[Q] Nexus 1 Failing to Completely Turn On...

Over the last few weeks my completely stock (I've not even rooted it as yet) Nexus 1 has developed a behavior where, after some time, it fails to completely turn on.
During a normal turn on the screen comes alive, the hard icon buttons at the bottom light up, and the phone asks me to enter my unlock pattern. All is good.
Then, after turning it on several times in normal usage, pushing the power button will cause the hard icon buttons to light up, but the screen does not come on. The bottom icons will remain lighted and then go off in the same pattern that you'd see if you'd pressed the power button and the screen came on but you then didn't attempt to log in. After about 15 seconds the screen goes dark again. Pressing the power button for an extended period of time does not change the behavior with the bottom icons or the screen. With no screen I can't seem to do anything.
The "fix" has been to take the battery out for several seconds, and then put it back in. Then touching the power button will boot up the phone as normal.
Has anyone else seen this behavior? I cannot think of any software that installed that corresponded to when this behavior started. Taking the battery out for a few seconds is a consistent, if temporary, fix.
Again, its a stock phone:
AndroidOS 2.3.4
Baseband Version: 34.41.00.32U_5.08.00.04
Kernel Version: 2.6.35.7-59463-g52630a3

[Q] screen stays black

This problem existed on my Galaxy Tab GT-P1010 before but now it's to the point where the device is becoming unusable.
When the device is on and I click to power button to get it out of hibernation/sleep, the screen lights up but stays black and the power buttons light up. The device itself is on since I can unlock it and feel the haptic feedback when I click the home button or hear the audio change from the volume buttons but the screen stays black. I have to try several times before getting it on and sometimes it doesn't come on at all. This used to happen before but it would come on after a few swipes. The annoying thing is that when the screen does come on then it works like usual.
This problem has existed for a long time on this device since I got it as a gift, I've rooted it since then and tried several different settings but with no results.
I'm now assuming it's a hardware problem so is there any way I can open it up to fix it (plan to get another tablet anyways so not worth the repaid cost). Are there any apps I can mess around with to try to find a solution?

[Q] Black screen after lock

I've had my Nexus One for some time now, and i'm having a problem with it. Whenever i turn it on (sometimes i have to try more than once because it just stays black) it works ok, but when i lock it and try to unlock it (with the power button) the screen stays black. The action buttons at the bottom of the screen turn on but the screen stays black. I have CM 7.2 and i just flashed it and formatted all the partitions i could think of and it's still doing this.
If i call the phone after locking it, it will ring and the trackball flashes but the screen stays black.
Any help?
When the phone is on everything works fine.
P.S. I've searched the forums and found a few threads but none offer a good answer.
EDIT: If i leave it for like an hour or so i can turn the screen back on with the power button, but only once.
i have the same problem, am using the stock rom .. it happens after ending a phone call the screen stays black and i have to restart the device
waiting for solution !!

[Q] Lines on screen and black background

Hi all,
When I flash a kernel (bulletproof or elementalx) on my one, I get a black background and lots of horizontal lines along the lower third of the screen. However it becomes extremely hard to press buttons on the screen. For eg. If i hold the power button, the screen dims, but I can't actually see the options to power off, restart etc, but the buttons are there.
I've only tried the latest ARHD and MaximumsHD. The kernels were working fine on the previous (71?) ARHD and everything before that. How do I fix this?
Edit: I've now tested this with older versions of the above roms and I still get the horizontal lines and black backgrounds.

Need to flash the stock kernel or firmware. Since the issues started with the flash of a custom kernel.

Screen black, reboots but still black screen

Tab s2 8.
Was using practically fully charged tablet one minute, went to use again and screen black.
Back and task switch buttons still light up when press power or home. Plus volume up/down makes the louder/quieter beeps.
Power and volume down gives me the quickest flash of the samsung and android boot logos and then screen black again. Makes the email received notifications you get when restarting the tablet.
Is basically on but just no screen. But screen still functional enough to briefly show boot logos.
Any thoughts?
Update. After about 30 mins of faffing, magically returns to life. Any thoughts on common issues that might have caused? Indicator of something about to go wrong for good?
Put down gently today and the right side of the screen displaying flickering dark/black stripes. Left side of screen perfectly fine. Touch still works over the whole display. Any ideas? Internal cable come loose? Or something more terminal? How easy to check/fix?
