And add-on mic is cheaper than what most charge to just look at the camcorder. I'd take the chance.

So I have had my Sony TRV-27 for a few years and rarely use it. A few weeks ago was my daughters christening and I had a buddy film it with my camera and tripod. All the audio is shot. Just loud static. I recorded at home, same thing. I hooked up the camera to my home receiver and in stanby mode all you hear is static being fed to the receiver. I checked all setting, 12bit, 16bit, no difference. Source 1 and 2, 1-2. Nothing. I have not tried an external mic as of yet. I was considering just buying an aftermarket mic, but not sure that would fix the problem. Since add-on mic's arent exactly cheap, I might just have to get a new camera.
Anyone see or hear of anything like this before?
