Mitsubshi WS-65909Error code 2-2. i would like to know how to fix
The fuses are not the only problem--if 2,2 error code 95% of the time the Convergence IC that the WS-65909 uses is bad. It is a STK-393-110----fuses are on the same board and near the middle towards the back---they are green in color and look like resistors--if you have this model the location numbers marked on top of the board will be F9A04 and F9A05----both are 5 amp fuses (this will also be marked on the board) they are 2 of about 5 fuses and are towards the rear of the row of pico fuses.
If you check the fuses (just like any other fuse) and either is open--You need to remove the center board and replace the STK chip and the fuses-----not everyone can do this repair themselves--
I have had so many people ask me about this problem that I have composed step by step start to finish instructions for this repair--If you have some skill at soldering and think you can remove the board safely let me know and I will post the instructions here for you to read.
Other than the fuses there are about 12 light blue resistors in front of them that need to be checked--if any are discolored they need to be replaced also--they are all low value resistors--3.9 ohms--they will check like a fuse--no reading and or discolored and you need to replace them.
Considering the parts cost is usually under 20 dollars--I can also tell you the best place to buy the chip--you can if you can do the repair save a lot of money--most shops get 300-400 for this type of repair.
If you find the fuse or fuses bad---do not bypass or replace them--the only thing that gets them is the convergence chip.
If you have any questions or need advice let me know--I am here to help people.
