Question about Mitsubishi WS-55809 55" Rear Projection Television

Mitsubishi WS-55809 2-2 code

I have a mitsubishi WS-55809 with a 2-2 code. I think the IC's may need replaced but I have to check to see if the fuses are blown first. Do you have a schematic or any additional information that would be helpful in troubleshooting this problem?

thanks,

STeve

    I pulled the board and the fuses both checked bad. Can you verify the the convergence IC's are labeled IC3E01 and IC8A50?



    thanks for your help!

Look on the center board where the ics are and check F9A04 and F9A05 pico fuses, if they are blown you will need to replace those two 5 Amp picos and the convergence Ics

    the convergence Ics are IC801 and IC802 they are stk392-570

    check the wire clips to see if they are all secure and hooked properly, as a 12 code means no error detected.

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.

I just replaced the 2 ic chips (stk392-570) and the 2 pico fuses at f9a04 and f9a05 that were blown. The tv powed up for about 10 seconds then turned off again. Now i'm getting the same 3 second power...


You have bias resistors close to the IC's, I would guess you have a few that have changed in value and therefore have destroyed the IC's again. Now you must start over again. The resistors will be very low Resistance and tolerance and they must check exact.

22 is short protect usually its the convergence Ics in that model that can short out. check fuses F9A04 and F9A05 if they are open its most likely the convergence ICs that need repslacing. If you need further assistance, please reply to this same post.
