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 32LV3400 TV nem indul
Sziasztok! Egy LG 32LV3400 LED TV nem indul. Egyedül a 3,5V van meg. Az előlapi LED kékes-lilásan világít (s nem kék, se nem piros, ill. mindkettő). Az alaplapra megérkezik az "ON" a kezelőegységről, de utána már semmi. Sem a 12V "ON" , sem a 24v "on" nem megy a tápra. Tudna valaki segíteni? (szerintem alaplapi gondja van) Köszönettel: Attila
LG 32LE5500 ledes lcd tévénél nincs háttér világítás.
Sziasztok! Segítségeteket kérném, mert nevezett készülék javításánál elakadtam. Bekapcsolható és rendben működne, ha lenne hátér világítás. DE nincs! Ledsorok teszterrel ellenőrizve jónak tűnnek. Nem bontottam le, de az összes "csoport" egyforma jellemzőket mutat áramfelvétel terén. Viszont egy furcsaság feltűnt a táp/driver mérésekor. A panelon, adott kijelzőhöz 99V szerepel. Ez nálam 89V. Ez a driver tápfeszültsége. Nem tudom a megadott érték lenne-e tényleg a helyes, mert akkor akár ez is okozhatja a hibát. Talán volt már valakinek dolga ilyen készülékkel és emlékszik... Köszönettel: Kiss Zoltán
