Funai/Magnovox/etc 13" combo unit

[jakdedert]

Someone (Patch?) answered a post from somebody who had one of these which
was shutting down spontaneously; with a query as to whether it sounded like
the tape transport was trying to cycle before it did so.

The OP's unit didn't fit the symptom, but I have one which does. I posted a
query in case this was a common fault with a specific cause, but never got
an answer. If there's something common to those ubiquitous units which
cause this symptom, would someone post it and save me a bit of troubleshoot
time? If needed, I'll post the exact model, but apparently these are so
common (actually I've got two identical ones with different brands &
#'s--both dumpster finds), and sold under so many different brands that most
of you seem to be familiar....

Again, the symptom is that the unit powers on with a picture, the vcr
mechanism tries to cycle--although no tape is inserted--then it gives up (or
binds up) and shuts down. Obviously something is out of time, or a switch
is closed which should be open...mode switch?

Anybody?

A possibility is the loading tray out of time, usually from someone forcing
a tape in, the tray comes to the full unload position before the mech
reaches the "Home" state. Try removing the loading basket assembly and
letting the unit reset, then reattach the load basket. This works with some
units, your mileage may vary.

Depending on which model you have it could be a couple different things.
If it's the model with the loading belt on the side of the VCR, that belt and
the one on the bottom of the VCR are bad and the mode switch needs it's solder
connections resoldered, and the mech needs to be manually reset to the correct
timing.
If it's the model with the short loading belt on the very back of the VCR, it's
either that belt is bad, or the center sensor LED is bad or dirty, or the prism
is broken off from a tape being eaten.
Hopefully this all makes sense to you,
Ron

Thanks, Ron. I've seen enough queries about these to know someone would
have direct experience with them. I was hoping to get 'very' specific
advice...all of the above will be investigated, of course. A 'slam-dunk,'
open-it-up and fix-the-exact-issue, with little or no troubleshooting would
have been great; but....

Thanks again.

Wow, I have RCA 13" TV/VCR combo with exactly the same problem!
VCR mechanism is clicking, then the unit shuts down. I took it completely
apart and found that one plastic piece went completely off the wheel that
was supposed to drive it... Just need to figure out how to put them back
together for proper timing...

Strange?? I have a Sylvania Version that will not produce any video in
either the tele or vcr modes. Finally found a web database printout for that
nice "TV on a chip" IC developed by/for MGA with appropriate pinouts. After
deliberate signal injection, signal tracing, etc. I also concurred that
indeed it was very probable that cursed IC. Since all appropriate signals
going into the device are there and all the bias voltages are there,
however, the r,g,b outputs from that device is not produced. I could have
just asked for a comprehensive, tongue-in-cheek, shoot me if I'm wrong, what
is exactly wrong with this device. But, as a competent tech, followed the
true troubleshooting precepts and diagnosed the symptom, divided and
conquered the item, and found the accurate cause. What is wrong with this
picture?? Database information is available, either from the manufacturers
or supplied by Technical Forums. Having someone bluntly flame another
because they are not available to diagnose and repair is absurd. That is
IMHO!!! Cheers

Eugen, to whom are you referring--regarding a 'blunt flame?' If it is me,
that certainly was not my intent...rather a heartfelt 'thanks' (stated
twice) for the info I did receive (with a bit of wistful regret that it was
not more specific). It should help with the diagnosis/repair, and save me a
bit of time on this 'so cheap as to be almost not worth repairing' piece.
It'll keep it out of the waste stream a little longer.

Do you prefer to spend more time on a cheap piece of gear than necessary?
This thing sold for maybe $125 new, and would be worth around $25 at a yard
sale in perfect condition. How much time/research would you spend on it? I
was under the impression that it's why this forum exists....

If I offended anyone, please accept my sincere apology. Again, it was not
intended.
