I just recently got hold of one of these in what looked like really good condition, on the outside anyway.
Got it all set up put a tape in and got no picture but sound! machine is making a right squealing sound as well when playing a tape then gradually stops.
I jogged it forward slowly the picture played, soon as I removed the video and put another one in the same thing happened no picture but sound. I tried a few tapes and it did it with them all.
Put a couple of videos up of the picture issue and another issue when trying to eject the tape it makes a right clunking sound then it will either stop making the sound then shut the machine down.
Check the videos here, sorry about the quality they were taken with my tablet

I am returning this item because I can't find anywhere at the minute who can service it for me, the seller has accepted my return. Just a bit unhappy because the machine looks in really great condition.

Think I may have found the issue I was seeing

It looks like an issue with the bottom of the head drum overheating after several minutes, the seller wouldn't have noticed this when just testing to see if it worked. I have guided the seller to this topic so I do hope they get it repaired in the future.
