Sziasztok!
A LG 42LF5610 TV-be visszaforrasztva a koax csatlakozót nem érzékeli hogy antennát csatlakoztattam hozzá (Telekom DVB-C). A TDJH-G301D típusú tuner megkapja 3,3V-ot. A soros (valószínűleg) kondenzátorhoz szakadásmérővel szakadást nem mértem a panelon.
Valaki tudna benne segíteni, előre is köszönöm.

LG 55LM6200 Screen goes dark after a few minutes, suspect protection mode is engaged-- no sign of thermal issue. On power board there is a LED, blinks amber in 4 blink cycles. Measured voltages ok, both backlight strips appear to be good. I have the SM, there is no reference to this power board LED, beyond the fact that it is there. Does anyone know what the blink codes are for these LG power boards? Thanks!
Sziasztok.
A fent említett tv került hozzám javításra.Bekapcsoláskor jó a kép és kb10 perc után becsíkozódik meg kockás lesz a
kép.Mintha szűrés probléma lenne de a táp kondik cserélve lettek.Kontakt hibát nem vettem észre,néha már a bekapcsoláskor is jelentkezik a hiba.Készítettem pár képet a hibáról.Valakinek valami ötlete?
üdv Attila
