The phone definitely boots up because the lights on the buttons flash on then turn off after some time. The keyboard also lights up. You can tell the backlight turns on on the screen, but there is no picture.
Anyone have any idea about what I should do? Thinking about trying to restore to a stock Tom somehow tonight. Then I'm thinking about looking for screen replacements.
I was curious if anyone has had this issue before.
Update 07/14/11
So I got the screen and switched the old one out for the new one. This one also only has the backlight turning on, but I noticed when I put a part back on, there was a little bump in the middle of the phone. Haven't had a chance to fix it, but I noticed it's a piece hitting this rubber piece that seems to "transport" the sound for the mic from the bottom of the phone to the actual microphone module within the phone.
Removed that rubber piece, and I'll try installing it later. I was getting some blue and red visible in the middle of the phone. Anyone know what's wrong?

ebay for the parts and look around for the link for repairs. I don't exactly remember the link, but it's in one of the "spring replacement" threads. Good luck

How sure are you it's the LCD screen? Replacement screens cost more than what I bought the phone for...lol
it's mostly the physical connection to the screen.
and on your note about it costing more than what you bought the phone for... there are tons of parts on the phone that will cost more than 30bucks. not much you can do about that since you got it non fully functional.

Sorry to be a both, but what exactly is the physical connection? Do I find it by opening the phone up completely to the point where I replace the actual LCD?

Never had to do it myself, but there is a cable connecting the two parts of the phone. That is usually where this problem originates from. It's not easy to fix though if your not familiar with fixing electronics from what i have seen.

I've taken apart my laptop completely and put it back together before. Completely as in taking the lcd off and different chips and wireless modules and stuff. I think it may be something I can handle. I'm going to take a look at it now. Restoring wont do me any good because not even the boot screen shows up.

So I completely tore apart the phone, got to the point where if I had another LCD screen, I could have easily switched it out. But I don't, so I just put it all back together. I really hope this new LCD will fix the issue. I really hope it's not some other motherboard issue. If all else fails, it goes up on eBay for $70-$100 as is for the phone. If I fix it, I just got myself a phone that goes for $200 used for only $57.
sure. goodluck with it. if you can do it then you're all set. good luck

Only $57? That would make the lcd screen $27 if u really paid $30 for the phone, but you said the screen was more than what u paid for the phone...so now im confused.

Sorry. After some searching on eBay, I found some sellers selling it for a few dollars less than 30, e.g. 27.
But I decided to go with a seller who sold more than 200, who claims the screen is an OEM screen, and who is top rated. He sells his for $32. Which makes my phone $62 after all is said and done.
The housing has some scratches on the top and bottom though, which decreases the value a bit, but hey, if it works I'll probably keep it as a backup. Currently have the HD2, but I got a Vibrant with original box and accessories for $100, so I think I'm going to sell the HD2.
That was kinda off topic, sorry
LCD screen should be here by the 13th.
Updated OP
someone help =|
I don't own a G2 but I still think this could be a similar issue to what we get over here on the HTC Droid Incredible. First, what makes you believe its still a screen issue if it lit but just didn't throw picture? Usually thats the symptom of having the wrong recovery version for the device hardware version. Normally for us what happens is we will get somebody who is new and rooting for the first time and they'll end up flashing the wrong recovery or freak out because they don't realize the root process takes a little while and yank the cord. End result being exactly what you've explained above. Phone starts but no screen. So we end up having them do the ruu or a second option which we call a "blind install" where you drop whatever your p file(ours is PB31IMG.zip) so whatever it is for the G2 drop that on the SD and reboot to hboot and do the update process by simply knowing how long to wait between key presses and what keys to hit without useing the screen. Its a unique process and all very magical. Haven't lost a single Inc yet because of this issue.
Anyways bud just a thought...

