How do i fix my toshiba flat screen 57" tv when it looks like it is 3d


Howdy;
It sounds like the convergence IC's have failed.
Replace the defective Convergence Output IC Part Number 23905094 (STK392-110) using the revised “T” version IC Part Number 23135090 (STK392-110T). When Convergence Output failure is detected, it’s recommended that both IC’s be changed to the “T” type IC version. Inspect the Convergence Output IC’s for the “T” type version.

The only items on your set that should need replacement would be both convergence IC IC801 and IC802 which are both STK392-570 and you will also need to change the two 5 Amp pico fuses which are F9A04 and F9A05 they are both % amp pico fuses. All parts are located on the center Board

Tosiba TZ55V61 Convergence IC 150?s vs 110?s


STK392-150 can be replacement for 110's no other resister values need to be changed, however be sure bad resisters are replaced and check all the resisters (6) have been taken out of circuit and checked. also check for solder cracks and cold solder joints.
