Parts for $80 to 90?!?!? HOGGWASH!! It's $21 at mcmelectronics.com for an orignial Sanyo. For a WS-65711 it is indeed a STK393-110 and you only need one of them. I've heard that this usually the culprit when there are convergence problems. The pico fuses can go, but that's pretty rare. If you can solder and feel comfortable inside your TV, then this can be done at home so you'll even save on the labor. I suggest buying the part yourself and asking them to install it.

There is either a pair of STK392-570's, or
a STK393-110. Probly also 1 or 2 pico fuses for the +/- 26v line in the power supply.
Parts aprox 80.00 to 90.00
Labor 150.00 to 180.00
Plus service call fee if any.
So figure it up from there. Labor cost does vary from location to location. I do feel confident that capasitors are not causing this problem in the way you explained the symptoms.
Hope this helps,

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!

Mitsu WS-55859---turned off & only powers up for 2 secs


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.

My Mitsu WS-65511 will not power on. When power is pressed on tv or on remove solid green light comes on for a moment as if television is going to come on and then it just shuts back off. I have tried...


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.

Mitsubishi 1080 hd ws-65809 wont power up


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.

TV Shuts off by iself!


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.