It doesn't seem to be a ROM issue.
Update 7/18: Sold the G2 on eBay and still made a good lump of money. I was very happy, until another G2 popped up with the same exact issue. Got it for a steal as well, and I tried the OEM screen I got from eBay, and it was still having issues, and it seems to cause the phone to overheat while charging. Definitely a defective screen and someones getting a great deal on a decent condition G2 because I already took the payment after I figured it was the screen I got.
I'm going to try to get a replacement from the guy that sold it to me on eBay, but I already left him positive feedback thinking it was the phone's fault.
Will update probably late July or early August when all of this gets sorted out.
TL;DR: bought 2nd g2 with same issue, turns out replacement screen didn't work in the 2nd g2, too late to not sell the first g2, getting another replacement screen to fix 2nd g2. First g2 was in better condition though =|
SWEEEEEEEEEEEEEEEEEEEEEEEEEEEET
Just installed the second screen that I ordered, and it works PERFECTLY. Phone is perfect nowwww yay. I can't use it right now though, previous owned put a lock pattern on the phone...
Wipe the system and the data and start over.

I recently dropped my HD2 and the screen popped, anyhow it has been replaced by the insurance company and the handset is immaculate.
At first I thought ahhh must be a new handset altogether but upon removing the battery and seeing the IMEI it's my phone or so I thought.
I powered it up and checked *#06# it's a different IMEI - should I be concerned? it may solve my heat issues I had on my old handset, only time will tell I guess. Bit narked that they tried to cover this up with the sticker from my old phone. Should I be bothere?
Something else that I'm not so fussed about, the screen on it doesn't have the dots when tilted in daylight (you know what I mean, capacitive dots) and it now has a blue tinge when off - looks a different type of screen.
Anyone come across this before any advice greatly appreciated
Normal, and they aren't covering anything up,,, they swapped out the mainboard, which gives you a new imei (new unlock code will be needed if its locked) but used your original casing with the sticker still attached.
Thanks never had to claim on the insurance before so wasn't sure how they operate.
I've had a bit of a play around and the heat issues seems worse! shut down after going on youtube app 20 secs into a vid...not good I fear

On stock OS?
Does this reboot/shutdown issue happen often with the new board?

I would get straight back onto them, repairs are often fixed using parts from returned items, (at least they are if HTC are like most other company) so its possible you got a defunct one.

erm what if I've put Artemis 62 on? Can I flash back to stock without them noticing?
for the past week my screen has been going whacked out on me.
the on-screen buttons would start clicking on their own, and sometimes the screen becomes unresponsive,
BUT
when i turn it off, and back on, it would work perfectly fine .
so i basically get a 50/50 chance if the screen going crazy on me...
now if it was the Digitizer, wouldnt the problem be ALL THE TIME?
as opposed to being random, could it be a BUG ?
Can anyone please help or advice, thanks !
If a factory reset doesn't fix it it is probably hardware. I have seen intermittent problems with digitizers before.

I have a similar-sounding issue (on-screen buttons flashing wildly, et al.); I am thinking of opening the device to check on connection
Is it more or less likely, in your experience, that the connection between the display assembly and the board is loose from impact or whatever, or that the digitizer itself is just defective?
Thanks for your help.
I had the exact same problem on my device and it can be due to two reasons.
1. If your phone get extremely hot during use then the screen starts behaving abnormally.
2. If you had dropped your phone then there is a slight chance that you have damaged the digitizer.
I had the second problem and I have replaced the screen and it is working normally again.
I bought a friend of mine a LG G2 and within a couple weeks she managed to have it take a drink. The horror on my face was, well, horrifying when i was told. Anyways about the phone.........
She knew to immediately put the phone in rice which she did.a few days later i get the phone into my hands, moment of truth right? First thing i did was to take it apart and see if there's any corrosion on the board or any leftover residue which i found none. reassembled the device and plugged it in for........well i dont know why, i just did. I read online if the phone shuts off immediately after contact with water your chances are good. Anyways the phone showed signs of life. It began booting up past the LG logo to the boot animation of "Desolation ROM" where it freezes and than loops freezing at different times of the boot logo.
Download mode works so i decided to flash the KDZ 20C. The phone boots up entirely into the OS and works with few *issues. Two things i have problems with, the internal storage doesnt appear** on the computer regularly, and i must "adb reboot recovery" a few times before it successfully will boot into recovery. but i can manage with that. I rooted it through sideload, installed autoRec and got TWRP flashed and working. I did flash the new TWRP so that it mounts the storage to computer. anyways so i went to flash the rom, Desolation, Resurrection Remix, and Bliss pop with the same issues. ive dont everything multiple times already to no avail.
Ideas? anyone?
*issues: it thinks the headphone are plugged it and rapidly cycles the animation.
** it varies from one flash of the KDZ to the other i can "adb Push file /sdcard/"
Solution: buy her an old Nokia

