Re: LG 42PC3D - Flashing picture, sound works

Thank you! Sorry for not catching that on my own. I appreciate it!

Re: LG 42PC3D - Flashing picture, sound works

Thank you both! What's the part number for the ysus IPM?

Re: LG 42PC3D - Flashing picture, sound works



Lol! I'll double check the voltages! Thanks for the heads up! Looks like it's going nuclear soon!

I'll check the voltage on the caps. Hopefully I don't botch that too!

I appreciate the feedback. Is the clicking IPM on the ysus a problem or is it just a function of the Zsus failure and will most likely go away if/when the zsus IPM is replaced?

Lastly, do you happen to have a part number for the zsus IPM?

Thank you again!!...

First off - I'm not a pro at all, but I know how to use a multimeter and have basic electronic knowledge.

All fuses on Zsus and Ysus test fine. IPM on Ysus is not shorted anywhere (except the grounds, obviously). Va and Vs both show voltages that are roughly double the label on the panel.

The TV flickers 2-3 times/second. You can "see" what's on the screen but the colors are significantly off. With every flicker, you can hear a "click" from the area of the IPM on the Ysus board (i.e. about 2-3 per second).

Any idea where to start?...

Hi all! I ended up here looking for help (or at least confirmation I did my research correctly) on the issue I'm having. I have a LG 42PC3D. I believe the ysus board is bad.
