Backlight fails when warm
« on: June 09, 2019,12:47:58 »
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
