Reverts to st/by at sw on with 2 or 5 flashes from LED5 flashes indicates an AKB error (Grey Scale Correction). This is normally due to LOP shut down & there is no EHT or sec line volts. Normally due to faulty R618 (270K ohm). This res is in the current sensing cct & could therefore potentially give you an over-current error (2 flashes).

Assistência TécnicaAs dicas apresentadas destinam-se a técnicos de eletrónica, a tentativa de reparação ou assistência sem ter conhecimentos de eletricidade e eletrónica, podem provocar danos mais graves aos equipamentos e, devido a tensões muito elevadas em alguns circuitos, graves danos fisicos que podem constituir um risco em determinadas reparações.

Não arrisque reparar equipamentos com tensões elevadas se não tiver conhecimentos técnicos para o fazer em segurança.
