Re: LG Plasma 50PC1R-ZH

So.. I've been quite busy lately but now I'll have a go on the TV again.

I heard that the Y-SUS boards are prone to failure. I am thinking of replacing it since I'm not very good with the multimeter.

If the Y-sus is defect, would disconnecting it result in the TV starting up? Because I've tried to disconnect it but I get the same problem, the famous clicking noise and then back to standby.

Thanks in advance!

What am I looking for, where can I find it and how do I measure it? ...

Hello everyone!

I bought a broken LG Plasma few weeks back thinking I could fix it. I have repaired computer LCD's before that had bad caps and from the sympoms of this TV it sounded just like that would be the case. But no..

When I try to power the TV on the red standby led on the front of the tv starts blinking in white and I can hear a relay clicking. It only clicks once and then it powers off again. It will not start up, dosnt matter how many times I try.

I could not see any bad caps during my visual inspection of the PSU so I bought a new one and...
