Service manuals usually contains circuit diagrams, printed circuit boards, repair tips, wiring diagrams, block diagrams and parts list.I'm new here and I found this forum by searching for information about the BVH-2000/2180 1" C-Type Video Tape Recorder. Description of SONY BVH-3100PS VOLUME 2 Service Manual Complete service manual in digital format (PDF File). Up to ten cue points can be registered with the BVH-3000/3100.And I don't have an alignment tape. Before I go further though, I have to admit two things: I made the major mistake to forget the extender card at the location where I got the machine from (stupid me.) and the machine is still at my old place (I moved recently and didn't get the chance to move this heavy monster as well until now). I have a Sony BVH-2180-PS machine which is working okay so far - more or less at least.

So I thought I might give it a shot here?!Unsorted Sanyo Service Manuals.No matter whether I play a pre-recorded tape (such as a Submaster Tape I got from TV stations) or I play a tape I recorded myself.

Sony Bvh-3100 Service Manual Complete ServiceI then tried to hook up my oscilloscope directly to the AP-Board which contains the reproduce amplifier for the CTL track head. The machine allows me to see the CTL track signal directly on the oscilloscope output but there I didn't see any signal at all. As far as I can understand, this track is used to synchronize the drum servo to the tracks on the tape (?). I have perfect audio, so a major misalignment of those heads doesn't seem to be a very likely problem (?).I cleaned everything thoroughly and tried to check whether the CTL track is even being read using a pre-recorded tape which, by my understanding, should have such a CTL track recorded. When using the DT head without the TBC, the image is clear but very unstable on my reference monitor.I noticed that the CTL track is read using the same head as used for the audio tracks. As soon as I switch to the regular R/P head, the image is heavily distorted, it periodically fades from a more or less acceptable picture to a black screen and in beween it is distorted, has black lines all over it and of course the TBC is unable to make anything useful with this chaos. While the machine is playing, lift up the control panel and take a look at the RL-12 board (it's the reel servo controller) you will see a row of eight LEDs, four on the top and four on the bottom. This would certainly make my day!I assume that the servo light you refer to is the one on the control panel, right? That LED is driven by a lot of different systems, so the first step is to narrow down which servo is producing the alarm. This would be so great!Concerning me not having the machine at my new place: If there is someone around here willing to help me, I will organise a transport so that I can carry out whatever there is to be done or checked right here at my new place.I really hope that someone reads this post and thinks "yes, I will help this fellow!". This machine is really something else and I want to see this red LED extinguish when playing back tapes. Although I have a Master's Degree in Electrical Engineering and specialized in signal processing, information and communication technologies, I am in need of some help here. Serial ebp devis et facturation 2010 1040As a result, the control track pulses winds up in a definite position that relates to the position of the video tracks.During normal playback with the R/P head, the capstan servo works to make the control track pulses synchronize with the incoming playback reference the drum servo then positions the drum according to where the control track pulses on the tape wind up. During recording, the drum servo positions the head so that it begins a new track toward the end of a vertical interval period the control track pulses are also generated to correspond to a particular point in the incoming video. On the SR-15, try setting the SC ADJ toggle switch up to the MANU position, and turn the knob above it to make the SC PHASE meter's needle move to the center mark.Here's the nickel tour about the control track: it's a series of pulses recorded by the same headstack as the audio channels, and its function is analogous to the sprocket holes in film: the pulses delineate where the video tracks are on the tape, in the same way that a sprocket hole has a definite mechanical relationship to the position of a frame on the film. You can make the machine lock more easily by setting the CAP LOCK switch to 2F. On the CD-17 board, set the top toggle switch (ADV) according to the type of time base corrector you have: if it's an external BVT-2000, it should be set up to BVT if it's the four-card internal TBC, it should be set down to BKH. On the RL-12 board, also make sure the SKEW switch is set to AUTO. Heads that have been refurbished sometimes come back with really weird tip projection. A new R/P or DT head typically measures around 90 microns you start having this sort of problem when it gets down around 50. This automatically compensates for tape variations better still, it has enough correction range to make up for a ☒x tape speed variation (that is, ranging from –1 to +3 speed).The fact that you are seeing video on the DT head suggests that your signal system is working properly, and that the servo is pretty close to normal.Do you have an eccentricity gauge to measure the head tip projection? Absence of playback RF is often a result of the tip having worn down. The DT head is mounted to a quartz piezo element that is driven by the DT-04 board the short version is that the DT-04 board adds a small sinusoidal wobble signal to the piezo element, and watches the recovered RF level from the head it adds a DC control voltage to the wobble so that the RF is at its peak when the wobble signal is closest to zero. If you look at the front of the MD-14 board (toward the left), flip the METER switch to the up RF(V) position the meter above the tracking knob will show you the RF level coming from the video head, so you just rotate the tracking knob to maximize the meter reading.Playback with the DT head is very similar, except that the tracking knob is taken out of the loop, and the drum servo moves the drum 120° around so that the DT head is lined up with the track on the tape instead of the fixed R/P head. Inevitably, there will be variations from tape to tape, so the tracking knob (you have to pull it out for it to have an effect) slightly advances or delays the drum servo so that you can position the head in the center of the recorded track, and maximize the playback level. Ipad emulator macA pretty good freelancing gig for a fellow starting a family. In my younger days, I had my hands on most of the BVH machines in the Central New York area at one point or another. But it brings back several weeks spent in the Sony training facility in San Jose, back in 1985. It's not such a problem during recording: whereas playback response is strongly limited by the gap width (the induced voltage is a function of the differential flux density across the gap), the signal imparted to the tape during recording is a function of the flux density at the trailing edge of the head as it moves across the tape.Okay, that was long winded. ![]() The servo problem remained though.What does this SC ADJ do? There are so many abbreviations that I sometimes struggle to keep track of what they all mean. But I remember that when I did, the stop button stopped flashing. I really want to solve this issueI mostly don't supply a video reference signal and just leave the machine run on its own.
