Question about Video Cameras
I have the same issue and found that on most forums that the only way to fix it is to try smacking the side of the camera relatively hard with the palm of your hand. BUT, I discover the issue, the issue here that the cam did not recognize when the tape starts at the begining, So the cam try to keep rewind the tape to reach the begining while in the real the tape is in the begining and this cause such error, How I avoid that, Just you need to forward the tape (MANUALLY) from its begining couples of turns (rounds) and then turn the cam, suprize it is working....lol.
my conclusion is if you use the tape couple of times then you need to replace it...Mohanad.

Go to youtube tutorial on this at http://www.youtube.com/watch?v=VUIN-ygjN_g. Look at it carefully before smacking your camera. I did it and my trv25 works perfectly

Sony says the unit needs a power reset (error 31). Unplug the camera, remove the battery and wait several minutes before re-attaching the battery and/or AC cable. Then power the camera back up. The 23 code says you need to use a InfoLithium battery-- apparently these are smart batteries that give data back to the camera. These error codes seem to be quite common however, and so a hardware issue may be the case. Some users have said that removing the battery while the camera is powered on will clear the codes. Others advocate "smacking" the camera, I would not however, recommend this. www.sony.com is a good place to look for more information.

the reel sensor is the problem of your camera...in my job as a technician i always encounter that..it is a poor connection of the sensor to the mainboard..try to clean the contact using only a pencil eraser..

Sony is a ******* piece of **** corporation that has foisted their name on professionals and consumers as being the epitome of high technology for all forms of media. They are, in fact, scam artists that have perfected the art of programmed obsolescence and early life failures for their equipment. Because I have been a professional video/audio engineer for 30 years, I have been forced to own and use more Sony gear than I am comfortable admitting to. There is NO answer to your dilemma because it is a defect programmed into the circuitry of Sony DV-Cams that will ultimately force you to take the machine in for repairs...again and again and again and again....
Do your self a huge favor and smash that piece of **** with a sledge hammer right now. Then, go out and buy a Canon. Great products and great tech support. Sorry I couldn't solve your problem for you. But, I am an engineer and I can't even solve this one myself.

the error c:31:23 error pertains to one of the reel (part that turns the tape) is malfunctioning. although you can play back videos, you would definitely have issue w/ recording, rewinding or fast forwarding the tape.what you can do is to turn the camcorder off.remove the battery and ac adapter for at least a minute.insert the battery or reconnect the adapter.you can also try pressing the reset button (located near the top of the speaker, on the panel where lcd screen goes to).make sure cam is on when you do that.if still your getting this problem, service would be needed for your cam.hope this helps :)

Tips for a great answer:
This is usually caused by a defective component in the tape detection circuitry and can usually be repaired fairly inexpensively. However, it's not a user serviceable problem and will need to be repaired qualified service technician.
My name is Rick and I'm a professional repair technician with over 20 years in the business and have repaired many of these. I'm semi retired and work from home with little overhead so I can keep repair costs low. If you decide to have the camera repaired, please click HERE for a directory listing that suits your needs.
