Probably a LA7651P or LA7651K - the datasheet is buried in the LA7655 data.
The LA7651P was two sets in one - ground a pin and you "lost" features. Wildly popular in many low-cost brands - my notes show a Citizen, Sansui and Curtis Mathes chassis all using the chip. The Curtis Mathes chassis is the first after they jumped ship from Mitsubishi/NEC.
Consolidated Electronics in OH sold the chip for $2.88 in 10 qty....in 1998. I can say we never replaced one, nor a flyback in those Apex sets. Most junkers were dropped sets or lightning strikes, else the repair was a cap, a SMPS quick-fix, or a LA7835/36 Vertical output chip and cap swap. 88 dollar sets don't get a lot of investment in them. You can find used remotes on fleabay, but anything else, and you are looking for a donor set. Even when they were new, Apex skirted the FTC support rules by keeping production numbers low. When they hit the threshold, they changed models or model numbers, just to avoid having to support the chassis. They weren't unique - AOC, Bohsei and Tatung all did the same. The only Apex manual I've ever seen was the one for their earliest DVD player, the one with player-side indexing and region swap, and the "manual" is only three pages, mostly in Chinese, with only the part numbers and encoding systems being in English. |
