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

Is the back tension band in good shape?
Do you have a Tentelometer to set the proper back tension?
