Question about Mitsubishi VS-50603 50" Rear Projection Television

1 Answer

Damn TV....why doesn't it turn on when you push the power button??

When the power button is pushed the light will not turn on and you hear a click (only one click), but the screen stays black with no sound. You will also hear a click (just one again) when you push the power button again to turn off. Any suggestions????

I pushed the on and off button inside the tv set and i can't turn it on


Its a older set--if power light is green does it even attempt for a tiny moment to come on? Also let me know if at turn on you hear a very faint pop or hiss or even a buzz.

Tv clicks on and off. timmer light stays lite.


This could be a number of things, but first step might be: check that the power button on the TV is not stuck on, there could be a faulty push button or the button is stuck.

No picture or sound


Remove the rear panel. With the TV on you should see a red LED near the center of the PCB. There should also be 5 green leds, 3 to the left a 2 behind. If there is no red leds, check the fuses. If there are no green leds or maybe 1 or 2, disconect PSD5. It's a connector on the left side of the power board that connects to the audio board. It's the 3rd on fro the back. It's labled. With that disconected, turn on the set and look for the green leds. If all 5 light, the power supply is OK and you have a problem beyond that. If they don't all light you have a bad power supply.

TV Won'T Turn On


A fuse is not your problem. this TV has a safty feture that when it senses a problem it cuts the power to prevent any fouther damage, when you un plug it the TV resets and it will turn on agian. I have the same TV Check the CRT light guns there are 3 of them. If one goes bad it will cause your problem.
