First let's find out if the motor is dead or
the magnetic clamp is to strong for the motor.
Press eject then listen closely for the sounds of struggling motor
if you hear it trying SLAP the top right over the DVD drive
and that should break the magnetic seal and release the tray
you may have to try a few times Press eject and open hand slap kinda
hard the top of the DVD drive , don't worry you won't hurt it.
if that works email me and ill tell you how to fix this.
ELECTRO MED SERVICES is partially correct with his answer but I'm pretty sure it's not going to be that complicated. First unplug the unit remove the cover and use 90% isopropal alcohol on a cotton swab or q-tip and clean off all of the metal pins that stick up and ride against the tape while it plays, then clean off the big rubber roller that pinches the tape to pull the tape at the correct speed. this is where most often the problem lies. the tape will get sticky and will bind up slightly. Then a there's a sensor on the left side that puts tension on the tape, if that sensor feels the tape is being pulled to hard and has no slack it will shut the player down and eject the tape. Another thing try another tape, that tape may have some hard rolling hubs or spindles. You can also try fast forwarding the tape to the end and then rewind it to make sure its not just rewound with something rubbing inside the tape case it's self. Sometimes the tape case will get deformed over years and it will rub on the tape spools inside and it will cause that sensor to trip when the tape starts to become hard to pull through the player. Also you can clean the big silver head but be careful no make sure you leave no residue on it. look at it with a magnifiying glass to make sure it's cleaned and free of any residue. 1 last thing that happens also is the automatic tape head cleaner will act up and cause problems, you can easily just remove that from the player and see if thats the culprit.
Start off with using a vcr tape cleaner make sure you read instructions some are just a brush while some others cleaners have a small liquid cleaner to add to it after using cleaner do not worry about rewinding it until another day you may need it.you can also try switching the progressive scan off if being used.If its eating tapes the tensioner could be loose or wore out or the locking mechanism is not working properly when tape is inserted.If you are not experienced in this field I recommend letting a shop look at it if so cleaning it is about the only thing you do also try opening the vcr tape bay door taking a deep breath and blow inside it without a tape in it do this several times it may just be dust and you can try unplugging it for 10 minutes to reset the device to see if its a stuck communication glitch in the board for the head motors.I hope one of these three basic tricks helps you.
is this question about the progressive scan when going to dvd mode more than likely the switch to control your p scan is on the back of your vcr/dvd player near the center look on the back and flick the switch to off usually the switches are just black moving left and right if not go into your menu and look for progressive scan mode if its not directly on the menu it is more than likely in the settings folder.Also if your remote is like the one i posted just click the p.scan button
They have inbuilt computers in them and as you know if the system crashes for some reason then like a computer it stops working. However this should only happen a few times and not all the time. If the device is doing it a lot you might be operating it in the wrong way or the wrong conditions - getting too hot for example - or have some kind of fault on it.
Some of them have a special reset button or a combination of buttons that will restore it without pulling the plug. It should mention this in the user manual. If you have lost the manual try searching the net for a PDF version. User manuals are generrally free, service manuals are generally not though.
