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 28mt49vf és 28LB490u maint vennék, vagy eladó
sziasztok

LG 28LB490U
EAX65588502

Ebbe a 2 TV-be vennék működő maint.
Az első nem indul standby-ból. Ha a flash-t újraírom 1x elindul, de miután kikapcsolom többet nem indul.
A második villámos..

Vagy eladó a 2 TV kompletten táv és tápegység nélkül.
LCD OK, .

LG32LB561B TV Kikapcsolás után,(pár óra elteltével,bekapcsolás után)újra kell programozni. A nyelvet és a csatornákat elfelejti
Kedves kollégák.
Ennek a készüléknek az SPI Flash IC-jét újraformáztam és programoztam,majd (mivel nem javult a helyzet) egy másikra kicseréltem és azt is újra írtam.
A készülék még sem javult meg. Esetleg a NAND Flas IC-t kellene kicserélni,vagy programozni. Kinek mi a tapasztalata erről a hibáról. Nem is beszélve arról,hogy egy másik régebbi LCD LG TV az meg a csatornákat bekeresi,de nem menti el. Úgy,hogy most ilyen gagyi hibákkal találkoztam.
üdv.
