This set uses two STK--392-110 ( you can also replace them with STK-392-150 which is a upgrade for the original 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
