Mitsu Proj TV WS-65711 needs Converg IC chip. Part Co$t + labor?

Let me know if I can be of further assistance.

i believe i staed ina similiar case that you seem to be having a over heating of the circuit chips on the mother board. are the cooling fans in the set running.

Go by number on your ICs If they are STK392-570 then use STK392-570 only! Call Mats for parts 10.95 each 1-800-628-1118 They are Big Black ICs mounted on Big Aluimmim heat sink will have STK on them!

2,2 is short protection.

98% chance the fuse or fuses (there are two 5 amp pico fuses) that protect the convergence circuit are blown. If you find F9AO4 OR F9AO5 on that board check them--if either is open the STK-393-110 DID IT.

Fairly short life for this chip if it was installed correctly and had heat sink compound applied to it--once in a while you get a bad one.

I have had my WS-65511 fail like this, first at 4 years, second 2 weeks later, then 3rd time yesterday (4/14/2009). In past, the tech replaced a thermal sensor p/n 299P313010A (but Mitsubishi says that part is not for WS-65511 and that it does not have a thermal sensor - go figure). It is a white rectangle with about 30 pins in 2 rows and is soldered onto a board in the TV. List price is about $25.

This issue is almost always caused by a faulty Convergence IC inside your TV. These chips heat up and can become damaged over time. The most common cause I have seen for the picture distortion is the heat of the Convergence IC weakening the solder connection to the TV circuit board. If you look on various messages board you will see people rigging wooden dowels and other items to apply pressure to the chips in order to correct their picture issue. This works because when the solder joint is weakened the chip becomes loose and vibrations or pressure will cause it to work or not work correctly. Aside from all that information the correct fix is to have the IC chips replaces on your TV.

The solutions for this issue are as follows:

1. located a tv repair shop that will replace the parts for you. I had the same issue with my 65" Tv and the quote was $350 for the labor and parts.


2. You can ordered the IC replacements yourself online by going to google and looking up a reseller of the STK392-110 Convergence IC that is inside your model TV. You will need 2 of them and they cost around $6 each. If you have the soldering skills to remove the old chips and install the new ones this is by far the most cost effective route. It is a fairly simple process and guides can be found online.

I also have the blinking green light problem with my WS-65513 Mitsubishi TV. I would appreciate any information you could send to help fix this problem. Thank you, Keith. elitemachine @netnitco.net

Don't feel bad about Mits. All the projection companies and all the new TVs have markedly poorer reliability than the good old CRT types. You should see all the class action lawsuits against even some of the best companies!

The power supply section is not working.
Common possibilities are:
- Convergences amps have failed overloading the supply
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.

In short, you need a experianced tech to troubleshoot this.
