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

Hello, I purchased and installed one


You will need a original remote to make the changes to the multipoint and single crosshatches. Do a google search for remote controls to find the Philips remote.

hi
your convergence circuit has started giving trouble .... normal thing after a few years running for projection televisions ...... could be that the convergence IC's are getting too hot (two big IC's on a heast sink bearing an STK number on it) or that you have some loose soldering that needs to be resoldered on them.... worth the check
or have your power supply circuit board checked, if nothing seems wrong trouble leads to your horizontal deflection circuit board.
regards

Mits 55908 Convergence problem


Good Day, John;
It sounds like the Convergence IC's have poor solder connections, by re-soldering the convergence output IC's should solve your problem. The IC's are large and mounted to large silver "heat sink" with STK 392 # on them. Good Luck, big IRISH.

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.

Three colours don't converge


Shrink, the convergence circuit needs to be repaired, Until someone gets in there and takes a few measurements it`s hard to say what the cost will be, may just need to be re-soldered, good luck, BMW Rider

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.
