Download the service manual to your Mitsubishi TV from here. It will have details about all error codes.
What you have is short protection--it means one of two pico fuses on the middle board is bad and it and the two STK-392-570 chips it uses for convergence are going to have to be replaced and the set adjusted with the Mitsubishi remote.
This can be a do it yourself repair for some people with basic skills and parts cost from a site I know will be under 30 dollars.
In addition I have my own start to finish, step by step instructions for this which are available if you provide a email address.
They tell you everything you will need and precisely how to do the repair. Once you have and read them you can decide if you can do the repair or not--shops usually get over 200 dollars parts and labor for this repair.
I attach a photo of the fuses (on middle board) and what the chips look like (also on middle board at the front)
like this but will have the 570 number on them.
thank it works
my tv is fix thanks so much

Hi, after lookin in the service manual I have a question. I tested th see if the fuses were shorted, however... I'm not completely sure how these fuses work, since most fuses are shorted to begin with... Are they resistive type fuses of some type? Just looking for insight. Thanks
SOURCE: WS-65809 ERROR CODE 22
look on the center circuit board and you will see two green Pico fuses they look like resistors but they dont have any bands on them . They will have F9A04 and F9A05 on the board next to them. Check with a ohms meter if those fuses are open you will ned new convergence ICs. Thats the first thing to check are those two pico fuses when you get a 22 error on your model.
SOURCE: I just replaced the 2 ic chips (stk392-570) and
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.

hi..
The problem is the Convergence circuit and the reason it does not power
up is that one or two of the 5a pico fuses have opened when the
Convergence IC failed. It is either going to be a pair of STK392-570's
or a single IC STK393-110. That is as long as this set is a Mitsubishi
made in the last 7 to 9 years.
I would estimate the cost to repair 280.00 plus service call fee if any, plus tax on parts.
Let the Tech check it out. If if it cost less than 400.00 to repair, it may well be worth taking the chance.
thank u

To the other expert he has the codes and quite a bit more, if he has trouble with his remote maybe you can help with that.
