Sony TV -- some remote functions don't work

I have a Sony KV10FMR20, little color portable with FM, only some of the remote functions work. Can't adjust any picture or setup functions except tint. Tried another remote, same problems. Any suggestions? Thanks, radio-active.

Weird. First, hard reset it

Weird. First, hard reset it by unplugging it for about 4 hours, then plug back in and try again.

I'll try that, but I'm not

I'll try that, but I'm not optimistic. The set was unplugged for weeks recently. If anyone has the SAMS for this set (in folder 2887) please help me out. I'd like a scan of the schematic, especially any pages related to the IR receiver, controls area, etc. Thanks, radio-active

As I expected, unplugging for

As I expected, unplugging for several hours did not help. I suspect either a microprocessor problem, or an IR receiver problem. Having the schematic or service manual would help me diagnose this. TV was an estate sale buy, so I'm not going to sink much into it. Still works fine, just annoyed at not being able to adjust anything (except tint). I haven't hooked it to cable yet so I'm not sure if I'll be able to get it to recognize all the cable channels. Any help getting the documentation greatly appreciated -- and compensated.
