Question about Mitsubishi VS-5043 50" Rear Projection Television

1 Answer

Blown fuses I have found fuses F9A04/F9A05 blown. Once I replace it I'm worried that I can't find was caused them to blow. I have found some posts that say it's the convergence output board. Can you help.

I just replaced the 2 ic chips (stk392-570) and the 2 pico fuses at f9a04 and f9a05 that were blown. The tv powed up for about 10 seconds then turned off again. Now i'm getting the same 3 second power...

You have bias resistors close to the IC's, I would guess you have a few that have changed in value and therefore have destroyed the IC's again. Now you must start over again. The resistors will be very low Resistance and tolerance and they must check exact.

Won't power up.

Check the center board for two green 5amp Pico fuses F9A04 and F9A05 if those two picos are blow, replace both STK392-570 convergence ICs on that same board and the set will be repaired. Fuse F9A05 will read open in circuit but F9a04 wont so its best to lift one side of those two pico fuses out of circuit to check them. (* % of the time a 22 code in that chassis its the ICs having shorted and it will blow those two picos. You can get replacement parts at the following link.
