Mitsubishi HS-u53 VCR has jerky picture
 

I'm having trouble with a Mitsubishi HS-u53 VCR. For the
past couple months, sometimes when putting a tape in the
VCR, the VCR would shut off. After powering it back on, the
tape would be ejected. Pushing the tape back in would
usually work and the VCR would play. Sometimes the VCR
would shut down again, but powering it back on and pushing
the tape back in would work and the tape would play. Last
week was watching a tape, and the VCR shut off. Turned VCR
on, after a couple seconds it shut off. After trying this 3
or 4 times, the tape ejected from the VCR. Now when I try
to play a tape, it plays, but the picture jerks up and down
and about every 5 seconds the picture disappears and all
that's on the screen is static. Also, the data counter
stays at zero. The idler assembly had to be replaced about
7 years ago, I thought maybe it was giving me trouble again
(although the last time, tapes wouldn't play at all), so I
opened up the VCR to check, but the idler appears fine. I
can't see anything else that appears broken (I didn't really
look too closely, though). Anyone have any thoughts on what
might be causing this?

I'm assuming the U52 and U53 are similar. If that's not the case,
ignore this.

One thing to check is the main belt underneath. On my HS-U52, it
had become stretched and wasn't adequately driving the loading
mechanism. There are also lubrication issues but that requires
a major disassembly of the parts underneath the dexk and so far
I've avoided doing anything but they may first show up as squealing
rewind or FF.

I took the bottom cover off of the VCR to check the belt, and the belt looks
okay.
I took the belt off, and it doesn't look like it's stretched. I played a tape
with the
bottom cover of the VCR off so I could try to see if the belt was slipping, and
it
didn't seem to be, I couldn't see any slipping. Fast forward and rewind work
fine.

How would I check to see if either of these were causing the problem?

I would, but it might hit you in the head while you're scrounging for food.

Good retort!

P.S.

These Mits's also had pinch roller problems, and a juerky picture is
sometimes caused by the felt coming off the back-tension band (around the
left hub).
