You will have to post the make and model number of the Audio system before any expert can tell you that.

How can I find the part number to order a Vertical Output IC for a Sansui Model tvs2746a


The vertical output IC will have a number printed on it. You mus send this number to get a new one. Normally, all vertical ICs are available from local electronic spare part selling shops. It is not a difficult to get component. Won't cost more too.

Convergence is bad on left side...good on right.....where convergence is good the picture is great


Hi,
Re-solder convergence output ICs pins and nearby big resistors that might solve your tv picture problem and if that does not help then replace both convergence output ICs to fix the problem.
Convergence output ICs would be available in local repair parts shop or google it.
Thanks.

This problem is due to convergence output ICs failure and both chips will be replaced to fix the issue.
There are two big black ICs installed with aluminum heat sink on deflection board, these are convergence output ICs and will be replaced to correct the problem, it is common problem of rear projection tv.
Below image of deflection shows ICs (marked in red) that are need to be replaced.
IC number is STK392-110 and available with Part Store for $32 each.
Click above link to see an image of IC.
If you are handy with electronics stuff repair and can replace parts in tv circuit board then can replace these parts yourself or ask local tech to help you.
Hope these info will help you.
Let me know if you have additional question.
Thanks.
