SOURCE: error code 22 on a Mitsubishi WS-55907 55'' HDTV

your set is the V17 series so a code 22 means short protect. Which means the TV has a short circuit condition and is shutting down to prevent further damage. You can get a manual for the V17 sereis at the following link for 15.99 and they will provide free unlimited support to help you with the diagnosis and locating parts. Your set is coverd in the V17 sereis service manual under the mitsubishi section. Here is the link in case youd like the service manual and free support.

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: Mitsubishi WS-65857 has a trouble code 22 which I

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.

I have a projection television ws 55809 it turn off everytime i try to turn it on i did the test an 22 was the code what is it and how do i fix it

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)
