Vizio VP422HDTV10A picture problems

[fixitelectronix]

I have a Vizio i just ordered a new "X" board for(atleast thats what its being called) I assumed it would be the "Z" board but its not. Anyways, I was able to get the tv to power up and display a picture. Now the picture is showing a lava lamp effect which points to the "X" board again. The 2 Ribbon cables going to the "X" board are sparking on the frame. When i adjust the voltages on the X and Y board, picture improves but doesn't fix the bad color. Main voltage on the Y board was 180-186. If i lower the voltage to 120, it fixes the lava effect after a few moments. I've checked the service manual with no help. Thinking it might still be the X board. But looking to see if anyone else has had this tv with the same problem. THANKS!!!

Can you show us a picture of the fault?

I apologize for the late response. I work 50 hours a week or more during the holidays. The first picture is before I turn down the voltage on the y sustain board. The second picture shows how it clears up but even if something is on the screen, I still have color distortion.

That could be an X- or Y-main fault. To locate the exact fault the voltages on the various boards need to be tested; please post a picture of the X- and Y-main boards (right and left hand boards, looking from rear of set)
