I don't have the service manual. If someone happens to have a copy and could upload it that'd be amazing.

I've submitted it to the database. Good luck. Hopefully now you can fix it! :thumbup:

I ordered an oscilloscope, hopefully when it gets here I'll be able to do some more serious testing and diagnostics. Although without the test disc I can't do most of the alignments in the service manual. If all goes well I'll be able to solve the issue and post my finding on here, then several people will have working players again, including me!

Yeah the test disc is more important than the scope. Also save your self a lot of trouble and buy a used analog scope.

I've noticed that 95% of the tests need that special disc, my guess is the disc alone costs more than a new player. I ended up getting a rather nice Hantek DSO5102P, it's a very nice and very capable $260 scope. Since I plan on using it for a slew of other projects I wanted one with as many features as possible. Getting a new one has far more benefits than getting an old one most notably it'll be much more reliable/accurate than a 30+ year old scope.

It is about $100 shipped for the disc from PacParts.

My Tektronix DSO can have trouble seeing some of the waveforms. Persistence mode helps but still not as clean as my analog scope. I'm far from an expert with scopes, so I could just have something set wrong.

I'm in the same boat, this would be my first ever scope. Thankfully it has a button to automatically set everything and an XY mode to mimic and analog scope. I know Tektronix makes really nice stuff, would you happen to know what model you have? The one I got was really a spur-of-the-moment type thing and I don't have the extra to get the disc too, I'll just have to do what I can and hope for the best..lol

My digital one is TDS 2014B. Someone was selling it for 1/4 of what it sold for on eBay so I scooped it up.

My analog one is an ancient Hitachi on its last leg. I'm looking to replace it with one of the later generation Tektronix. The older analog scopes can indeed be sketchy. This is my second cheap find and the X channel does not function properly. I'll try to clean the switches again at some point.
