See attached photo of what convergence board in your set looks like and
the chips that fail; it is directly behind front panel beneath the
screen--access from the front.
I can tell you exactly how to get at it and what is involved in the repair---TOTAL PARTS COST ON EBAY will be under 25 dollars.
If you want assistance and this information and the photos helped you rate this solution as very helpful.
I have done dozens of these sets with the same problem.
