Convergence problem... Could it be bad solder joints???
I have a Sony KP-61HS30 rear
projection that is having intermittent a convergence problem. It will usually
straighten out if the TV is left on for awhile. Lately its taking longer. Sometime it turns on and the convergence is fine.
Originally when I looked up the problem, I found information stating that they
had a problem with the solder joint due to lead free solder currently used and that it was
pretty simple just to re solder the joint on a specific board. So now that I am
looking to try to solder the joint repair, I wanted to find more information, but now
everything I am reading is telling me to change the convergence ICs. Please
help me understand if the problem is the chip, or the solder joints. Thank you.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Convergence are daed.Have tools,lilke soldering iron,solders,solder wicks? Must know how to solders?Must repalaced 2 STK convergence ICS,some or all it resistors.Tries websites Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300-350 for parts and labors.
Hi, It would be great to assist you in Sony convergence issue. As you said, for some time TV shows bad convergence in picture that shows its matter of lose/ dry solder joints in D board, specially on convergence out ICs pins that need to be re-solder. There are 2 big black ICs mounted on aluminum heat sink on D Board of TV, below image shows D Board location in TV. Resolder pins of these 2 ICs and also check any other dry/ cold solder joints in circuit board. I do not think of IC replacement as problem occurs some time. Let me know if you have additional question. Thanks.
Seems TV has dry/ cold solder joints (loos connections) in convergence out section. Please check cold/ dry solder joints in convergence out section in TV, specially on pins of convergence out ICs. resolder these solder joints and all would be fine.

. If you see your symptoms you have a problem in your convergence amplifier circuits. Typical Sony Convergence repair requires disassembly for replacement of 2 ICs, sometimes a fuse or 2, then TV is like new.
It is much more complicated than changing batteries on your remote. Many consumers try unsuccessfully to do a convergence repair. I recommend finding someone competent to do it for a reasonable price. Typical repair shop charges may be from $400 to $650.
If you are in the Calgary area, call me. More reasonable rates.
When one or all the colors are bending severly, then the convergence circuit is not functioning correctly and must be repaired. Only one color bending means just the convergence ICs and all colors bending means convergence ICs and voltage supplies.
Convergence issues are the most common problem with rear projection (w/picture tubes) televisions.
The cure is replacing the convergence IC's. Sometimes the pico fuses need replaced as well.
If you have the experience to use a soldering iron and a basic understanding of electronics, then, you may be able to do this job. If not then call a servicer in your area. Go to the Sony website, Sony.com, and you can locate one in your area.
