LG 50PC1DR doesn't power up. Just clicks.

Re: LG 50PC1DR doesn't power up. Just clicks.

Rechecked several times this morning. Vs is showing average voltages in the mid 50's. However sometimes it will only register maybe 38 but my multimeter's display seems to have a slow refresh rate so maybe it's just not up to voltage yet?

I've literally got about 2.5 seconds in between clicks and it does not vary at all, very consistent amount of time between clicks.

Again, this was with everything hooked up except the harness going into the top of the Z SUS board. My digital camera is able to make videos, or I could take more photos if that would help.

Thanks again!

OK, right now it sounds like your power supply is bad. It also seems like there is a Va short elsewhere, so you may be looking at replacing/repairing the Z-sustain too.

A common fault on these is the 68n capacitor, blue, on the primary side. However, I'm not certain it can cause your fault.

Thanks Tom. When you say 68n capacitor, were you referring to the ones I've circled in this picture on the Z SUS board?

I've pulled and inspected all of the boards in the TV except the logic board and everything, at least visually, looks flawless. Of course it can't be something simple

It's on the power supply, a blue box approx 1cmx2cm marked PILKOR 68n I believe, may be different.

Alright I have replaced the y sus, the top and bottom y buffers and the power board and I still have the same issue. TV clicks and will not start, I would like to know what voltages should the pins be reading for p 805. I am wondering if the power board I have recently acquired is bad.
