If F9A04 and F9A05 are open the convergence ICs will need to be replaced as well as the two pico fuses. You will need two STK392-570 Convergence ICs and two 5 amp pico fuses. You ca get the replacement parts at the following link with free installation instructions. heres thelink.

Over 95% of the time a 2 - 2 blink code on that model is a convergence output problem. You need to replace both of the convergence output IC's and perhaps the pico fuses feeding them voltage. The pico fuses are F9A04 and F9A05. They are on the same board with the convergence outputs.

SOURCE: Mitsubishi ws-65809 powers on for 2 seconds.

2,2 error code is short protection---98% of the time it means one of the two soldered in pico fuses this set uses is blown----there are several---but your problem means if it is ws-65809 one of the two stk-392-570 convergence chips has failed.

I will attach a photo---they are on the middle circuit board and the two to the right are for convergence--both are green and 5 amp--with the set unplugged check both of them like any fuse--no reading means bad.

If you find this--I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS SET--SHOPS WILL GET 300 or more but you if you can do it yourself buy everything you need for under 40 dollars--I can tell you the best place to get the chips, fuses, etc.

If you want the instructions let me know and I will post them here for you---they are based on my own actual experience doing this repair in this kind of set hundreds of times.

If this information helped you rate this solution as I do this here for free.

Here is a photo of what the two chips look like--The one in the picture says 392-560 but yours uses two that look just like it--STK-392-570.

Try to unplug set and try it again as if the set was unplugged and then the self check done it will be 1,2 which means NO ERROR detected.

Let me know also what the set does?
