Help my screen doesnt say its turning off

My screen will turn off like it goes black but this morning i looked at my phone and my screen on time was almost the exact same as the time my phone has been on. Let me be more clear. Last night i charged my phone and did a bump charge.(turned it off). Then i turned it on right before bed and put it on the table. I woke up and my phone was down to 40% battery and the screen times were almost identical. Any ideas what could cause this? Or a fix for this?

Advice Needed.. Touchscreen has stopped working, 10 minutes to boot...

Hi all, I've had my Desire since they 1st came out, so about a year and a half now.. Had the same rom on there for about 10 months..
Last night I was sat at my desk and the phone just slides out of my pocket onto the floor, no big deal and it's not a big drop at all, I pick it up and go to turn wifi off and the phone just turns itself off, I try turning it back on and it stays on the pink logo for ages.. about 5 minutes before it reaches the lock screen but I cannot go any further because the touchscreen is no longer working.
The charge light doesnt come on, the battery icon is red all the time and the big battery appears on the screen saying please plug in charger, if the charger isn't plugged in then the phone just turns itself off.. Battery is 100% full and I even charged it on my partners desire and also tried her battery but it's the same.
I can access the bootloader but I cannot select anything as when i press any button the screen just turns off, and when i press any button again it comes back on. The phone will stay running in bootloader mode from the battery for hours and hours so maybe this could help pinpoint where the issue is as when the phone is on the lock screen it claims the battery is dead when it clearly isn't.
The phone still has reception and even H is connected still but I can't do anything at all.
I'm hoping somebody will recognize these symptoms so I can perhaps buy the correct part to fix this.. I'm pretty sure the fault is not the screen.
I have the phone layed on my desk now, I've stripped everything away and just left the screen and board, attached battery.. Same issue.. Detached screen and plugged in charger with battery attached, no charging light..

Backlight glow charging

Stock, rooted, leaving he phone charging overnight.
Next morning (every morning) I notice the backlight is slightly glowing -- looks like the back light is on and the screen set to black. Not the LED alert signal, that's sometimes flashing sometimes not (depending on whether I have a message), but there's a soft glow. If you had any room light on you cannot see it.
This morning I used the on/off button to turn the screen on, then off -- glow vanished. So it's not always there, and not related to (just) having the USB cable plugged in (which it still was).
The phone does charge, it is not hot, there is nothing that I can see unusual in Better Battery Stats. Normal battery life (well, seems reasonable, better than my GS2, about 50% for my average day).
Can someone take a look after a normal charge in a completely dark room -- is your backlight on? Again -- LCD solid black, just a dark grey glow through it.
PS. I will check tonight -- I am not sure if it starts on or not, I only have noticed it now on several mornings in a row, and forget to look as it starts charging.
Weird. I never seen that happened to me. Mine is completely stock and rooted with Rogers.
Now I'm really confused. I was curious and woke up a few times to look.
First, on hooking it up - no glow.
Then only one of three times was there a glow, but it was there - same symptom, you bring up the screen with the power button, then put it back to sleep - gone.
I think it must be some app. It may relate to the calendar notifications, last night one went off in the middle of the night which is why I checked it.
I'll try to see if I can pin it down; it's more curiosity than anything else. The phone charges fine, and it's not bright enough to bother, and I suspect the backlight could run 24x7 and not burn out before I have 5 new phones. Just weird.

Backlight works but screen is black

I don't use my watch every day. A few days ago I picked up my 1st gen from the charger and the screen stayed black. If I touch the screen the backlight comes on, but the screen stays black. If I hold a finger on the screen it buzzes like it should when you change faces but stays black.
I've tried holding the button for about 3 minutes and rebooting. I let the battery run down over a couple of days and recharged. Nothing has changed the behavior. Maybe it's just dead.
This is already a refurb as I got a replacement for burn-in spots right at the end of my warranty. I wonder if replacements get a new warranty.
Ideas?
Try doing a factory reset. might resolve your problem.

No picture, led blinks and phone vibrates?

I replaced a cracked screen a few weeks ago. I didn't put the new screen in flush at the bottom, slight gap and as a result the new screen cracked from pressing pressure. The screen still worked but cracks got worse over time.
Also the screen would freeze now and again for a minute or so then back to working again.
Now the screen goes dead and the charging led blinks with cable in and the phone vibrates every 3 seconds or so in a permanent loop with charging cable in?
Any ideas what's damaged and if it's fixable?
