Correct, convergence output chips are getting heated and causing problem. Replace them to solve tv issue.
Also check dry solder connection nearby these chips, resoldering these solder connections will cure dry solder joints problem as well.

Turns off as soon as I turn it on. ws - 65819


I had the same problem. The repairman said the Convergence ICs were bad, located on the big aluminum heat sinks on the center board in the TV. He replaces both, and a couple of fuses (that look like resistors).

The tv worked fine for a couple of days then did exactly the same thing. They are coming back out to fix it next week. If there is anything different, I'll post an update.

Mitsubishi WS-65807 blinks '22'


Jim,
yes the convergence Ics are what cause the two picos to be open they are both 5 amp picos. You can get the picos, the convergence ICs and the factory service manual for your model at the following link.your model is known as the V17 chassis for service manuals and you should require two STK392-570 Convergence ICs. Heres the link they provide free instalation instructions.

I replaced the pico fuses and the convergence IC's. fuses poped right away code 22 . Further inspection of the board showed the coolant had leaked out of the center projector and fried the board. Not willing to pay $300. Passed it on to someone else

You have bad convergence Ics they are mitsubishi part # 267P150010 Generic part is STK 392-570 and they are at locations Ic8c01 and Ic8co2 on the deflection board. If you can solder you can take these out replace them and fix your problem for about 100 dollars. Best of luck
