The convergance is located on the ssb board part #313503712271 but it might be cheaper to replace the convegance amplifiers and the resistors. the amps are STK392-120 the resistors are 6.8 ohm 2watt and 10 ohm 5watt. there are 8 of each starting with location 3149 to 3166. check them with an ohm meter to see which ones are open. there may be visible scorching of the bad resistor.

Screen plays double


It is called convergence out IC failure and you need to replace 2, ICs in convergence section of TV.

If you are familiar with TV repair or can solder electronics parts in circuit board then let me know exact model number of Panasonic TV to guide you more with technical info or call local TV repair shop for repair.

Rainbow effect at top of screen


This is a convergence problem that can be as simple as poor solder connections on the pins of the convergence ICs or defective ICs. If you wish to attemp the repair yourself, please let me know and I'll look up the parts and provide additional details and instructions. Also, please confirm your model number.

Thanks,

Dan

Bent picture


The convergence circuits straighten out the edges of the picture, putting the 3 colors exactly where they should be for the picture to look normal. There are usually 2 large IC's that handle the 6 convergence channels and if one of them burns out then one of the colors bends dramatically. If the power supply for the convergence circuits stops working, then all 3 colors bend in, the colors do not line up with each other and the image looks almost 3D, and the adjustments in the convergence menu will have no effect. I would bet that is the case with your set - the convergence power supply has quit working. If you do not have experience troubleshooting power supplies and realigning convergence circuits in projection TV's then allow a qualified tech to handle it for you.
