Check here or here and do a search on the part you need. I would suggest that before changing those ICs you check the micro/pico fuses near where the ICs are connected as well the low values resistors.
Good Luck.

I have a Toshiba rear projection TV model # 50H71 for about a month the tv would randomly pop off (lose sound and picture) for about 45 seconds and then come back on now th picture is reduced in size by...


Good Day,
The TV has a convergence problem; the IC’s for that circuit will need to be replaced. The cost for this repair runs around $450.00 or more.

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 as
shown in Figure 2. Replace the Convergence Output IC’s using the “T”
type version Part Number 23135090 (STK392-110T).

Thanks for choosing FixYA, Big Irish

Replace the convergence IC's - P/N STK192-110 with part STK192-150 or 180. Then you can go back in and make the detailed convergence settings and get your picture back in alignement. Also check the flame-resistant resistors around the ICs to make sure that none of them have opened up.
