convergence problem expect to pay around $300

Problem seems in convergence out section.

TV needs Convergence Out ICs replacement.

If you have TV repair experience and know good soldering work then you can give it try OR get help of qualified TV tech to fix it.

If you need further help, let me know.

If the convergence controls don't fix the issue then the convergence circuitry is most likely faulty. A Toshiba repair center will be able to get you an estimate for repair.

i think you need a new convergence board they rin from about 88.00 to about 140.00

yes you just need two ICs

Repair involves some dis-assembly...replace convergence IC's
and inspect current limiting resistors for over-heat damage...
part # STK392-110 sub to upgrade STK394-160 Hitachi part # CZ 01341....you will need two....good solder technique required.

The Samsung has bad convergence IC's most likly. This should be repair ONLY by a trained technician as a TV set is not a place to experiment or tinker with because of the extremly high voltage inside. This repair should cost you in the range of 250 to 400 bucks . Good Luck
