Recently my plasma quit working. The Vizio logo still lights and LEDs on the Logic board light up when you power on the TV. Also, I can hear a relay on the Sanken pkg 1 board click when it powers on. I thought I could fix it myself, however without a schematic this is proving a challenge. After reading some posts on this forum and others, I was able to do some basic troubleshooting with my DMM. I think I can eliminate the Y-sus and Z-sus boards as my problem. According to a label above one of the power supply boards I should see 195v on the Vs leads. I get less than 1v. Same thing from the Va lead, it should be 65v. At this point I am confident that one of the three power supply boards is bad. If anyone has a suggestion how I can determine which of the 3 Sanken boards is the culprit I would greatly appreciate the input.
Thanks,
