Re: FIX!!! for Self Diagnosis C:31:22

Had the same error message on my TRV-720, and could not come up with a solution for weeks until I found this website:

http://www.protechcam.com/wwwboard/messages/127.html

Now the fix you will not believe, nor did I at first, but requires you to power off the unit completely and "Smack it" a few times fairly hard.
Now you may do this at your risk, but I swear it fixed mine and all the other people listed at the above web site.
I thought it was a joke - but it works!!

Good Luck!

  Hi.
  To smack the camera is an interesting solution. But some camera can be damaged, if you smack them too hard. I had the same problem whit my Sony CCD-TR840E. I try the “smack method” but its only work for few minutes. I find another solution, since a smack help a little I suggest It must be something loose in the camera. I take out the cassette, powered off the camera, and touch very carefully a little white cylindered wheel away from the black wheel. I also open up “Bend out” the slides for the cassettes, so the cassettes smock smoothly into the camera. All irritating sound disappears and the camera is working very silent without any fault.
  
  Good luck!

  For all you smart guys out there, I had this error for 2 years. About to throw the camera out the door. Decided to give smacking it a shot. When I did, a small cyndrical guide wheel was jarred loose. After taking a few minutes and using common sense, I figured out where it belonged. Re-inserted the guide and fired up the camera. Works for the first time in 2 years. For others out there, check for any rubber guides that may have come loose. This is probably the problem.

  Hey everybody,
  I am a football coach and we rely on film for everything. When I was working with a Sony D8 in '04 this happened, but I had no solutions and passed the problem on to somebody else.
  It's 2008 and this message pops up an two different cameras. I read the forum, tried it, and now both work like a charm, so far. I'll let you know if they don't over time.
  
  Give it SMACK!!!!!!! It worked for me on two different Sony D8's!
