Question about Televison & Video
My sony kp-43770 tv red and green color will not align with focus botton
Model number does not sound quite correct but if a convergence problem both chips the set uses will have to be replaced and the set adjusted with the Sony remote.
Confirm actual model number and Google it with "parts" to see what it uses. Most convergence chips will have the actual STK number right on the front of them and almost all Sony sets use two chips.
typical chip used in some later Sony sets

You have a convergence problem. Here are some of the most common symptoms.
Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in but stationary.
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.
You need to replace the convergence chips and convergence resistors.
Check the site www.TvRepairKits.com.
They have put together a kit for your exact model. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself.

you will need to replace the two STK392-560 ICs and also check the 4.7 ohm 1/2 watt resistors and the six 3.5 amp pico fuses.
