Help My element flat screen has picture and sound when I turn it on. After 15 minutes of being on the screen will flicker then back to good then it will completely fade to black but sound will be good . I turn it off and back on and it works again . How do I fix this problem?

If it is a LCD TV, and there is a faint picture, it is probably the backlight or inverter board (probably the latter). This is a common problem (especially with PC monitors).
Do an internet search for your model and inverter, you may be able to replace it.
Make SURE you REMOVE the power lead before opening the set !!!!

I HAVE THE SAME PROBLEM. TV WAS FINE UNTIL A FEW MONTHS AGO. OF COURSE ITS OUT OF WARRANTY. FROM WHAT I HAVE READ, AND BEEN TOLD, IT IS THE POWER SUPPLY TO THE UNIT. IT IS DEFECTIVE, OR IT OVERHEATS AND TRIES TO SHUT DOWN. A LAW SUIT IS IN PROGRESS AGAINST WESTINGHOUSE TO RESOLVE THIS MATTER. KINDA REMINDS ME OF THE XBOX 360'S WHEN THEY CAME OUT. ALL YOU CAN DO IS TAKE IT IN FOR SERVICE. OR, YOU CAN KEEP TURNING IT ON AND OFF, LIKE I DO. I HAVE HAD THIS TV ON ALL NIGHT BEFORE WITH NO PROBLEMS. AS SOON AS I START CHANGING STATIONS, OUT IT GOES. GOOD LUCK. WESTINGHOUSE WILL NOT EVEN EMAIL ME. I HAVE TRIED SEVERAL TIMES TO CONTACT THEM. I HAVE HEARD FROM THE LAW FIRM IN CALIFORNIA THAT IS GOING AFTER THEM. GO ONLINE, AND JOIN THE CRUSADE.

The lower "Y Buffer" board is defective. Best repaired by a technician, or contact Phillips support for the part if you think you are able to replace a small circuit board on your own.
