There is something wrong with the mechanism, either the main drive mechanism, or the cassette holder part. Possible physical damage to the plastic parts. When the tape is inserted a device called a mode switch tells the electronics which position both mechanisms are in. If they go out of sequence, due to damage, or a faulty mode switch, the electronics shut the system down to prevent tape damage. When you power it up, the system thinks it is eject mode and chucks out the tape.
VCR's with faulty mechanisms will power down to prevent tape damage. Checking inside might reveal damage to the tape mechanism. Even if the mechanism isn't damaged the VCR has a device called the mode switch. These tell the electronics what position the mechanism is in. If that goes faulty the electronics can think that mechanism is in say playback mode, even when it's in eject mode. So when it detects no tape tries to stop and eject the tape. Since it can't carry out this it shuts the entire video down to be on the safe side and prevent further damage.
A couple of reasons. First the carriage the tape sits in is damaged. Next the mechanism that moves the tape is damaged and can't except a tape. Lastly or perhaps due to the later, the mode switch is faulty or not in the right position. The mode switch tells the electronics which position the mechanism is in, be it play, fast forward or eject etc. If the switch is faulty and stuck in eject then it wont except a tape.
Hi Anonymous, always check fuses and bulbs first, you could have a faulty turn signal module or a bad turn signal button/switch, remove it from the switch housing and check for continuity, check your wiring and connections from the turn signal switch to the turn signal module with a testlite. Make sure all wires are not worn or pinched and connector pins are not corroded, broken, or loose.

Probably somekind of damage has occurred inside to the mechanical section. Only looking around will show the cause. When VCRS have a problem playing or any function doesn't do what it is supposed to do a device called a mode switch will go of position and give faulty readings to the electronics, so they power off the video to prevent further damage. The mode switch itself can ware out or become dirty and give false readings on a good mechanism, so that should be checked too. Sometimes you can get away with a spray of Servisol Video 40 on the switch, but if there's any damage cleaning it wont work.
Image below of some mode switches, but they do vary from model to model.
1st is the proper method - After unscrewing the screws near the usb head, take off the cover. Near the jack input area is another small screw, take it out. You can now take out the main board by pulling away from the jack and up. Take a look at the but end, where all the copper foil is. Do NOT remove the copper foil or the tape around, it is your ground (protects your chip if sparked). If you see a blue t shape thing that is your switch. If you don't, check answer 2. This blue T switch has to have the base of the T in-between the 2 forks on your hold switch. After fiddling for a while you will get it and then just screw everything back together.
2nd method - You will need some metallic wire and tape. IF you do use this method you can NOT use the hold function, unless your are skilled at fiddling with wire. You will have tak some of the wire and make an oval ring shaped hole with it. Press the wire ring through the hole below the copper foil. you want to press the ring upwards. Press the power button and make sure it is in the proper position. If not then fiddle around until you get it.Once you have achieved the position tape the ring down in it's position. Turn on the mp3, if it works good, you now get to re-assemble. If not then, go back and fiddle with the wire and tape again. (You might achieve the same goal if the wire is straight BUT the wire moves easier). Once it is all back together turn it on one last time and if it works embrace the hard work you just did. If not, sorry to say, go back to step 2 and start over again.
***Both Methods Work*** *I did both and my own unit still works*
you need to clean the vcr with a cleaner that you can buy at a store. If that doesnt work then you need to take the 4 or 5 skrews out that hold the top on and look at the motor and gears move while you put a tape in and you should spot the problem pretty quick. It'll be with the round metal wheel that turns the tape.
Do you know why the tape was stuck? How did you get it out? On most vcr's there's a mode switch connected to the mechanics of the vcr. If the mode switch isn't in stop position, the unit will try to get it there and shut off if it can't. Bad belts, bad idler wheel, dirty mode switch, mechanical timing off (maybe due to forcing a stuck tape out?)... all these can cause this.
