Help w/Emerson VCR Tape Transport

Yeah, I know...POS. Emerson VCR755. Don't want to knock myself out here; the tuner has dropped 50% of the channels but the VCR worked fine. Now, tape loads,FF,RW,Eject all ok; Play: tape transport arms move 90%, retract, and the VCR shuts off. The belt is OK. I can't see the geared idler with the tape in. Pinch roller/capstan contact, but capstan doesn't run. Don't know if it's supposed to before tape transport completes. The motor runs back and forth during play initiation, and the tape does not de-spool, but ends up tensioned normally. Seems to be a logic error; should I shoot for two at the nearest dumpster? JR

Some of those emersons had a plastic arm by the capstand shaft that would crack and the pin would slide down or all the way out. Doug

JR NORTH: Folow the suggestion from Nolsar regarding the MODE switch. You do NOT need to remove the ribbon connectors or the deck to work on it. The mode switch can easily be serviced without removing the deck from the cabinet case. Almost all other service can be done this way too. electricitym

JR North: Without removing the deck from the cabinet you can easily service the mode switch...... unscrew the bottom board, unsolder the 5 contacts to the mode switch, gently lift up the edge of the board and completely remove the mode switch.... it can then be snapped apart, contacts cleaned and increase the spring tension on the contacts by gently and slightly bending each one. Reinstall and resolder the connections. The good news is that the Emerson mode switch has a small protrusion that fits in a hole on the cam gear so it can not be mis-timed. Again.... you DO NOT have to remove the deck to do this service or just about any other service on the 755..
