JVC GR-SXM330U Camcorder with faulty viewfinder/lcd screen
I have a JVC GR-SXM330U S-VHS camcorder. Everything works except the viewfinder and LCD display. The image is scrambled in both Play and Record modes. When I route the signal through rca video output, the camera image and tape images are fine. All other features and functions are perfect. There is a hair and what looks like a bug in the viewfinder. Can this cleaned out by a home user? I have another camcorder that has a ton of specks and dust in the finder, to no ill effect. Anyone here take apart their camcorder's viewfinder system? I'll probably call JVC and get the details on repair costs, but I wanted to get some opinions first. I just found this NG and it looks pretty good. headscratcher. |

JVC GR-SXM330U Camcorder with faulty viewfinder/lcd screen
I'd worry about the missing synchronizing signals that are scrambling your
screens first. A competent camcorder tech. can find/fix that problem and clean out the debris as a bonus. The RCA outputs show the camera is not at fault so its something in the viewfinder video processing common to both screens that is messing up. You'll likely need a schematic and a scope to track that down. And maybe a good ESR meter as well. Good Luck Cosmic Ray Stellar Video wrote in message ... I have a JVC GR-SXM330U S-VHS camcorder.
