I unplugged my Sanyo DVW 7000 DVD/VCR 4 head Hi-Fi system for about a half hour, while we were moving furniture. When I plugged it back in I couldn't get it to work. I can turn it on manually and get the numbers of a few channels to show up on the DVD panel, but I can't get any chanels to show up on the TV. I made sure that the remote to the TV was working properly. The remote to the DVD/VCR won't work at all. I made sure the remote was aimed at the sensor, that it was not too far away from the DVD/VCR, that there was no obstacle between it and the remote, that I had pressed the correct button to use the DVD/VCR through my TV, and I changed batteries three times. Because of the area we live in, the only way we can get a good picture on the TV is to run the channels through the VCR. Does anybody know what is causing this problem and how to fix it?
