Good morning group: As recommended by Jeff Dougherty Tips came from Tech Repair CD 1. Unplugged yokes one at a time. Nothing changed. Tip said Green yoke. 2. Check C524 out of circuit. Checked good. 3. Checked R860, R857 and R858. All good As recommended by Robert from H&H Electronics Change STK392-110. No change. After closer examination of the circuit board, the one on the left when looking in the back. The one with the convergence IC?s, dual tuner and a ton of SM IC?s. The only numbers I could find that might be the board number is TNPH0370. Anyway something has been spilled onto the board. It was all gummed up in-between the SM IC pins. Tried cleaning it with board wash. Did not help. Looks like board replacement time. I called Try-State Module and they are not set-up to work on them yet. Did say they would be in about month. Might keep that in mind. Called Panasonic about the board and they put it in research. Haven?t hear back from them. Know it has to be expensive. Ernie from Valley TV was trying to download the manual from Panasonic website. Must not have had any luck. I guess I am on hold till I get the schematic or a new board.
