Check all wire connections again inside, especially the motor to eject the tape.

    Hey!, I found the problem when you said "broke the small connection board for that motor"...because I said "especially the motor"...so why the low rating for the solution...almost there? I think not. I think "problem solved".

I GOT THE TAPE OUT, BUT THE ARMS WILL NOT RETRACT?


The mechanism of a VCR is very complex. The incorrect removal of a tape will not only have caused the tape arms to be out of sequence, but also caused the electronics to be confused. Inside the VCR is a device called the Mode Switch. This tells the electronics which position the VCR is in. This Switch rotates with every movement of the VCR. When parts of the VCR mechanism are moved out of sequence to the rest, the mode switch will be in the wrong position. So the VCR electronics might think it's in the eject mode when parts of the mechanism are still in play mode.
If the mechanism was working normally the arms would have been retracted as soon as the VCR was powered up. So it's now out of sequence. Pushing a tape into the holder might cause the mechanism to reset, but I suspect that what will happen is that the VCR will either show a fault code or just power off. It does that to prevent the motors causing any damage when it gets stuck.
The only way to solve this problem is to have the mechanism set up in the correct way. This can only be done if you have performed the operation on several VCR's of the same type or have the service manual. The reason you need the manual is because it tells you how the different cogs, wheels and the mode switch need to be positioned. They often have holes are marks on them to aid in the set up. To make matters worse VCR's are rarely set up in the eject mode. Without knowledge of how to set up the video or the manual you will never get it to work properly.
One further thing you will need to check that the removal didn't damage any plastic parts. Plus clean the tape head and any surface that the tape touches.

VCR Stops on me


Hello Ro Power,

 

This might be due to the tape sensor malfunctioning. You will need a schematic, and multimeter, and a LED power meter to work on this problem. When the tape loads it causes an LED sensor to become blocked and then the sensor tells the control chip that a tape is present and the the controll chip allows the tape to continue playing, if the sensor does not work the signal never gets to the control chips and since other events happend and triggered the control chip the control chip looks at this as an error and the stops the tape , some units even eject the tape.

 

If you do not have a background in electronics, I would suggest that you take the VCR to a qualified shop and have them repair it.

 

I hope this helps,

Thank You,

VCR won't record, just ejects tape


You have not mentioned the make and model number of the vcr. Any way the problem is due to end sensor or related circuit. End sensors are photo diods which you can check the shorting with a multy meter.

VCR won't load tape all the way


Best to check the tape by comparing it with another tape. There could be damage to the case. Check that you can lift the flap at the front. If all else fails or you find damage on the case of the tape, the tape can be removed and placed inside a new blank tape case. The new tape reels would have to be removed first. It's a bit tricky, but as long as you dont touch the tape itself it should work fine.

I insert the tape and it stops and the power shuts off. If i turn the power on, it ejects the tape


This sounds like a problem caused by the Mode Switch. These in VCR's can cause all sorts of odd things. The switch can become faulty, or just get dirt in it. The switch tells the electronics of the VCR which position the mechanical parts are in. If the electronics get conflicting information, then it will power down the VCR. Another cause of a good mode switch to give wrong info, is damage to the mechanism. This throws out the timing.
A spray of Servisol Video 40 on the switch will restore a dirty one. The other causes are more tricky. Since the whole thing will need to be set up again in position. This will most likely require the service manual as most VCR's are never set up in the eject mode! After any faulty parts are replaced of course!!!

Power goes off when a cassette is inserted. Tried cleaning heads but it won't even run that. When power is turned back on the cassette is immediately ejected.


Good day!!!

Most common problems
  • VCR refuses to FF or REW and shuts off.
  • VCR shuts off entering PLAY or REC or at random during PLAY or REC.
  • VCR eats tapes.
  • VCR doesn't accept tapes or ejects them without cause.
  • Sound is wavery, fluctuating, or muddy.
The cause for all of these is very often a bad idler tire or other dirty, worn, or tired rubber parts

I find the codes of the lyrics of moments of truth by:FM static..


Moment Of Truth - Fm Static
Here we are, in the best years of our lives.
With no way of knowing, when the
whee’ll stop spinning cause we don’t
know where we’re going…
and here we are, on the best day of our lives.
And it’s a go, lets make it last, so cheers you
all to that, ’cause this moment’s never comin’ back
I used to know her brother, but I never
knew I loved her, ’till the day she laid her
eyes on me. Now I’m jumpin’ up and down,
she’s the only one around, and she means
every little thing to me
I’ve got your picture in my wallet, and your
Phone number to call it, and I miss you more,
Whenever I think about you,. I’ve got
your mixed tape in my Walkman, been so
long since we’ve been talkin’ and in a few
more days, we’ll both hook up, forever and ever
And here I am, on the west coast of
American and I’ve been tryin’ to think for weeks of
all the ways to ask you, And now
I’ve brought you to the place, Where I’ve
poured my heart out, a million times, for a million
reasons, To offer it to you
I used to know her brother, but I never
knew I loved her, ’till the day she laid her
eyes on me. Now I’m jumpin’ up and down,
she’s the only one around, and she means
every little thing to me

VCR picture


It has to be the machine or the TV. Have you purchased a new tv? The old vcrs seem to last forever and run fine. And if some of the tapes work and others don't, that is a bit strange. Is it the newer tapes that work?
