Mitsubishi WS55807 Converge prob.

Hello, I have a convergence prob. I will work great for about the first couple of minutes when I turn it on then pop out. I have a service manual but still don't know where to find the converge chips to check the soder or pins. Could you show me where to look or explain where or what to look for. Thanks Nate

The red color stops working. If I tap the convergance board it sometimes pops back in.


If ws55807 it is not bad connections on the middle board where the two STK-392-570 convergence chips are.

I have seen this over 100 times in these sets. What happens is the pins break loose inside the chips----I have had ones where I unsoldered the pins and some just fall out--only the solder trying to hold them in.

The good news is Total parts cost for the repair on EBAY (I use a seller there) will be about 15 for the two chips and should be under 30 total for everything needed.

I also have start to finish step, by step instructions for this repair in this model---tell you everything you will need and the best way to do it.

I will attach a photo of a typical convergence IC---yours are up front on the middle board facing the front of the set.

If this information told you something you did not know, rate this solution as very helpful as I do this here for free.

The red and blue colors are way off i tried to converge adjust the colors no results


Ur tv have convergence problems,it dead.Any colors misaligns,3D pics,shadows pics.The tv convergence board must have it the 2 STK convergence ICS and some or all it resistors are dead,must be change to solved convergence problems.The shop will cost U $300-$350 for parts and labors.

Unable to converge vertical blue gun


The convergence IC's probably need to be replaced. Unless you are savvy with electronics, I would not attempt to fix it. Call a professional. I would estimate a repair cost of aprox. 280.00 to 350.00.
Hope this helps,

Concaved distorted picture in 1080 Mitsubishi 65" TV.


This is a convergence rpoblem that is either bad connections on the pins of the convergence ICs or defective ICs. If you can solder and are comfortable working inside TVs where there are potentially dangerous high voltages, let me know and I'll provide additional details and instructions for fixing this yourself.

Auto Converge


If the message "sensor is unresponsive" crops up then the problem is definitely electronic and lies somewhere in a loop that starts near the tube base, goes to the main board and back to the tube base. However, you can try to do a manual converge by adjusting the ring permanent magnets on the neck of the tube (right behind the scanning coils) while something is being displayed. Normally these magnets are secured with a clear glue to minimize drift. Use a heat gun to soften the glue and then turn the ring magnets around until you are happy with the picture. As you know, this part of the TV has some pretty dangerous high voltages so try to keep your left hand in your back pocket while doing these adjustments with your right. Good luck.

I had this problem and corrected it by resoldering all 36 pins of the 2 convergence IC's. Biggest problem was getting the circuit board out far enough to prop it up and get underneath and get at the solder connections, required unplugging a few cables, 3 screws holding it in. Works great now, I used to fix it by taking the back off and banging on the Heat Sinks which house the IC's, I could tell then that it reacted like cold solder joints. I decided after a field service guy charged us 95.00 for a service call and quoted 650.00 for a repair. Hope this helps someone.

Three colours don't converge


Sounds like your convergence power supply board is bad if it is a ctc or ptk 195 chassis. Located above the main board on the left and dynamic convergence board on right. Has two plugs and held down with quarter inch screws. Most problems on the board is the IC on the metal heat sink which is stk 730-010. whatever you can see the part number on it. Unsolder with solder wick and solder in new. If this doesn't fix a new complete board will do.
