Panasonic tc-55cx400u backligjt issue
I have a Panasonic tc-55cx400u, and it will work perfectly for about an hour or so and then it goes completely blank. At first I thought it was going into sleep mode, however you can still hear sound and upon looking with a flashlight I can still see images being processed. When I turn the set off and back on, the Panasonic logo is there and the screen works fine for about 10 minutes then it goes blank again I am confused as to whether it is the LED strips or is it a capacitor issue or ? I was thinking if it were the LED strips the TV would stay out and it would not come right back up the minute I turn it off and turn it back on. I am wondering where should I start first....? Any thoughts on this would be greatly appreciate it, and thanks!
