I have a Mitsubishi WS-65807 65" rear projection TV that just decided not to power up anymore. When you turn the power on, the led lights and then the set turns itself off.
I researched the problem and fout out how to 'read' the error, and it's blinking a '22'.
I pulled the center board and checked pico fuses F9A04 and F9A05 and they appear to be blown. I plan to replace both of those, and I suppose I should replace the STK392-570 convergence ICs too?
Any help would be appreciated!
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

I also have code 2-2 with power on it turns off in 1-2 sec. no picture. I haven't found the ic chips yet but I did find the pico fuses. I'm going to test the fuses, but everything I've been reading says to replace the ic chips and any open fuses.
Hope we can get a sure answer. A lot of forum topics just end with no result :(
