Hi When I insert a tape into my vcr (sony model no.SLV430) ,the cartridge goes in, the tape loads around the drum and after about 3 seconds, the tape retracts back into the cartridge and the cartridge ejects.This is all it will do. Anyone have any solutions for me? Thank You, Ray
Have you tried different tapes?
Ray,
Sounds like this might be caused by a defective mode switch. Depending on the model, you may be able to open the switch and clean it and not have to replace. Good luck and post what you find.

How can you be certain the tape is fully threading around the drum and the tape guides are locking into place? Did you remove the VCR cover and observe this? If the threading sequence has completed, cassette ejection most often results from the tape take-up spool failing to turn at the appropriate rate, alerting the VCR to a "critical" malfunction -- the VCR believes something has gone horribly wrong which could ultimately damage the video heads and/or the tape, so the tape is spit out. Are the tapes being chewed? Is tape edge curling (creasing side of tape) occurring?
Assuming the tape threading sequence has properly completed, a number of things come to mind (not in order of probability):
Bad belt(s) Excessive back tension (tape will be forced tight against drum; you'd hear squealing noises and the drum slowing down) Worm gear slipping on shaft (cracked); not turning cam gear Stripped cam gear not engaging mode switch or not moving drive wheel into position Worn or dirty mode switch (as someone suggested) Bad tape-end sensor Bad dew sensor (or moisture actually present) Excessive resistance of tape spools (try a newish tape and see if it does it; cheap tapes are common culprits)
These commonly have problems with the carriage timing. One of the lower gears is off by a tooth or 2. This is due to sloppy tolerances, and tends to recur after fixed. There is a "fix" which involves adding a washer on the right side, which is to brace the right side of the carriage as the tape is inserted. This isn't all too reliable either, though.
