Did you change the inputs on your tv to match where you are hooked into?

the tape coming back out and unravels the tape means the loading mechanism is the problem----when a tape goes in it loads the tape down, then it pulls the tape out of the cassette and puts it up against the drum with the video heads-----many of these are belt driven and a bad belt or belts will cause this----it is called the loading and or transport mechanism.......when it fails the arms come back but the tape does not get rewound back into the cassette so it mangles it when the cassette door on the tape closes----most likely a belt or the drive idler which also rewinds and fast forwards the tape.

Usually when that happened for me, it meant that one of my small children had also put a foreign object in the slot where the VHS tape goes. Any type of obstruction will cause the VCR to jam and force the television to shut off.

The answer is YES YOU CAN! Take advantage of one-touch recording from videotapes to DVD+/-R and RW discs or from DVDs to VHS tapes. A variety of different inputs also let you record from compatible camcorders, external TV tuners or cable boxes.

CONSUMER ALERT: This model does not have a built-in tuner for recording TV programs and will not record copy-protected tapes or discs.

I've found the center LED in the VHS player faulty with those symptoms. Change it you'll be fine. Larry

You will need to get new cables.

unfortunately the tape clamp sensor is broken or worn, or could have dust or dirt obstructing it and they don't have parts for these anymore, the tape clamp sensor is like a tiny white plastic sensor only a few millimeters in size with a red eye inside the edge of the tape carriage, and needs possible cleaning, it could be something as simple as dirt inside the mechanism over the sensors, the Tv will power down when the error occurs not much you can do if a clean or high output air blow of the components don't do the trick. sometimes dirt in the circuit can cause it to do that too, ....im surprised it lasted this long actually they were great for the bedroom, i had one ages ago they are available on ebay for about $100 or under now ...Sorry i couldn't be of more help.......you may get away with disconnecting the white feed ribbon cable that powers the tape cartridge and just use it as a DVD and Tv, that should stop the error.

The same thing happened to me and it is the power supply. You can get a new one at [email protected]

is the VCR trying to eject a tape even if there is no tape in machine. then shutting down ? if so the vcr sensors need to
