Television and Home Theater

Does anyone know why my tv won't turn on??? I have a 61' RCA Model D61W20, I "push the "ON" button and all I get is blinking green power light. It'll blink 3 times and stop. It used to come on after a few trys but now it won't come on at all...Any suggestions?!

I have a 65" diamond series from Mitsubishi WS-65908.  TV does not power on anymore.  I press the power button and it makes clicking sound but does not turn on.  I tried resetting TV by pressing the Menu and Input button but nothing happens.  The green light blinks and gives a code of 12 (Normal operation, no error detected).  Any help will be greatly appreciated.  I read couple other threads here and found that caps may need to be replaced on the DM board.  I need instructions on how to do that, if that is the problem.  Any docs with pictures wo

Im looking at buying a new HD Projector.  Do they work as good as advertised or are they junk?  I would think the glare coming in my windows would affect the picture.  Is the picture quality as good as advertised.
