Question about Toshiba MV13P3 19" TV

1 Answer

VCR Tape VCR is not working properly. When I put in tape to play it sounds like the forward mechanism is slipping. Starts to move tape forward then slips. Video is displayed very jerky and it sounds like someone is scratching a blackboard. Tried different tapes. It is the VCR unit that doesn't work. The television part of the unit is working fine.

Hi,

This sounds like the tape is being stretched which can only mean one thing, the brakes on the supply spool (left side) is engaged and is preventing free rotation of the spool for the source/supply side of the tape. A sure sign that tap is being stretched would be deformation on the edges of the tapes you have used (rewind them just a bit).

Since this involve opening the unit and full disassembly of the mechanical aspect of the VCR, perhaps your best bet would be to seek the services of a qualified VCR technician.

Hope that this be of some help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

My Philips model DVD750R/17 shuts off when playing a VCR tape after about 15 minutes. Why?


The most likely cause is a problem with the mechanism that moves the tape(when played a bit more weight is on the takeup reel.

Someone would have to open the unit so they can see the reels moving---watch to see if it begins to hesitate when further into the tape.

A trick that can help to see is put a fully rewound tape in and hit fast forward--let it go all the way to the end and rewind--if unit does not stop after doing that see what happens in play.

A worn drive unit that moves the tape can sometimes get better after run this way.

Close when play vcr


Problem in the mechanism that moves the tape in play,ff,rewind and also winds tape back into cassette and ejects it.

A vhf tape got stuck in the machine. I could see the tape itself was caught on some moving prongs. now i don't know the proper setting for the prongs and cannot get any vhs tapes to play.


Hi, if VHS tape is in you have only one solution..to disassemble DVD/VCR ..Can you do it ? you may try !!t
Here's how to do it..
* 1 Turn off the COMBO. and unplug it.
* 2 Remove the 4x screws off COMBO on the sides and take off the DVD/VCR casing.
* 3 Look for the Tape which messed up with VCR transport mechanism ,try to release tape of the transport with your hand..
* 4 Since EJECT feature works with power only ,while you keep the tape off from transport plug the device to power and turn it on..Don't worry,you will see the eject mechanism starts moving back on forth,keep the tape off it and let it eject..
* 5.When tape is out .If it destroyed badly normally you should not use it however if the recording in is valuable for you you can cut the chewed portion and
splice it back together .(Pls see the video included...How to fix a broken VHS tape.)
* 6 While it is open,place another Tape to see if mechanism works properly. and eject it...
* 7 Replace the casing and the screws. Plug the player in and turn it on. Now player is finally working ..
Hope this helps!..
Take care and please

I've a Mitsubishi HS-U770 that has not been used for several years. When I tried to use it today, the tape loaded but would not play, rewind, or fast forward (I hear what sounds like gears slipping). The...


Mine did that, and when I opened it I found that a small drive belt (visible from the bottom with the cover removed) had deteriorated into goo. This unit had been in storage a while and the rubber just deteriorated, I guess. The trouble is that now I cant tell what size it is, or what length. I think this belt drives the mechanism that loads the tape in and out, and the rest of the mechanism is triggered by the tape cassette moving into position. Since it cant get loaded properly, the rest of the machine doesnt work right, either.

I'm not sure how old your unit is but over time, the rubber parts in a VCR become cracked, glazed and begin to slip.

There is a rubber wheel about the diameter of a nickel that is called the pincher wheel and does exactly what its called.

It pinches or compresses the tape against a shiny metal spindle called a capstan. The capstan spindle is connected to a motor. The pincher wheel rests against the turning capstan with the tape in between the wheel and capstan.

The pincher wheel can become glazed and coated with a brown oxide that has worn off of the tape. This causes the tape to slip and it can spool out into the VCR.

There is another wheel called an idler tire. It lays flat and pivots between the sending reel and pickup reel. Its used during play, fast forward & rewind. This wheel too can become glazed and worn causing slipping. If your unit won't play, fast forward or rewind, most likely the idler tire is the culprit.

There are also belts that can also become glazed and worn. These belts are used along with motors in the tape load/eject mechanism and capstan drive. If the belts slip, the tape may not load or eject properly and the capstan might not be turning properly.

When I owned my repair shop, one solution was we to remove the belts and/or tires and apply a re-grip solution on the rubber with a cotton swab, while roughly rubbing the the entire rubber surface back & forth with the swab. The re-grip solution actually eats away the top surface of the rubber leaving the rubber surface course and causing it to grip better.

Another solution was to just replace all of the rubber tires and belts. These parts including the re-grip solution may be ordered through www.mcmelectronics.com

Please let me know if I may be of further assistance to you.

