Odd. You have good Vs, Va but no outputs from either board. Is control board LED blinking?

i only get good Vs/va when I disconnect CN 5000 from the Y-main...when I connect CN 5000 I get multiple clicks from the relay, humming sound to the x-main, and no Vs/Va from PSU

One thing to check is if you get good voltages with X-main unplugged from Y-main.

what I don't understand is the initial problem with the set was spackling on the screen..I removed the Y-main to check for shorts and found none.when I re installed it, thats when I started getting the problem with the multiple clicking from the relay. So if the LED on the control board is blinking, does that mean the control board is fine?
Blinking light indicates control board is running.
When you removed the Y-main it's possible you damaged it from ESD...

You can adjust Yrr/Yfr on this set to eliminate that later. I have done it before on the PS42B450. (Same TV, different main board & badge on front.)

Okay...thank you for all your help, I'll order a new or used/tested Y-main from ebay unless you recommend somewhere else?? I'll get back to you with my progress
