just tried,after i hit the power, the green light bulb lights up a while, and nothing shows up..........
This had happened to me a few times when I let the battery drain completely. Leave it plugged in for awhile before starting it.

did your phone flash on and off when plugged in?
My TP has CM7 alpha2 and WebOS 3.0.4 installed.
Everything seems fine, but after 4 days of keeping it away, I can't turn it on.
I try to plug in the charger, the home button LED is flashing, but it still cant boot.
Can anyone help please?
i have the same problem. after installing CM7 Alpha 2 on WebOS 3.0.4, my TP wont turn on and just stay at a screen with big battery indicator while charging.
I already hold POWER + CENTER BUTTON for 15 seconds and only the big battery indicator showed up.
Hope anyone could help me. thanks
Let it charge for a while then try to turn it on. Try power button only, if not home+power button for about 20 seconds but make sure to let it charge for a while.

Solved!
I let it charge for about 10 minutes, and the charging screen came up. After few minutes, I could turn it on.
Thanks!

Ur welcome.
Hit the thanks button if I helped.
How come when I power off and turn phone back on(no battery pull) and hold vol. Down, the phone boots instantly? If I turn the phone off and just press power and let it boot it takes about a minute to boot.

This happens to me on occasion just because im impatient. When u power off the phone even though the led light and screen goes blank it takes a minute to fully power off on its own without battery pulls or fastboot checked off. If you try to volume down power before it fully shuts down then thats when it boots back instantly. The reason is the phone hasn't fully powered off.
This is the fix. Or should I say "Completely Stupid Time Consuming Trick" that somehow fixes the problem(at least for me) because now my phone powers off and on normally. Here the Steps I've done. I tested this out 4 times and it worked all four times but it was only tested on my device. So this is not guaranteed to work and its time consuming.
Step 1: Plug in charger and let it sit there at the black screen for 7-10min
Step 2: Plug out charger and hold down power button until phone fully powers off
Step 3: Hold Volume up and down at the same time and plug in charger. It should be in download mode. Let it sit there for 7-10min.
Step 4: Repeat Step #2
Step 5: Plug in charger and wait about 20-30secs. :fingers-crossed: If all went well it should go to the battery charging icon or menu or whatever you want to call it. If it does, let it charge for about 5min and fully power it on.
Congrats your phone is now on and past the black screen. :good:
This will temporarily fix the black screen problem. Well... not fix but at least get past it and have your phone on. I suggest you never fully power off your phone and use power off and restart in power option instead of power off. To fully fix it do the following Steps:
Step 6: Power off phone by holding power button until power menu pops up, and by selecting power off. When phone is fully powered off, plug in charger and wait about 20-30secs and see if it goes to the battery charging icon or menu or whatever you want to call it. If it does then proceed to Step 7.
If it does not and just sits there at the black screen, you will have to complete Steps 1-5 to get you phone back on again and retry Step 6.:crying:
Step 7: Let it charge for about 5min and fully power it back on.
Step 8: Power off phone by holding power button until power menu pops up, and by selecting power off. Now power on phone again and see if it powers on WITHOUT THE CHARGER. If so proceed to Step 9.
Again,:crying: If it does not power on and just sits there at the black screen, you will have to complete Steps 1-5 to get you phone back on again and repeat Steps 6-8 again.
Step 9: Power off phone by holding power button until power menu pops up, and by selecting power off.
Step 10: Hold power button until phone flashes lg logo, then goes completely black(not the dim lighted black screen, COMPLETELY BLACK). As soon as it goes completely black, let go of the power button and wait for your phone to power on.
If you phone powers on it should be fully fixed and should power on and off normally(well at least for me). But AGAIN *sighs* If it does not power on and just sits there at the black screen, you will have to complete Steps 1-5 to get you phone back on and repeat Steps 6-10 AGAIN.
I recommend you just do Steps 1-5 to get your phone on and past the black screen. And to use power saving technique's to save battery when not in use of phone or when not near a charger. I may make an YouTube video on how this "Completely Stupid Time Consuming Trick" is done. But anyways this is what I did to fix the black screen issue. Let me know if Steps 1-5 at least gets your phone past the black screen and on. Steps 6-10 is pointless but worked for me but time consuming.
Problem fixed
disregard this post. read above post

I'm having a similar problem. But all I have done is rooted with RootOptimusG.bat and then used the freegee app from the play store to unlock. I then power off my phone and when i turn it back on all i get is the lg symbol and then a blank screen?
Re: Black Screen after LG logo
What was your fix, others may need it.

