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: My mitsubishi ws-55809 will not turn on

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

Two blink code on this set means Usually one of the two pico fuses that protect the STK-393-110 CONVERGENCE IC is blown--the fuses will need to be tested and the chip and them replaced--


If you have enough skill I have step by step start to finish instructions for this repair in this set---set detects one of the voltages to the Chip is not there and shuts down instantly. I have photos of the chip, fuses and protect resistors this set uses also.


If you want the instructions for free give me a email and I will send them to you for free--if you are able to do this repair yourself you will save a lot of money--you can buy the chip on Ebay for about 14 dollars plus shipping and the same seller sells the pico fuses..............


If you want to attempt this give me a vote here--If you are not able to do it yourself I have suggestions for you about getting the set fixed--I have done hundreds of these sets!

Just reply to this post here.

Let me know what you want to do, I am here to help people
