I have a Mitsubishi ws-55711 I push the power

2,2 is the error code for short protection.


The most common reason for this is one of the 2 pico fuses that protect the convergence circuit is blown. Changing the fuses will not help! They are green in color and soldered into the middle circuit board and are F9a04 and F9a05----look like resistors but are 5 amp fuses.

99% chance if one or both are blown---you have to have someone change the STK-393-110 convergence IC that this set uses----the IC can be purchased on Ebay for under 14 dollars and the same seller sells the pico fuses 5 @ 2.95.

The best thing to do here if you or someone you know is able is to unplug the set and look for the fuses---middle board towards the back---there are 5 of them and the two closest to the back of the row are for the convergence IC----If someone checks them (like testing any other fuse) you will know--if either or both is blown--the convergence IC got them.

I have start to finish, step by step instructions and photos of the fuses etc----If you or someone you know can solder and is handy--you may be able to do the repair yourself.

If not, shops usually charge 300-400 for this kind of repair in this set.

LET ME KNOW IF YOU NEED ANY ADVICE or help.
