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.
