Question about LG 42LG50 42 in. LCD HDTV
My LG 42" HDTV (Model L2LC55-ZA.AECYLJ) has suddenly stopped working. I have power going into the unit but the red standby led is not lit. Any Ideas please? Could it be the internal power supply unit?
If you do not get any light on the front panel, it means the 5vdc standby power supply is not working or failed main logic board, you will have to do the power supply inspection first.
