there are fuses on each driver (6 in all) under the heatsinks usually.. make sure these are good. there are also 2 5amp fuses on the g board that supply power to the chips + and - 24volts.. check both of these.. i've seen some check good in circuit and still are bad, check voltage to see for sure. In a rare case, i knocked off a small surface mount resistor when unsoldering the chip, and then the convergence was muted.. make sure no small surface mount parts were moved on the bottom of the board when you soldered. good luck, let me know wif you need futher assistance.

I am told I might have a fuse out on this tv. Anyone know where I can find the fuses?

Very rarely is there any fuses that open up on TV's. There are usually fusible resistors or fusible links that don't look like fuses at all open up. Mind you more than not a fuse or link will open because of an underlying issue with the TV. I suggest you have a technician look at the TV for you.

Mitsubishi WS-65857 has a trouble code 22 which I think is short protect. Would anyone know the cause of this problem.

2, then 2 blinks is short protection.

Usually this means in this set one of the two pico fuses that protect the convergence circuit is blown.

This model uses two of the STK-392-570 CONVERGENCE IC'S.

What you need to do first if you are able is remove the back cover and locate the fuses---I can tell you where they are on the board. Check both of them just like you would check any fuse. If either or both are blown----you have found your problem. The set will detect if either or both are bad that no voltage is reaching the Convergence circuit and it will shut off.

I can tell you the least expensive place to get the parts and I have step by step start to finish instructions for this repair if you are handy and know how to solder etc.

Considering the total parts cost would be under 25 dollars--if you can do this repair you can save a lot of money--most shops get 300-400 for this kind of repair----I know as I have done hundreds of these repairs----did a Mitsubishi a few days ago with the same two chips bad---about one hour for me in the customer's home.

I have photos of the fuses and location also--if you decide you want the instructions and photos we will find a way to get them to you. I am not permitted to give MY email address here--if you know what I mean.

If you have ANY QUESTIONS OR WANT the instructions etc---let me know--I am here to help and I do know a lot about this type of set.

First thing is for you to find out if either of the fuses is gone----if they are----you MUST change both chips and or fuses etc.

Hey anyone, I need help... I have a Mitsubishi ws-65807. It was manufactured october 2000. I lost the sound about a year ago...just started cutting in and out then finally went out altogether. Not a...

You had a convergence circuit failure. When it failed you had a fuse for the -26v line open and probly the +26v fuse open. The convergence circuit in this set is on the powersupply board and is real tricky to to take out because of hidden screws on the heat sink that also hold the board in place. I would call a Mitsubishi Service facility to repair it. It will need either a pair of SKT 392-570's or a SKT393-100 and two 5A Pico fuses. As far as the sound going
out, it could be a bad Audio output Ic, it happens to be on the same board as the Convergence circuit. What bothers me is that
some of these models have had a leaking issue of cooling fluide from the crts. On Some models they had mounted a tray under the crts, other models they did'nt. Right where the Audio output and the Convergence circuits are is a prime place for this fluide to leak. You can varify this by taking the speaker geill off the front, remove the screws holding the front wood cover and right on the center board near the front of the board you would see clear liquid dropplets and or corrosion of parts due the liquid that had leaked. You really don't want to know how much it would cost to replace the crts and the Power/Convergence boards if they are available. We are talking replacement of TV if that is the case. I hope I did'nt scar you, but it is a possibility. Let me know what you find.
Hope this helps,

Where to buy F9A04 and F9A05 fuses (Mitsubishi)

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).

The model number helps but the chassis number is very important.
