Failed power supply for the backlight inverter circuits or failed inverter circuits. Do the visual inpsection for caps with leaking/bulging top/bottom seals, bad caps can look normal also.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Trying to replace lamp in HDTV and having trouble. Does not function correctly after putting in new bulb. Boots up and then visuals go black and the green power light keeps flashing. Help?

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

Screen black. Power light on unit flashes red slowly. Power light on switching adaptor power supply flashed green slowly.


Sounds like the battery might be low which would cause the red flashing light and dark screen. Let it charge for a little bit then try turning it on again. If it still does it with the power supply plugged in, make sure there isn't a lens cover on it, and switch modes or try getting into the menu to see if you can get anything to come up. If that still doesn't work then it sounds like there might be a problem with the camera.

Green light, black screens, no sound, needs new battery???


The alarm is just a coincidence i suspect, green light comes on and stays on probably not the battery at fault. It would be red.
If the green light goes out and screens just flash one of your screens are at fault or a loose ribbon connection.

Check L2 near the power switch on your DS mobo. That part usually get loosen or taken out when you drop your DS. And usually you can recover it when dismantling your DS.

My camera has a black screen even when is on


It does not look good.
Here are some problems which could be with this camera:
LCD broken or bad.
CCD problem.

Since you go have some light on the green light, then that appears to be a LCD problem. this can happen if the camera had an impact to cause the LCD to be damaged or disconnected in some way.
