Adjust JVC VCR with Jig RCU PTU94023B remote?
Hello,
is it possible to adjust the video circuit of the JVC SVHS Recorder HR-S8960 without the JVC Jig RCU PTU94023B? Is there a source where you can buy it or another way without using the JIG Remote or a replacement for the original JIG remote? From the service manual: Signal (A1) • Ext. S-input (A2) • Ext. input (A3) • Color (colour) bar signal [PAL] Mode (B1) • EE SP (B2) • S-VHS SP (B3) • VHS SP Equipment (C) • Oscilloscope Measuring point (D) • Y OUT terminal (75Ø terminated) EVR mode (F1) • Jig code “57” EVR address (F2) • A : 11 (F3) • Jig code “21” twice (F4) • Jig code “18” or “19” (Channel +/-) Specified value (G) • 1.00 ± 0.05 Vp-p Adjustment tool (H) • Jig RCU [PTU94023B] (1) Input the signal (A3) from the input point (A1). (2) Set the VCR to the mode (B1). (3) Observe the Y OUT waveform at the measuring point (D). (4) Set the VCR to the EVR mode by transmitting the code (F1) from the Jig RCU. (5) Set the EVR address to (F2) by transmitting the code (F3) from the Jig RCU. (6) Transmit the code (F4) from the Jig RCU to adjust so that the Y level of the Y OUT waveform becomes the speci- fied value (G). (7) Release the EVR mode of the VCR by transmitting the code (F1) from the Jig RCU again. (When the EVR mode is released, the adjusted data is memorized.) (8) Input the signal (A3) from the input point (A2). (9) Repeat steps (3) to (7) in the mode (B1). (10)Record the signal (A3) in the mode (B2), and play back the recorded signal. (11) Set the VCR to the manual tracking mode. (12)Repeat steps (3) to (7) in the mode (B2). (13)Record the signal (A3) in the mode (B3), and play back the recorded signal. (14)Set the VCR to the manual tracking mode. (15)Repeat steps (3) to (7) in the mode (B3). |
There was a recent discussion about the JIG. Somebody was going to send me some sort of device that could replicate the commands, but then I never heard back on it. I'm too busy to chase that down, but I'd do it if given clear how-to info. I have a JIG, but not selling it, not lending it. If we can replicate the buttons, I'd like to do that.

In looking around for a JIG, I came across this post about replicating it- https://www.avsforum.com/threads/jvc...4023b.1531093/
I don't know enough to understand how to do it though. |
