SET USES TWO OF THE STK-392-120 OR -110 CHIPS.

It can be a do it yourself job with some advise--best way is to look inside first.

As you look from back of set (set unplugged and back cover off) they should be side by side on two metal heat sinks with fins to the far left.

Take a look, they will have the STK number printed on the front of them in white. Also take a look at all the tiny resistors near the front on (in front and to left) to see if any of the resistors are white in the middle--the resistors are easy to test.

Total parts cost if purchased on EBAY (I know a seller there) will be under 25 dollars total.

Chassis (plastic which contains the boards) needs to be up in the service position--best way to get at everything.

I have repaired hundreds of these sets and know what to do and not to do.

I will attach photo of typical convergence chip so you know what to look for--chips have 18 pins each.

If this told you something you did not know rate this solution as very helpful and I will be here to assist you.

Here is what the chips look like, it is from a JVC but yours uses similar parts and they should have the STK-392-120 NUMBER ON THE FRONT OF THEM. Photo here also shows protect resistors in front of the chips, in your set they will be somewhat smaller and usually light green in color.

Call a technician to recalibrate your color guns. They usually need to be recalibrated yearly, lately. Many times the cost of getting it service exceeds the value of replacing it with a new one.
