    One of the two convergence chips this set uses is bad. Both will need to be replaced and total parts cost (if purchased on EBAY) will be under 25 dollars. If you are handy and can solder it can be a do it yourself repair.

    I will attach photo of what typical chips look like---should have STK-392-110 NUMBER PRINTED ON THEM IN WHITE---look for heat sink in your set and ID which chips it uses---in Hitachi most are usually on right side as you look from back.

    Do not forget to give very helpful rating as I do this for free.
