Question about Mitsubishi WS-55809 55" Rear Projection Television

Where to buy F9A04 and F9A05 fuses (Mitsubishi)

I have a Mitsubishi rear projection tv. Through forums like this, I've figured out I need the F9A04 & --05 fuses. I get the 2-2 diagnostic flash and have proved it out with a simple continuity test. My only problem is finding a place that sells those fuses. If anyone knows of a store in the Worcester/Boston area of Massachusetts, I'd really appreciate it.

Those are called "pico fuses" and marked value is on the board, probably 5 amp. You will want to replace the STK IC's mounted to the large heat sink also. Any TV repair shop should be able to help or supply the parts you need (policy permitting).

How do i test fuses on a circuit board?


F9A04 and F9A05 are the two picos to test. They are both 5amp pico fuses they will appear lime green and look like resistors without color bands. They are located on the same board as the convergence Ics. Just test them for continuity with a ohms meter.
