Replaced two Convergence IC in my Panasonic TV. it looks alot better then before, doesn't have that 3d effect anymore but can't get the color blue to aligned tho. I Did the setup menu "convergence 2", the top right cross hair blue aligned but the rest wouldn't. Could it be somthing else i need to look at?. Is the CIC is the only thing in my tv that converg colors?. Please Help.

One of the resistors in the circuit connected to one of the ic's has burned out or changed value due to heat caused by short in previous ic before it was changed.

This is a convergence output IC problem. convergence board (main Board) would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300

Picture double colored or 3D looks is due to failure of convergence out ICs in TV and need to be replaced.

Screen looks like 3d

While Ginko's solution is correct, it is possible that the problem is simply poor solder connections at the ICs. If you can solder, try resoldering the pins on the ICs first. That may resolve the problem. Please note that there are potentially dangerous high voltages present even when the set is unplugged.

Also, If you post the model number, we can provide you with the part numbers etc.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.
