Television and Home Theater

Hello I have a 42" Fujitsu pds4209u-b that i was watching and the screen went black turned it off waited about 30 minutes turned back on and worked fine for 5 mintues then turned it off and waited another 30 minutes turned it back on and it worked fine for 2 minutes is still acting the same.

The problem I have is when I put the IBM LENOVO PC which has windows 7 ON TO THE 32" lcd and on to the multimedia monitor the picture is blured when I put the hp pc which as vista on the pc on to the lcd and multimedia monitor picture is clear and sharp.

On the IBM PC I have a viewsonic 22" monitor and picture nice and clear, so could some one please tell me what the problem could be

I tryed different settings and still the problem was there the windows 7 I have is 1680 + 1050 as the vista is 1024+768 tryed the windows 7 on 1024+650 and still the same problem

I picked up this TV for $10 with the blinking light problem. The guy told me it worked perfectly a few months ago, but then it started taking longer and longer to turn on and now it does nothing but blink the timer light. The reset button stops the light from blinking until I release it, then it starts blinking nonstop again. I have it open and the DM module is out and I was surprised to see the capacitors on it are not bulged at all, though they could still be bad but I have no way to test them. I went ahead and ordered a capacitor kit just to be sure.
