LG 32LS5600 backlight issue

Hello everyone!

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.

LG 42 LB 650 háttérhiba
Üdvözletem!
A jelenség a megszokott, nincs háttérvilágítás, tápot kap, majd elveszi a táp a háttértől a feszültséget. Szétszedve a kijelzőt számomra elég furcsa módon a ledeket zárlatosnak mérem. Ha csak külön  csíkokra mérek rá azok is zárlatosak. Tudom ez így nem lehet, de hiába próbálom tápról hajtani külön-külön a ledeket az sem sikerül. Vmi ötlet? 131202 / A ill. B csíkok vannak benne.
