    I have a 50'' plasma TV model PS50C91HD when I get up early about 4am to watch the sport, after switching it on it will switch itself off ( can be any length of time from 15 secs to 15 mins) then it will switch itself on, then off then on again every few seconds, it will keep doing this for at least on hour. then for no reason it will stay on and be ok for the rest of the day. Until the next day and the whole process will be the same.

    Please help.

    The TV turns itself off, then comes back on. Repeats 2 - 15 times then stays on.

It seems that the back light is malfunctioning or needs to be replaced the fact that it turns off after a few seconds indicates that is getting over heated. All LCDs, Plasmas and Projection TVs come with a shut off switch witch will turn of the monitor when a spike on the temperature is detected this is to protect the system from overheating. Now before you think about send it for repair; is it well ventilated? Does air circulates around it? Good luck!

The capitors on the back might be bad this I have fixed on these tv's many times. That could be one of the problems and the capitors are on the power board inside the tv.

Sony KDL-40V5100 Switches off by itself

Sorry to say but it sounds like your power supply is bad, although it is possible it is some other components in the TV because turning it off allows all diodes etc to power down completely. Unfortunately after a bit it happens again which leads me to believe again power trouble.

How do i manually get rid of the coloured lines on the side of my 40inch lcd samsung tv

Vertical colored lines indicate there is a problem with the unit. This could be caused by a bad T/Con board, main board, LVDS cable or the lcd panel itself. I had to replace a panel last week for this problem at a cost of around $800.00 since it was out of warranty. You can call 1-800-samsung to find the nearest service center.

Tv switches itself off then back on again


If the tv set is still under warantee get it sorted before gtee runs out.

The problem is caused by cummunication error between ATV Micom and DTV Micom.

To correct this problem requires going in to service mode to make changes & updating the DTV firmware.

This will need to be done by a proffesional.
