This set uses two STK--392-110 type convergence chips----You can buy both on Ebay for less than 13 dollars plus shipping. Both chips need to be replaced and any damaged resistors around them located and replaced also--most of the time the set just needs both chips replaced and then adjusted.

If you cannot do this repair yourself--look in your area--most shops TRY to charge 300-400 for this kind of repair----I do lots of them here--did two Hitachi sets with this problem yesterday for 200-250 total.

MAKE SURE WHOEVER you get to do this changes BOTH CHIPS--SOME techs will come out and just replace one--in a short time the set will have the same kind of trouble again---Now is the slow time of year for TV repair shops---shop around for someone who will do this repair IN YOUR HOME--almost any good tech can do it in about 1 hour---if they say it "has to go to the shop" keep looking.

The chips are black(2 1/2 inches wide and about 1 1/2 inches tall with 18 pins) and will have the STK number printed on them in white--they are located on either one large metal heat sink with fins or two smaller heatsinks that are side by side.

Ghosting


Hi,
This sound like a convergence problem and maybe another problem for the pink symptom. I would not suggest to do it yourself on this one because after the IC's are put in and sometimes a resistor or two there is also a very extensive alignment that could occur. Just off the cuff have you pressed the magic focus button on the front? If magic focus don't fix then the convergence is bad . Suggest a good tv repairman.
