Beocenter 7700 Issues

[Imax5353]

Hello everyone, I just snagged a Beocenter 7700 that has issues, and just wanted to check here before I delve too far.

So, it power on and the main display shows, however everything else is dead, the P6 dial lights up, but not the tuning or stereo indicators. The phono doesnt move, but it recognizes that there is a record and even the phono light is off. The tape sensor and light work (couldn’t test mech as the belt is goo).

Any advice would be great. I was also wondering what the 15 v, 20 ma port next to the speaker connectors is, almost looks like a DC plug, is there supposed to be a fuse?

 

Thanks!

The processor check shows P O, so I’m assuming its good.  I’m out of town, so should be able to get a look at it soon.

After getting a good look, and waiting for parts, someone had been in there before and replace a few of the caps.  I replaced the powerboard caps and rectifier, hoping for the best, but no dice, and also discovered that the board has the wrong polarity on one of the main caps (POP!).

So still some digging to do.
