I've recorded videos on the camera and when i want to play them back on my computer it simply says "video can't be displayed"

I don't know anything about the vhs camera - other than they produce superior quality, when they work ok.

It would be reasonable to assume the tape transport mechanism would be the same as in a vhs video recorder. I remember an engineer telling me there is a post or protrusion containing a light source and sensor that sometimes fails.

The purpose of this is to detect a cassette has been properly loaded into the machine and if it isn't working the machine won't work or only partly work.

I think the camera is worth saving but I strongly suggest such specialist equipment should be entrusted to a suitably experienced professional specialist.

take the lense cap off

Connect the camera with pc and try to check for error with any program like tune up or other online utilities... or if you have data card in it and you can open it in PC than simply copy your recorded videos so that you have a backup first. than you can freely show camera to any service center..

When you play the video back and get no sound are you doing this on your camera or on the computer? I have the same camera, and noticed that when I playback something I've recorded I don't have sound either, mind you I don't have static either. But once I've uploaded the video onto my pc the sound is there.

First, make sure you have it on CARD (and not DISK), and on the "playback" (and not record) mode. Next, does the camera play back other video clips normally, but just not a specific clip ?
Does the selected video clip frame (index) shown on the LCD screen have a picture ? If not, i.e. it is blank (dark), then it is likely that no video was recorded (i.e. just the audio) when you were shooting that video clip.
If there is a picture (of the video clip frame index on the LCD screen) and only audio is playing, try downloading the clip (from the SD card) to your computer, or simply try to play the video on the SD card (inserted directly into your SD card reader on your computer, or via a USB SD card reader) and see if the video clip will play normally on your computer.

The C182 records audio but does not play it back. To hear the audio, first transfer your videos to your computer and play them there.

Unfortunately there is nothing wrong with your camera. The ViviCam simply does not record any sound with its videos.

Once you've got the video preview on the screen, start the playback by pressing the shutter release button.

Sorry to say- but it is trashed.. It would cost more to fix it than it would be to buy a new one.
