shows a white screen and a crack on the bottom corner of the screen.i am sure that it dint fell down.
then what may be the problem?
anyone knows pls tell me...
white screen?
When you turn on your phone, there is no smart mobility.
Crack?
Is that an LCD problem?
i have the same problem with the WHITE SCREEN. bought my ELF 3450 second hand over the net. i am from the Philippines by the way and HTC units are not yet very common here and also the parts/accessories. it worked fine for about 3 months with minor problems such as Auto-Restart/Auto Power On/OFf which was solved using the "plastic on the OMAP chip method" - tnx for the forum for the info by the way and charging problems which was also solved by buying me a aftermarket charger. but recently the problem of AUTO OFF occurred again until it did not work at all. so, i tried to check the Plastic over my chip but to no avail the fone was dead. so, i decided to head to one of our local cellphone repair shops and have my OMAP heated thinking that maybe there are just contact points inside who became loose. when we tried to power on it was good for a few minutes then i noticed the screen went darker and darker and then it was all WHITE. we restarted it but it's just WHITE. tried to send messages and call it but there is no response from the fone. i'm afraid i toast it bad or may be it's just the LCD who got toasted, i am clueless.
CAN SOMEBODY PLEASE HELP ME WITHMY PROBLEM. CAN I GIVE LIFE BACK TO MY ELF? WHAT'S THE CHEAPEST & BEST SOLUTION TO THIS? THANX ...
Generally white screen problem are caused by defects in flex connecting the LCD to the mainboard or the connector itself. Try to disconnect and reconnect the LCD, if doesn't work - replace the LCD.

You warmed the OMAP? Interesting....
This problem sounds really complicated.
And im quite surprised of your 'warming' method.
I've had the exact same problem combined with the fact that my touch was resetting constantly. I was about a minute away from throwing it out of the window when I tried the plastic-piece-on-omap processor-technique described in one of the threads here. It solved the rebooting problem, but not the white screen issue. After a very frustrating couple of days where the screen started to blink and shake and then eventually turned to white alltogether, I lowered my brightness to the second stop from start, and since then I haven't experienced the white screen anymore. I believe it is heatrelated.
Whilst not being a full solution to the problem, at least it renders the phone usable.
Hope this helps anyone.
Heating the device very seldomly solves anything, but causes more problems that you originally started with.
iam using htc touch (p 3450) for nearly 18 months . (bought & using it in india ) my hand set fell two times in water and about 15 times fell on the floor (from shirt pocket) . still its working fine .
and iam using "opera mini " for browsing the internet . for some sites iam using "opera mobile " . when iam on opera mini , continueously for long ours , suddenly it turns white . never come to normal screen unless restarted . but it happens sometimes , may be because of memory or heating up of some H/W .
Hi hotchamo,
my htc touch elf hat a similary issue, and my father just "wringed" it gently until the white screen disappeared. You should try it carefully, since it may help and it won't harm. Just take in in both hands and turn them in the opposite direction, so that the case gets slightly twisted.
If that doesn't help you should open it and check the LCD flat cable connector...
Best regards,
scheutak
Again - flex connector problem. 'Wringing' it gently will eventually result in your LCD cracking, by all means - go for it, it will solve your white screen problem. Permanently.

[Q] Touch Screen from D800 on D802 hardware

Hello to everyone,
Dear friends, two weeks ago, by mistake as normally, I've broke the digitizer from my G2. I tried to take out just the digitizer but without success. So I have ordered an new screen&digitizer&middle frame in one assembly all together. Alone I have them installed, witch was a pretty easy job.
When the complete assembly has commed on it it was written "D800" and not "D802" as I was expecting. I have asked to the delivery company and they said that is the same. But after installation everything works well but only the drop down menu is not working. Also sometimes the touch screen become unresponseble. Sometimes I have to press 3 or 4 times till it activates.
I have read over the internet and people says that the top touch screen connector from D800 should be bigger than D802. This I could not see. Both of them ware the same. During the changing process, with the right tools, nothing became broken or something like this.
I have made also an hard reset but after that my touch screen becommed more hardly to use it.
What solutions do you see?
Thanks in advance for your time and support.

[Q] Warranty repair for black lines

Hello all, today I've noticed that my G2 has developed the infamous "black lines" accross the screen problem. I have black lines all over the screen vertically and horizontally. The lines appear to slighty flicker and they're constanly visible in all colors, but mostly in lighter colors. The phone is in a good state, few scratches here and there, dropped it once before (~0.5 ft height). The phone is around 10 months old and I use it intensely every day so I'd see if started happening after the drop, it didn't. My question is, does the warranty cover the screen replacement or adjustment (because I've read that it may happen because of the screen connector being loose) if it has the black lines problem? I don't want to open it myself and fiddle with the connectors because I don't have the skill required and I don't want to mess something up while it's still under warranty.
PS. Never unlocked/rooted/flashed, model D802
Thanks.

Warranty will cover it, when you contact them tell them you have tried all types of resets and factory restore.
They will issue you an RMA. Make sure you have the receipt of when you bought it, you will need to send it in with the phone.
I was going to send mine in for RMA but they wouldn't cover it under warranty because I bought it on EBay even though the actual phone was less than a year old.

Help, i broke/cracked screen

Hi everyone, I was wondering could someone help me out. I have a LG G2 which was stupidly dropped by myself today, so the top left hand side of the screen is cracked. half the screen don't work now so i can't even get into my phone with the passcode. I had a bit of screen burn on the screen anyway so it was going to get replaced soon anyway, also I can answer phone calls and the speaker seems fine.
Would this be the correct part that would fix all my problems?

I have the black version and was wondering would this phone look decent with a white front and black back casing, the seller also has the black version too.
Or would i be better off with this, with the casing?
eBay item number:
181465324464
any help much appreciated.
You will need the whole set. Since your touch isn't working. CALL LG for a quote. I believe they fix for about $100 including shipping.

LG G6 random screen flickering on top 3mm stripe

Hi All,
I've just bought a brand new LG G6 yesterday, and in the first 2 minutes a random, rainbowish 3mm stripe just started flickering on the top of the screen. The issue seems to be fully random, I could not identify the trigger nor reacts to phisycal strain. I also ran a quick LCD check which did not show any visible defects of the LCD panel.
Video about the issue: please search for "LG G6 random screen flickering issue" (since I am not allowed to post links yet)
Is this an already identified (or even solved) issue or is fully unique and I shall send it back immediately for replacement?
Thanks in advance for any help.
"Is this an already identified (or even solved) issue or is fully unique and I shall send it back immediately for replacement?"
No, YOU ARE SPECIAL Get the replacement.
