I'm new here and wanted to ask you all if anyone knows why my TV might be losing its backlight.
This is what happens.
I'm watching TV and suddenly it just goes black. If I try to reboot my TV it won't show any backlight, but if I wait a couple of hours, the backlight works, but for a short time (5 to 15 minutes). The longer i leave it off, the longer it works.
Some pictures are attached.
The TV model is a LG 32LS5600.
First, check if the TV works when the backlight goes out. Light up the display and you'll see. If it works, then one of the leds has broken hot. Replace it.
