defect tv led Orion

Recommended Posts

Am primit un tv Orion T 22 D/PIF/LED.

Problema e ca nu are imagine. La pornire ecranul devine un "altfel" de negru, se vede ca are backlight. Canalele se pot schimba, sonor are.

Care poate sa fie problema?

Este primul meu tv cu led. Ce sa masor si unde? Merge de la 12V. Dand jos spatele se vad ledurile luminand.

Pe firele rosii si marcate cu rosu trebuie sa ai 5 sau 12v functie de ecran. Este alimentarea lui. Daca tensiunea exista reparatia este mai complicata pentru un incepator.

Firele rosii sunt puse in paralel. Mai este o placa electronica lipita de ecran. Si de acolo poate fi problema. Este insa ceva mai complicat de reparat daca nu ai mana formata si sculele necesare.
