Hi, I wonder if someone could help me diagnose what is going on with this player. If I put slight pressure on parts of the inside it will get a picture but otherwise, the image will be heavily distorted. Sound works. If I turn the TBC off I get no signal at all. here are some images. I have highlighted the area in yellow in which I can get an image if I put some pressure on it.

I have tried aligning the p2 and p3 posts. The best I have managed to get is a good signal with TBC on then any slight movement of the VCR it will go back to the previous behaviour. I have also tried tightening the p2 and p3 posts but this seems to get me no picture at all.

Would an oscilloscope help me here?

Any help would be much appreciated.

Hard to say. Possibly the cassette is not sitting all the way down on the VCRs pins. If so this must be fixed. Adjusting the guides won't fix this but only make things worse.

Thanks for your reply. I'm currently reflowing solder joints. I've done what is visible from the top of machine. This has not seemed to have made any difference. I'm going to do the back next.

How would I go about doing what you suggest might be the issue? If I gently push the tape down it does nothing. It's only when I play with the bracket that I sometimes can get a picture.

So I thought I found the fault but my issue still persists! I found a cracked solder joint as shown in the photo. I now wonder if I have gone so far out of alignment, I'm struggling to get it back. hi-fi audio pops in and out when trying to align.

Yer it was bad light and my phone could not focus on the small pins. I repaired the break. I'll take another photo of the repair in better lighting

It is the far left pin that had a broken connection.
