Help G1 problem

Hi,
Recently I have been having a problem with my G1.
When I have left my phone on stanby for a period of time and I press the menu key to turn on the screen the screen back light comes up but it's blank.
I have to press the end key periodically to get the screen to come on. I have reflashed and wiped several times and tried different themes but it still does it.
I am running cyanogen 4.2.15.1 with the enoch theme updated via cyanogen updater.
It does not do this all the time it did it more with Darkstar.
I have been told I should re-root but I am worried about doing this because I am on the new radio and have been told I cannot flash back.
What to do???

G1 Black screen, Cannot get to bootloader

Hey, I have been given a phone off a friend to fix but it wont turn on. Booting normally, I get a vibration and then the backlight comes on but i cannot see anything. When i try to boot into the bootloader by holding the camera button and powering it on, the backlight comes on but nothing else. I cannot see the bootloader. Under both circumstances, I cannot turn the phone off. I have to pull the battery to turn it off.
Does anyone have any suggestions about a possible fix? Thanks

Havie you tried send when trying to enter bootloader? If it resets then you can still get to bootloader. If not, your friend has soft bricked and only way is to JTAG which takes strong hardware knowledge and steady hands.

ok im having the exact same problem. actually i thought it was a battery problem so i spent 77$ on a 3700 mAh new batter i guess tripple life... and got it yesterday booted gave same problems. black screen where T-Mobile should be yet the rom loads with scribble screen meaning u see part but it looks like the pixels are messed up. so actually decided to resort to what someone told me a Factory Reset so Pressing Camera + Power i got a Black Backlight screen yet wont show... and I cant turn it off without Taking out the Battery this has become a issue after installing cyanogen 5.0.7 T5... since then i Re-rom'd to superbad 1.2.5 same problem screen scribbles and stops im thinking did I fry it i dont even know how to google my problem because its pretty unique it isnt a battery issue its something in the hardware ... or am I wrong please send us some feedback... ill keep this thread in mind

Sorry, what do you mean by 'send'. I am a complete noob when it comes to G1's. I have worked out i can shut off the phone by holding call + menu + end but thats it. I still cannot see anything at all on the screen. I still only get a vibration on boot. How would I know if the boot has been sucessful but i simply cannot see?
Could the flex ribbon cable be nackered?

any ideas?

HELP Bell Vibrant Menu and back button glitch

I have a bell Vibrant. I was running on Darky's FW. But this happens on any firmware and even on recovery menu. As the phone is booting the touch buttons are illuminated, if I press one (menu or back) that light goes out and stays out and I can't press it anymore. (This also happens in CWM) When phone boots up both back lights are on and go off with the screen as they should. When I unlock to phone both lights come on and go out as they should. But if I press the menu button on the home screen, it opens the menu section and the light goes out upon button press but it sticks or something and keeps pressing the menu button on its own. I can leave my phone sitting on the home screen and the menu comes up and goes away in a continuous loop until I lock the phone. The same thing happens if I unlock the phone but press the back button. the light goes out after I press it and it stays out until I lock the phone again. So my phone can sit at the home screen but only one touch button is lit up? I'm sorry for the book I just wrote but I'm frustrated and can't figure out what to do. If someone has any ideas apart from sending it to Bell for repairs please help.
Thanks

Did you try flashing it back to stock JH2 or JL2 ?
does it work on stock ROMS ?

Yes I was on Darky's ROM, and when I got home I flashed back to JH2 like I have done in the past and it didn't fix anything. But I think the problem goes deeper than the ROM because even in Clockwork mod or during boot if I press one of the buttons the light goes out and stays out. I tried flashing back to JH2 and JK3 with odin. And Kies tells me I can upgrade current version even tho I flashed JH2 & JK3 from samsung-firmwares.

my suggetion, send the phone back for repair/exchange
and flash it back to stock ROM before you do
sounds like a HARDWARE defect

Weirdest thing. I left the phone off in my car when I went to work today and when I turned it back on it didn't do it anymore. But a couple of days ago this happened and fixed itself too and then happened again the next day.

Mine has done this intermittently since I upgraded to JL2 at the beginning of December. Doesn't matter what rom is running, it's still the same, even sometimes does it at the cwm recovery screen. It's annoying. :\

Mine does it too

there is a fix for this. I have the same problem, but I am running a custom rom and not sure if it can be flashed without going back to stock. Try this...

My I9000m stock with JL2 used to do that too. I installed speedmod k13c kernel and then darkys 9.3. That problem totally never appeared again.

Have you tried the reboot using the reset hole next to the SD card slot? Let me know if it works.

Have tried reset hole, as soon as you turn it back on it goes to the white screen, no dell logo or anything.

it is not death. if you factory reset it - it will work, but you lost everything you have in it.

So not to reveal my newbishness but how do I factory reset if I can't get into recovery mode ( holding down volume up and power button)? I'm totally fine with loosing everything honestly I only use the thing for light web surfing when my girlfriend has the laptop tied up. I appreciate all the help so far I still have 130 days left on my dell warranty but I really don't want to have to deal with them if I can fix this.

then first try fastboot, if it won't work, try nvflash.

Well, i kinda tossed this in my drawer and forgot about it for a few months, but recently found and thought i'd give it a try, nvflash and fastboot both do nothing, i'mat a loss here, i've searched around the net and found several people with the same problem but none seem to have found an answer yet. Any further thoughts or ideas would be appriciated.

Have you NVFlashed it with a HoneyStreak or ICS?

It was NVFlashed with honey streak at one point but it had been reset to stock froyo weeks before this happened.

wipe dalvik cache through ADB and flash honeystreak to it

White Screen of Death
I am having the same problem. I believe it is more a screen issue than a hardware issue. I had a light line across the screen for the last couple months, Wasn't always there, just sometimes. The other day I turn it on atthe screen stays white. If I tilt it, I can actually see some gray lines moving (vertical lines). I can tell the unit boots up, since it reacts to the touch. I can unlock the device (knowing where the unlock slider is on the screen).
I need some advice. Thinking I should buy a replacement screen on ebay. Bit of a bummer since I only paid $99 for my streak with T-Mob back in the day, so buying a screen for $70 and not knowing if it will fix the problem....I am a bit reluctant.
Anybody any ideas?
Thanks

I know this is old but i just got one of them in with the white screen and it is for sure a lcd problem not a boot problem.