From my experience over the years water damage is a 50/50 shot.
On one hand you get a 100% recovered device with minor repair...i.e replace battery and or LCD and you're good to go.
On another hand you have weird malfunctions i.e headphone jack saying its plugged in when its not....dead wifi, dead vibrate, no data connection...the list can go on and on...
When this happens, unless you're skilled to replace the ICs on the logic board with some skillful soldering, I'd pass and either sell or use the phone for parts.
Start fresh with another used G2....maybe one with a broken screen you can get cheap and swap parts over to your phone.
Oh yeah...have your friend buy herself an S6 Active...

Have seen a few logic boards in ebay sell cheap the last 2 weeks. You may get lucky and replace the board with a newer/better condition one and fix your problem entirely.

I'd inspect the LCD and light box underneath to be safe as well.
If both look like new you're safe there.
Basically:
New logic board
New battery
New screen (if necessary )and youre good to go

Recently I've rooted my phone, one week later I was experiencing battery problems, drop 30% to 3%, unexpected shutdowns, camera and flash almost not working.
The flash doesn't work, only turns on one led and the. Shuts down, sometimes both but then shutdown instantly, he camera (when bat is lower than 30%) looks like a CRT TV
I've flashed the stock rom xt1644, and still having the same problems.

Ok, but only rooting the phone won't cause such behavior. I know iPhones, Nokia, Blackberry etc. with similar problems and after opening that, the moisture indicators were red or metal/parts was corroded,that's why I'm asking. Even dropping a phone can bring problems weeks later (iPhone 4 sound chip, wasn't soldered good). And as it seems you're the only one around here with this problem, I guess it's a hardware failure. (sorry for the story )
For understanding: you only root the phone to, nothing else(flashing something)

Was your phone new and the package sealed?
Is it only when the battery runs low? Mine did the thing with dropping from like %80 down to 30 then shut down and would turn back on at be like 44. If I used camera it shut the off off and sometimes calls too. I was told to try calibrations and resets and didn't help. Turns out I had to get the battery replaced by moto.

Had this same exact problem with this same exact model of the G4 plus on the stock rom (unrooted). I sent it in for a warranty repair and it came back to me with the same issue. I ended up doing a warranty exchange where you put down a deposit and they send you a new phone and release the deposit back to you when they receive the defective device back. I don't think you would be able to swap the device if you unlocked the bootloader and rooted the device since that voids the warranty but I can confirm that this is most definitely a defective hardware issue you are experiencing.

Ok... So this problem can also be present before you do flashing. Imagine the guy did what I think(dropped it, moisture, bad hardware cause lenovo manufacture it on a Monday), he recognized it, then sell it maybe with bootloader locking and you're happy who bought it now. That's possible!

I'm just curious, did you root using SuperSU? If so, which version did you use? I ask you this because you keep saying that all these issues propped up AFTER you rooted your device.
Battery charge jumps can be caused because of battery calibration issues, which you can recalibrate using a plethora of apps available (by using root access), or the old fashioned way.
I didn't respond till now because of your camera issues — CRT stumped me.
