I found what you are looking for. I just finished fixing my Sony DRV-TRV120. The sony Error code says moisture I dried mine for months, Pulled all batteried and it still didnt work. I seriously left my camera in its bag Several Silica Gel bags in it (Remeber to NOT eat) for at least 2-3 months and it still did not work. I was looking to buy a new camera and thought I would look one more time for help. I found it!!! The solution to fix this problem was very hard and takes along time to fix LOL....just kidding The site says to turn off and remove all batteries and HIT the camera. I removed all batteries and hit the camera once with an open palm on the bottom of the camera. Gave it power and turned it on and NO MORE ERROR... I am not suggesting that you abuse your camera, try to dry it out and/or seek out Sony support and/or Warranty. This link has more people talking about this and other errors. Check it out. http://www.globalmediapro.com/av/messages/135625-3.html I have a Birthday party tomorrow so I am going to try this camera out fully tomorrow. I will give you more details after :)

Sadly It worked on my pc1000.. I wonder what SONY would say about this...Thank you a lot..

Got C:21 code today and did what the you said and hit the bottom of the camera with my open hand and it worked!! Many thanks for the info;)

ME TOO. IT just worked for me.That is one crazy fix. Brings new meaning to "reBOOT" it. Thank you all.

Sistema rudimentale ma efficace...!!! rudimentary methodology but effective

It worked!!!! Also on a DCR-TR8000E.Unbelievable. Many thanks!!!

OMG!!!! I was very wary of doing this, My cam is the TR8000E and it hasn;t been working for ages, I tried your method and it's working!! Un-believable!! Thanks sooo much! I have film on their of my late mum, so it's very precious, Thankyou!!

I had the same problem with my camera, missed several interesting concerts I was planning to videotape, today I found this site, took the advice, a few slaps and the problem got fixed. THANK YOU THANK YOU THANK YOU! I'm indepted to Trevor and the guys who figured it out.
