It's no myth! As to parts, this article covers it well.
Yes I know, not about your camcorder but the note about PARTS does apply. If you can't get parts from Sony, ebay or craigslist then you know what's next.
I have a Sony HDR-SR11 Camcorder that will not record when I select the record button. It got wet when I was filming Niagara falls and the water was too much.
I was able to download the video from the camcorder that was recorded prior to this problem. When I turn on the camcorder all other functions seem to work except the record and playback. I formatted the hard drive and still no record. Also, after I try to record using the record button, the off switch will not turn off the camera, the hard drive seems to spin. When I turn it back to the on position it stops spinning. I have to remove the battery to shut it off. If I turn the camera on and then turn it off, it turns off fine.
I have the service manual with all the parts listed and cannot determine if one of the cards or wire strips went bad. I could buy the replacement part and repair myself.
Does anyone have any experience with troubleshooting this?
