Re: Audio on recorded tape
You could try a wet type tape head cleaner but I doubt if that will help but it couldnt hurt. These combo units are built so tight together I wouldnt recomend that you try to open it. I would though look through the front door and look toward the right side and see if something got inserted into the machine and is blocking the audio head. If this dosent get you back audio then you have a curcuit problem and you are gonna need to take her in for an estimate Good Luck

to hear the audio fold back in prerecording mode you will need a tape that still has a security tab in it if not put some tape over the whole or even block the hole up
supply the tape unit with a good signal and then hold down the pause button and press the record and play button at the same time. you will then be able to monitor the sound you are about to record. use headphones as this to stops background noise in your ears and allows you to focus on the sound, "its another world inside your cans" adjust the input level until just peaking into the red. when you are ready to record leave the record button alone and the stop button and the play button just release the pause button and away you go. to stop press stop to stop recording say to cut out an advert or something just press pause.
I have a sony 14E and suddenly it stopped playing and recording. With vertical lines on the screen I knew to clean the heads. No effect on the recording/playing malfunction.
However I persevered and it seems to have worked in it is now recording and playing back. The steps I suggest, with PERSEVERANCE, are :
1. Clean the heads (I did it 3 times in all, with about 1 hour between each session);
2. Leave the camera open (tape section) for about 2 hours and put the camera (with or without tape) in a warm place. (I also had condensation messages).
3. Once it is warm put in a recorded tape and attempt to view it. At first I had "dirty" vertical lines for a few seconds but it cleared and played normally.
4. If Step 3 still does not work repeat 1 and 2. As I said PERSEVERE.
If Step 3 works then try to record. It should work hopefully. If not, repeat 1 and 2 (shortening the "Warm Up" time).
Good luck. I hope mine continues to work OK now. It is to do with dirty heads and coldness I think.
I was having the exact same problems, and I read a post on this website somewhere recommending that I just record a few seconds of video on a blank portion of tape and then the camera should start playing video normally again.
If it plays back pre recorded tapes then there is nothing wrong with that section of the unit. Does it playback audio and not picture or does it not playback anything.
Also, when trying to playback a recording what is seen of the screen? Snow(black and white dots or wiggly picture?
The unit uses two separate circuits to record and playback tapes. Is any thing else connected to the unit while you are recording? If you are using anything plugged into other ports on the recorder it may not see the camera input causing it to not record anything..
recording in a video tape requires 3 tracks. one is for video, the other is for the sound and the last one is for the control trrack. it means that sound recording is being done separately. there is an audio head inside the vcr that looks like an ordinary audiotape head, clean it with a cotton swab with a little alcohol on it. let it dry and try. if the problem persist, a problem in audio circuit during recording is the culprit, considering playing is normal. but if in both ways is the same, maybe the head itself is the problem
Audio Dubbing on DV:
Here's how you do this: Play your tape on the TRV-9 and feed the signal into the TRV-900, using the Firewire connector. Set the TRV-900's audio option to record in the 12-bit mode. When this is done, you will have the video re-recorded on the TRV-900 and the audio laid down on the primary 12-bit audio channel. Then, you can run the tape back through for a 2nd pass in the TRV-900, with the recorder set to the audio-dubbing mode. The audio you put into the TRV-900 this time, will be recorded on the secondary 12-bit channel. You can select either 12-bit channel when you play the edited tape back or you can mix both stereo channels into the output.
Once you record on the 16-bit channel, you can't dub audio back onto that recording, without erasing the original channel, as the recording space for both 12-bit channels is occupied. You can't selectively re-record just audio onto the 16-bit channel either, without the video being re-recorded along with it. Both video and audio are sent over the same Firewire connector, so you can't input them from mixed sources, as you can with analog recordings.
Only the secondary 12-bit audio channel can be used in the audio-dubbing mode. You can't dub onto the 16-bit channel or onto the primary 12-bit channel. The primary 12-bit channel can be used only when you're recording video along with it.
