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!

  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!
