VCR part identification - help !

[[email protected]]

Hi, my toshiba VCR started having 'muffled sound' problems
when recording (and to a lesser extent while playing back).

When I checked out the VCR I heard a piece rattling around !

I opened up the box and found that a small part had come loose,
it looks like a part that acts as a tape guide, it has a metal spindle
attached to a plastic part.

The part does not appear to have broken off, it seems intact, but I
cannot see where it has come from. There are no other parts that look
the same as the detached part.

I've put a picture of both the detached part and the inside of the VCR
mechanism on my web page. If anyone can identify what the part is and
where it has come from, I'd be really grateful. The VCR model is
Toshiba V252.

Cant say from the pic where that is from, but you could always load up
a tape and check if it passes over the A/C head with no creasing. From
there, you may be able to aork out what part of the tape path is
affected and give you a clue as to the location of that part.

Often the pinch rollers in these units get hard, drag the tape
improperly and cause poor audio.
while you're in there, you may want to do yourself a favour and remove
that stupid 'auto head cleaner' foam and arm near the head drum. You
could save yourself problems later!

Strange but from that photo how does the tape lace between the capstan and
pinch roller?

When you load the tape cartridge, the tape lands between the two. Then as
the tape is loaded around the head, the pinch roller comes down to contact
the capstan.

Looks like it might have broken off the main chassis just to the right of
the A/C head.
That's the tape-head looking thing to the right of the video head drum.

Still. can't tell for sure.

From your photo of the chassis it looks like the spring loaded finger
that applies the back brake pressure might be bent a little out of
square. As for your "extra" part, could you show a better in focus
picture of the bottom of the part? The end that doesn't have the metal
pin. I suspect that it goes near the audio head somewhere, but without
being able to see clearly the shape of the mount end of the part it
will be hard to figure out where it mounts on the chassis.

Floopy,
Without a better look at it, this is my best guess...
It looks like a tape guide, and it probably goes between the
capstan and the CTL/audio head stack. Note the white plastic
area at that location on the deck. See if the plastic on that
broken part matches up to the white area on the deck... bet
it does. The metal guide should stick upright & the tape
should ride on the lower edge of it at the rim. Super glue
-might- hold it, but why did it break off in the first place?
Cheap VCRs (most of what is made now) have plastic parts
extended through the metal chassis with little or no
reinforcement. It doesn't take much to break it... oftentimes
it just pukes all by itself. If that is the part that broke
off, the tape will likely skew off the audio head.
You have nothing to lose by attempting a repair. After
gluing it back, reinforce it somehow. I'd use a hot soldering
iron to heat a piece of wire and press it through the plastic
to beef up the weakened area.

Thanks everyone for your input. Ray and Mark - I came to the same
conclusion myself after a lot of staring at the mechanism !

The confusing thing was that there was no obvious 'hole' for the part
to
slot into, or to attach to another part of the mechanism. I decided the
only place it would fit was on top of the metal plate, below and to the
right of the audio head, where there is a depression in the metal.

There didn't seem to be any glue on the plastic part, so I don't know
how it stayed on in the first place (it's not a push fit) but I
superglued it in place, and now everything works fine - sound is stable
on both playback and recording.

thanks again folks,
