Hi, hopefully someone has some idea. I’ve got a panasonic tx-48cx490b.
When I first switch it on it’s great but after around 20-30 minutes the screen goes dark but the sound continues. Shining a light on the screen confirms the picture is still there but the backlight is off. Switching off and on will restart the backlight but it fails after only a few minutes unless it is left to cool down. With a white background there is one dark spot so I know I have one led out.
Anyone got any ideas?
Thanks