Hello,
I'm currently on Nocturnal Limited Edition rom. But this has been happening to all the roms Ive flashed to this phone. When i fully power off my phone or the battery fully dies, and i try to power it back on, the lg logo flashes then it just sits there on a black screen not turning on. I have to do this stupid little trick to get it back on(plus in the charger and let it sit at the black screen for 7min, hold power button and plug out charger until phone powers off, hold volume up and down then plug in charger and let it sit for 6min, hold power button and plug out charger until phone powers off, then plug back in charger and BAM mysteriously the phone powers on). Its frustrating doing this trick everytime i mistakenly power off or when the battery fully dies. Basically i have to keep my phone on all day with all these power save techniques i do. the only way i can actually restart my phone is by selecting power off and restart, rather than power off. My point is how do i fix this? how do i get it to boot up? i cant even get into bootloader because it wont power up. thanks in advance. :victory::victory:

Please post fix! I am having this exact same issue!
Edited first post
still cant get mine to restart. it sucks
I can get into download mode, after that it wont come back to life.
Any other help anybody can give me?
Thanks
I once upon a time have this kind of problem, solution below
What i did was remove the back panel, unscrew battery screws unplug battery & keep it unplugged for 1-2hrs or 5-6hrs. Then plug back battery with screws & back panel.
Its back to life !!!!!
I would suggest to take this to at&t replace & if outside usa this is the only possible solution for now.
Let me know if it works for anyone.
I tried the battery pull and it didnt work. Thanks for the idea.
Anybody have a fix for this or what causes this rediculous crap. Brand new phone and I went to shut off and reboot...now this

Did u keep it unplugged for "unplug battery & keep it unplugged for 1-2hrs or 5-6hrs" ?
This surely fixed, black screen.... any body else.
I used the lgnpst software and got mine to come back to live. Its charging now, it was dead. We will see tomorrow how it goes.
I'm working on that now. Downloaded files. Someone said we may need a special freegee app. Some phones don't take the reg app. Go figure

Well the first time I tried it it failed and got stuck in download mode, after many more tyies and a different computer it finally worked.
After it rebooted it said the battery was dead, so I had to have it on the charger for a while before it would start.
I hope itworks for you on the first try.
I was stuck on this screen after I flashed 2 back to back roms....I tried recovery mode download mode connected to usb to no avail.So I found this post.I let it charge on the black screen for 10 min unplugged it powered it down with volume down and power button and i held down volume up and power and it booted up with the animation for the 2nd Rom I used.Long Story Short battery was dead smh
I can't get mine into recovery, it won't work.

i have an evo v 3d through virgin. on my lunch break i went to use my phone and screen wouldnt come on. thought battey might be dead. when i plugged it in light would blink instead of staying on steady to show it was charging. wouldnt connect to comp. either. i thought it might be: battery so i put new battery in and let it charge overnight. The screen still dont work. It vibrates still and buttons on bottom of screen light up but the screen remains dark. I tried to do a reset by holding down the volume down button and holding the power button at the same time but that didn't work. any ideas on how to fix it would be greatly appreciated Thanks
Did the charging led ever stay solid or turn green?
Are you s off
Custom ROM / recovery?
Try taking your SD card out and then boot to bootloader, hold volume down and press power

with the new battery i can get the phone to charge. light is on when charging green when full and i can power up and guess where to swype to unlock. it rings to tell me i have new notifications but the whole time screen is dark just buttons at bottom light up. i tried holding volume down and powering on but that didnt do anything nor did taking out the mini sd card. no custom ROM or anything. should all be like was when i purchased phone new.
When you hold volume down and press power does the phone vibrate or do the lights on the cap buttons turn on?
I imagine your screen has died but I'm definitely no expert
