Unbelievable. I have had this JVC GR DVF 21 not working for at least the last 5 years. I read this quick fix and tried it. To my amazement, it worked. My recorded is now working again. Unbelievable. UNBELIEVABLE. Am I spelling that right? Thanks a million times.

someone is a genius -solved error code 4 problem on JVC mini DV by tapping underside as suggested-many thanks- instant cure!!

Juan, You ROCK!!! Just goes to show you. Some things just need a good whack!!!

I have a gr-dvm90, I was about to throw it out the window then I read your post, IT WORKS!!! Thank you so much. No I can film my friend and I doing stupid stunts and getting killed snowboarding!

I can't believe it! It worked! How funny :)

Hi Juan I have the same problem & would be grateful if you could let me know what you have tried & if it has worked cheers Steve

I don't believe it but Juan's suggestion worked for me too.
