<div>Is it possible the other two tapes were made on an Ampex and the Sony is being forced to V-sync on the sync track? Been a long time since I dealth with a 3100, but It's something to check. A re the recordings on the tape the same format as the reference to the machine? PAL, NTSC, etc. Are you sure they are C-format tapes? Lots of non C-format machines in the world. Check that V-ref to the machine is o.k. as well. Sounds like you are not finding vertical coincidence for some reason. </div>

>>As a newbie to 1" inch I have observed a few things that I would like to have your input: <br>
1. My machine was broken (a Sony bvh-3100ps). After hours on the bench and many caps replaced we got to the point where it would turn on, test itself and say it had trouble. I managed to find a person kind enough to offer me extra boards to test and find out what is wrong. It turned out to be board #2 (SY-103). The machine now plays tapes. <br>
2. I have 3 different tapes on hand. A Sony v1-k, an Ampex 196, and a Scotch 479. The Sony played from beginning to end without a problem. The other two didn't lock. The cap and mode lights keep blinking and the display show sv-90 ref and TBC ref flashing. <br>
3. There are so many parameters there that I have no idea what to do with. I have no manual printed but have PDF. I will try to print the first part to see about setup, but any suggestions are welcome. <br>
4. What is the difference in the capstan lock mode between 2,4 and 8? <br>
<br>
Humbly yours <br>
