Convergence problem you fixed on your Panasonic

There are essentially 2 boards in this TV. One has all of the high voltage stuff on it and connects to the tubes. The other has stuff like these convergence ICs and other electronics. While the boards are electrically connected, none of the high voltage lines run to the convergence board, so you should be ok.

To be safe, I left the TV off and unplugged for about a day before I started the replacement, but as you read in my saga, I didn't get it right the first time. By then I was pretty comfortable with the electronics and didn't worry about the high voltage lines. But take the obvious precautions like not touching things you shouldn't, and if you feel it necessary, maybe wear gloves.

The only other thing I can say to be careful of, is that the washers on the screws holding the heat syncs to the ICs will not come off, so be prepared to replace them after cutting them off. Also the heat syncs get really ot in operation, so don't touch it after it's been on for a while.

Let me know if you run into any trouble. Set is still working fine a month+ after fix now.

Your TV most likely has a Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.

Solution #1

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.
