Commercial Advance feature shuts off vcr.

Check the condition of the rubber pinch roller that holds the tape against the capstan post. As the rubber begins to dry out and have less resiliency, it is less able to pull the tape in either direction during the slow speed search movements. (Hint: this also makes the tape rewind almost slow to a crawl as the tape is nearly rewound to the beginning.) If the VCR tape movement sensors see it go slack or too slow, it will trigger an automatic shutdown to protect the tape and the machine. I have been able to clean and apply a "Re-Grip" solution to the roller as a temporary repair. After a while, it will slip again. Replacement of the roller is the best fix.

You need to clean the video tape path my freind, or the machine needs an alighnment. you can try to clean it with a head cleaner, and it might work, but most of the time you need to have it professionall cleaned. If you want open this http://www.bealecorner.com/trv900/trouble/cleaning.html, and it is about the same proceedture with a camcorder to clean a VCR, just take off the top cover of the VCR.
