So I take the top off, clean up the head and internals, test it out. Picture is perfect now. Put the cover back on, and picture is back to messed up/streaky. What is my malfunction?

Edit: thanks guys. Seems I just had to beat the distortion out of it. Note I can enjoy some poky little puppy.

Check for any cables that might be getting compressed between the cover and other parts of the VCR transport, especially the cables that carry the video head signals. Also check for anything that is rubbing on the flying video head that could be slowing it down which will cause a video output like you describe.

It's meant to be a convertible VCR; leave the top down.

Must be some cold solder joints the cover is pushing on the PCB where they are located.

Remove the cover, play a tape and gently tap around the PCBs with the back of a screwdriver. You’ll eventually locate them.

No comparison intended, can’t help but associate percussive maintenance with the character.

Grounding something that shouldn't be grounded? Check to see if the cover is touching anything it shouldn't be.

Hard to say, can’t really see under the cover once it goes on. Maybe…

an intreresting problem i encountered recently was a keyboard that only malfunctioned in it's metal case. I separated the screw contact points w/ a lil electrical tape where the board screwed in. Long story short the case itself was creating a grounding problem of sorts.

Back side of the casing is a little snug, putting pressure on some component in there.

Is the cover putting pressure on something?

Don’t know, can’t see when the cover is on. Maybe I’ll take the glass out of the China cabinet my wife wanted and now doesn’t want and make a glass cover for the thing.

Well no, you could just kind of eyeball what’s making contact when you’re putting it on and see if something is out of place, loosen up screws when you reinstall the cover, etc. just an idea. Good luck.

I got it. Put the cover on and smack it around a bit till the picture clears up.

Start a tape playing with it open, then slowly put the cover on and watch the TV until it has problems.

Just needed a bit of the old percussive maintenance.
