Re: Convergence IC equivalents
Please do not duplicate your posts. Your duplicate was deleted.
Your set is a Pioneer. The kits listed by chassis number are for Hitachi sets only. You can use the chips from them in some other sets, but the kits are specific to Hitachi. I do not recall which IC your model had specified in the original production, but Pioneer moved to replacing all STK392-110 chips with the -180 at some point. If your set was serviced, or if it had the change in production, it is the apropriate part. What parts distributor did you talk to?
I have used the STK394-160 from the Hitachi kits in Pioneer models, but they are getting hard to find. I would just replace them with the -180 from a quality supplier like Acme or B&D. Be sure to follow the information in the convergence repair sticky and checkthe resistors and fuses.
Also, you should be aware that Pioneer sets are notorious for bad solder connections throughout, and simply moving boards around can break a weak joint. Your immediate problem may relate to that as well. We rarely service them that we don't start with resoldering hundreds of connections before bothering to troubleshoot them.
Looking for me, just google my username. I have used the same one for most sites for many years.
