hi
i am having a problem with my SV3000w samsung vcr (world conversion model)
on playback of recorded tapes there is a sort of tearing sound on the
audio... i have cleaned it using a scotch headcleaner but no improvement, it
is only in playback in other vcrs that the problem is evident, most of which
flip between mono and stereo to compensate, the vcr itself plays back self
recorded tapes fine.. would appreciate any advice as to what the problem is,
if it's something i can fix or likely cost of repairs..
Thanks!

This sounds like two possible problems: either the tape path alignment
of your machine is out (especially the A/C head) OR the video heads
are not as good as they used to be and are putting down a weaker
signal. I think this is due to inadequate penetration of the tape by
the head chips.
Problems in the high band audio are usually the first sign of wear.
You often find that self-recorded tapes are Ok but other machines
don't pick up the audio tracks well.
Cleaning tapes are a waste of time - they don't clean the tape path,
they smear the dirt around and can redeposit it later, and many are
abrasive.

If a proper cleaning does not solve this, either replacing the upper
head assembly ($$$) or time to buy a machine are your options
good luck, B
