VCR sound anomaly

K

Kevin Hollings

Guest
I have a Hitachi F362 VCR (coax in from cable, coax out to TV). It's a few
years old, but works just fine--until now.

There is a problem with getting incoming sound to the TV--the volume is very
low. However, no problem with sound when playing pre-recorded tapes. I
checked it with different cables and TVs, with the same results.

Anyone know where (aside from a repair shop) I should look for the problem?

Thanks for any help.

Kevin.

Hello, Kevin,

I repair mostly the Philips recorders. Usually this symptom indicates a
bad
pinch-roller.
I would replace that part, to begin with.
Of course, since the set is open, clean all the heads.

Succes,

Alain

Thanks, Alain, for the note.

The problem occurs even without a tape in the machine, though. In other
words, even when I'm watching the TV 'through' the VCR.

Must be the 'something' that conveys the sound to the TV-out jack...

Sorry, Kevin, I misunderstood this.
Disregard what I wrote :-(
Something else of course but I'm not acquainted with that set...
You wrote that it DID work, so it must be something in the sound
circuit if you did not change the cables, the connections I mean.

Bye,

Hi Kevin,
I have the F462 VCR. Can you elaborate a bit on the problem? Does the audio get
into the VCR ok even when you are not taping (ie. the audio display bars move)?
Does it do the exact same thing if you use the audio input to to VCR as opposed
to the coax? Mine was doing it only on the coax and I found the MTS module was
bad. I replaced it with two capacitors and everything was fine again.

Make certain that the VCR tuner is NOT in the SAP mode.

According to the settings on the VCR, SAP mode is <OFF>, although the
letters SAP appear on the display of the VCR.

When I connect my CD player to the L/R audio in jacks on the VCR, the volume
levels are normal. But as soon as I reconnect the CABLE coax, the L/R
channel levels don't work properly (both levels show just the first block,
instead of moving up and down as would be expected), as though the sound
isn't getting in.

Lawrence: Does this sound identical to the problem you had? If so, how easy
might it be for me to find/replace the MTS module with capacitors as you
did?

Kevin Hollings:
To just blindly replace a module and other parts without FIRST performing
even basic technical troubleshooting and testing could easily be a waste of
money and time. While certainly the MTS module could be suspect, there are
lots of other faults that could be causing the symptoms you reported in your
original post.
A service shop that regularly repairs VCR's should be able to provide you
with a repair cost estimate so you can make an intelligent repair decision
with facts.

Sounds pretty much like the same thing. You can check out this article to show
you how to bypass the module for troubleshooting.
http://www.iwaynet.net/~nesda/SonyAudMod.html
If you go on Google or some other search engine and do a search on SBX1637 you
can get the data on the little module itself. The module is about 1 inch square
and has a bunch of capacitors on it that end up leaking. You can see the black
leakage quite easily on its board.

Thanks, Lawrence. I'll take a look and see what I can do, and let you know
how it turned out.

Also, thanks to Daniel for sound advice. I don't have a lot of money,
though, and recently paid a 'service center' $250 to 'fix' problems with my
CD player and amplifier. You guessed it: I'm out $250 and my machines still
don't work.

Thanks for everyone's help. :)

Kevin Hollings:
Just about ANY repair shop owner will tell you that if you paid $250 to fix
problems with your CD player and amplifier and the machines still don't
work, you NEED to TAKE THEM BACK to the shop so they can MAKE IT RIGHT.
You at least owe them the chance (and yourself) to get if fixed right or get
your money back...... unless you have waited way too long after the repair
was done...... it is like having a meal at a restaurant that isn't
right...... don't complain weeks after the meal was eaten and tell all of
your friend how bad the food was and that you will never go back.... give
the restaurant an opportunity to correct the problem.
After all, the goal of ALL businesses is to have repeat customers and good
word of mouth advertising from satisfied customers. We can not make a
living on "one time" customer relations. We are not all crooks, we want to
do a good job for a fair price...... you won't see any Cadillacs, Mercedes,
or BMWs in the owner's parking space at my store.... just a 10 year old
service van that needs a paint job and a new motor.

Daniel,

My apologies. I didn't mean to tar all repair shops with the same brush. I
simply meant that I didn't want to be charged again for the same problem,
and add to it the amount of time it takes me to go there and back, and wait,
and then go there and back, plus parking, etc.

Having said that, you're right, of course. I'll give them a chance to make
it right.

Kevin.
