problem with loading a vcr tape into the player. It wont accept tape, and gives strange codes- '71501' & '21509', I can't find what they mean anywhere?? You have to force the tape into the player, and if it does take the tape, it immediately pops it back out with excess tape loops outside of the tape case. Is there a motor, or something electronic that could be bad and causing the problem? Is it worth trying to fix?
