Re: LG 42LC2D Power Supply Issue

I disconnected all the connections from the power supply board. Oddly enough, the only voltage present when AC power is supplied is the 5 V. There are no other voltages present.

That I didn't as yet try. But I can do that.

Re: LG 42LC2D Power Supply Issue

Sorry about that. Same P/S, but for a LG 42LB1DRA.

No 5 V with AC power. But, when first applying AC power, there is 5 V on P201 but for just a split second. Nothing afterwards.

Thanks....

Re: LG 42LC2D Power Supply Issue

Hi all,

I had a similar issue. A number of the p/s caps were "pregnant." I replaced them with higher voltage values, and the TV has worked fine for years. But, it started acting up again. A couple of clicks after power up, and then nothing. None of the caps look bad.

Now, I do not have the STBY 5 volts present. There was mention of the AC optocoupler issue and the (lack) of 5 volts. I cannot find that issue mentioned anywhere else. Nor can I find a schematic for the p/s.

Could someone enlighten me...
