Technika 32L-244 LED TV, háttér nem világít! Samsung kijelzővel szerelt, SSL320_OD3A a led meghajtóval,Megoldva!
Sziasztok!
Tegnap hozták azzal a hibával hogy nincs kép rajta, de a hang van. Kipróbáltam a készüléket a hiba az hogy nincs háttér világítás, de megvilágítva van rajta kép. Ma szétszedve a kijelzőt 15 Led-et cserélni kellet , de bekapcsolás után csak felvillantak a ledek, és megint 5-öt cserélni kellett. Ezután kipróbálva megint csak felvillantak a ledek, és megint zárlatba ment több led. Most csak a háttér van bekötve, a kijelző nincs is rákötve, többször is így szoktam kipróbálni a a led hátteret, de most csak a 4db megmaradt gyári led maradt meg. A táp és a main feszek rendben vannak, de a led meghajtón nincs meg a kimenő fesz, aminek a száma: SSL320_OD3A,  A kijelző ami benne van: SAMSUNG LTA320AP33, a led csíkok: SVS 320 AA6 , a 7LED-esből 2db a 6LED-esből 1db van. Most led szalagot kellene hozzá szereznem, vagy a meghajtó panel lenne rossz, mert ez benne van a háttérnél, de ezt átmérve nem találtam benne rossz alkatrész, vagy valamelyik ic lehet rossz? Ebbe milyen ledet kellene rakni? Válaszokat előre is köszönöm!
Samsung TV GU55AU7179uxzg Does not Switch on suddenly
Hello everyone,

i am new to the forum and i would like to save a TV from the dumpster. I figured out that IC207 is broken on the mainboard of this TV. Does anyone have a schematic for these kind of TVs or even have the same and knows what IC this is? I presume it is a voltage regulator. The TV is totally fine but does not turn on any more. The power supply is perfectly fine. I desoldered this IC as it was getting very hot and was the only issue i found.

Thank you!!!

Tisztelt Kollégák! Az a probléma a fent nevezett tv-vel, hogy hang van, viszont kép egyátalán nincs. Ha a G2-t megemelem, látszik nagyon halványan a kép, és a visszafutási csíkok. Találkozott már valaki ennél a ipusnál ilyen hibával? Köszönettel: Dóra Tamás
