This can be repaired fairly inexpensively. However, it's not a user serviceable problem and will need to be repaired by a qualified service technician.

The most likely cause for this is a damaged or defective flexible ribbon cable that connects the LCD to the camera body and can be repaired fairly inexpensively. However, it's not a user serviceable problem and will need to be repaired by a qualified service technician.

You can purchase a new LCD Flex cable for a Sony HDR-HC3 (Same as HDR HC7) from e-bay for 27 US$.

You can use a powerful magnet swipe it up against the side of the tape several times or you can just tape over them again or you can put the lens cap on the camera and press record

Bill,

The problem is with the S-reel. Take the tape out, remove the battery, and give it a slight bump. This usually fixes the issue for a couple of weeks. I haven't heard of any permenant fixes. I took my cam into circuit city (before they closed) twice for the same issue. Very frustrating when you don't know what the issue is.

I have the same problem. If I remove the battery for a few seconds, then replace the battery and wait about 5 seconds, the tape compartment closes.
