Problem is called convergence; see attached photos.
This set uses 2 of the STK-392-110 convergence chips, both will have to be replaced and total parts cost on EBAY will be under 25 dollars.
The good news is I have start to finish step by step instructions for this repair in this set. They tell you everything you will need and exactly how to do it.
They are based on my experience doing this repair in hundreds of sets just like yours.
I will enclose also a photo of what the chips look like.
If you want the instructions let me know and we will find a way to get them to you for free.
If this information told you something you did not know, rate this solution as I do this here for free.
This is a JVC board but it uses the exact same chips (black) that are in your set.