Good luck!

Rewind or fast forward


Though not familiar with this model, VCRs of all sorts have an idler mechanism which drives the supply and takeup spindles. Either the idler is somehow defective and slipping, and, assuming this idler is belt driven, the belt may be slipping just enough to cause a no Rew/FFW condition. If you had access to a test tape jig (a clear dummy tape, which allows a tech to view what is happening in the area normally obscured by the loaded tape), this might give a clue as to what is happening. On alot of machines, a problem with Rew/FFW would also mean a tape takeup problem in standard play, result in tape spilling out inside the machine. Sensors would catch this condition and go into a error mode, as yours is doing. One other thing which might be happening here, is the pinch roller not being disengaged from the capstan in the Rew/FFW modes. I think this is where I'd look first, and you can probably see if such is happening just by pulling the cover off the VCR. The pinch roller is just to the right of the rotating video head. In the play and forward/rev search modes it will press the tape up against the capstan (a rotating shaft). When in Rew/FFW, the pinch roller should be pulled back from the capstan, maybe 1/4 inch or so. Whatever the case, repair will likely take someone tech savvy. Costs might not be economically justified, with the low-cost, disposable rigs sold in the last 10+ years.

Tape is stuck in VCR- Fast rewind and forward


It may need to be cleaned. Mechanical problems are one of the big problems with VCRs they use alot of mechanical moving parts and play for so long they fail. Plastic parts dont help much either. The pinch roller takes up the slack and is usualy the part that fails first because it constantly runs along the tape and builds a coating on the rubber so it doesnt grip the tape and pull it back into the cassette. If its not pulling the tape back in then it hangs up inside and you cant get the tape out. Fastforward uses the reels to pull the tape not so much the roller. Try and stop 2 times then fast forward then eject the tape. Try and eject the tape while its fastforwarding so it doesnt do anything else. Sometimes machines will unload after its been in fastforwad a while then it will eject. You will hear a change in the sound when it unloads, you can hear the mechanical arms move the tape in and out of the cassette. Thats when you eject it. You cant really clean it till you get the tape out. YOu can clean the pinch roller with fingernail polish or paint remover. It is a wheel inside it looks like a black tire. It pinches the tape against the capstan arm this is why it developes a film or a shine on the rubber making it slip.

The unit will fast forward and rewind, but won't play


This is a problem with the process called 'tape loading' - pulling the tape loop out of the cassette and wrapping it around the spinning video drum, engaging the capstan and pinch roller and reel rotation. Check all the belts above and below the deck. Belts can appear to be firm but if they do not return immediately to their relaxed length when you stretch them 25%, they will need to be replaced. With the cover off, observe the behavior when you hit play. (You may need to put a piece of cardboard over the cassette to block external light from interfering with the start/end tape sensors). Assuming this is a basic VCR (no instant start features), you should see: 1. The video head drum begins to spin. 2. the roller guides move smoothly on the tracks, wind the tape around the drum, and stop snuggly pressed against the 'V-stopper' at the end of the tracks. 3. The pinch roller moves into position and presses the tape against the capstan. 4. The tape begins to move and is wound up by the takeup reel. 5. The picture and sound appear on the TV. With a 'rapid or quick start' (or it may be called something else) transport, the tape moves to a half-loaded position when the cassette is inserted. This is at an intermediate position partially pulled out of the cassette but not wrapped around the drum. On VCRs with a real-time counter and/or index search capabilities, the tape will be in contact with the control head. With an 'instant start' transport, the tape will fully load around the spinning drum when the cassette is inserted but the capstan will not engage and no tension will be applied to the tape until you press PLAY or REC. (After about 5 minutes, the drum will stop and it may unload to the half loaded or unloaded position.) Note that for VCRs with a real-time counter and/or index search capabilities, the tape must be in contact with the control head (but not the video heads) for all relevant modes. These VCRs (which include many modern units) must therefore pull the tape at least partly out of the cassette. In all cases, the completion of the sequence results in approximately the same mechanical configuration during PLAY. Several likely possibilities when it shuts down: 1. Everything occurs as above, picture and sound appear for a few seconds, but then the VCR unloads the tape, ejects the cassette, goes into REW mode, stops, or shuts off. Two common causes: The takeup reel does not turn and tape spills into the machine. This is sensed by the microcontroller which aborts record or play and attempts to save your valuable cassette. Most likely cause: old/dirty idler tire. As a test, turn the idler tire inside-out. The fresh surface will now work well enough to confirm this diagnosis and will continue working long enough for your replacement idler tire to arrive. See the section: "General guide to VCR cleaning and rubber parts replacement". The takeup reel is turning properly but
