Sziasztok!
A címben említett tv áram alá helyezés után bekapcsoló gombra reagál, relé a tápon kapcsol, majd el kezd szépen "lassan pulzálni" (villogni) pirosan a led, de itt meg is ragad, nem megy tovább! Táppanelen minden táp megvan és a mainboardon is. Ami fura, hogy a MICOM a mianboard tápokat bekapcsolja (POWER_ON/OFF2_1, POWER_ON/OFF2_2), viszont nem kapcsolja be az LVDS tápot és a háttérvilágítást sem és a SOC_RESET magas.
Kifogytam az ötletekből, valakinek esetleg valami ötlete, tapasztalata?

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.
Üdv!
Ebben tudna Valaki segíteni?
.....vagy qka??
Kösz
