The Hitachi goes on into standby mode on power up, I then use remote to start the Hitachi, the standby light goes green (start mode) & picture comes on in 3-4 seconds mormally.

I have 50 inches plasma Hitachi TV (ALiS 1080HD). As the TV was on, the screen stopped showing (no picture) and no sound could be listened as well, without any reason. The power light started flashing (on and off) so I turned the TV off from the power supply (as the remote control was not responding). Few seconds later when I turned the power supply back on for a moment I heard a sound (making me believe that the problem was fixed) but once again the power light started flashing with the same en

I can change the different sources using the remote control and when I come back to TV, the picture (white fuzz or blue screen) will flash for a moment, then it goes black.

I recently purchased a used Pioneer Pro150FD and was told it worked. Now that I have plugged it in, I get a clicking that the power is on, but there is nothing coming on the screen. I also see a small red light illuminating from within (through the back panel) when the power is switched on. I am using a "osiris" remote that came with it and the control says "PIONR" but the switch doesno't work. I have installed new batteries in the remote. Any thoughts?

My samsung 46 inch LCD also has the problem of no picture, but clear sound. I read all the posts about capacitor problems, and have gone so far as to take the back off and the power supply cover to look at the capacitors.

When I first power up the TV, it looks like it is lighting up, but after maybe 1/2 second of buzzing, the dim light goes off completely. Looking at it from the back with the cover off, you can see the
