Zenith "Panarama" System 3 Help

[zenith2134]

Hey there jstout. Nice set indeed! Like those alot.

Last '79 I picked up would go red intermittently. I re-flowed the solder joints on the crt base board and also cleaned every single module connector with 91% rubbing alcohol. Along with cleaning out the service/user controls, this may be all it needs. I have probably 'fixed' 3 or 4 80s system 3s this way in the last few years. Good luck! (P.S. I'll look for those boards but they don't ring a bell...)
