Sylvania combo tv/vcr turns self off

Possibly have a tape drive motor issue it powers down to save itself .Thats the dickens with those combo sets they are hard to look at ,you have to take it half apart just to see whats going on

NEED REPLACED VCR LODING BELT OR REPLAIRED MECH ASSY

check the motor charge belt on the vcr and change it

could be that either the dvd or the vcr are malfunctioning, usually it is the vcr that creates the problem. If you turn tv on and set vol to low see if you can hear the noise of the motor loading or trying to load,with out a tape inside. It may be a good idea to have a qualified tech repair it, these units are difficult to work on and further problems may come up if you are not familiar with the tv.

The VCR is not turning the TV power off. The tape is not playing. I'd guess maybe it needs a cleaning or a replacment.

You need a new VCR belt it located on right side of the vcr tray take your finger and start rotate the belt clockwise, it should release the tape. or the motor is going bad.

my same make tv shuts off afetr so long by itself

the rubber band inside for the ejecting mechanism broke. you need to take it apart and reattch with a rubber band.

the tape carriage is probably stuck, or something stuck inside blocking the tape sensor.
feed a tape in and see if it does it "with" the tape too

hope this helps

With the set unplugged remove the back and extract the main board. You'll find a metal cover over the tape housing area that is easily removed by removing some screws holding it to the board area and manipulating some wired over it... You should then be able to see the tape and what's hanging it up. If you need to unwrap tape from the pinch roller or around the guides do so carefully. When it all looks free you can either manually crank the load motor assembly to eject the tape or put it back together enough to plug it in and press eject. If you do the later be VERY careful... Good Luck! Bill
