SONY SLV-750HF need servo schem
I need the capstan and lower head cylinder schematic for this Sony. I
believe that one of these circuits is causing my problem. When you press "play", you get audio and video for a second. Then, blue screen. Does it on SP as well, but audio sounds slow on that speed. I can also get it to play just for a second if I slow the pinch roller or remove the tension off of it with my fingers. Have tried aligning the control head (audio is crisp)however, I cannot find a 30hz anywhere in the servo circuit. (Control head is not open). I have replaced the capstan motor with no results. It's doubtful that a head is bad because the video is perfect when it's there. I hope that someone has a diagram for this unit. Thanks in advance, Rick |
