Panasonic NV M10 VHS Camcorder No Colour Buzzing Noise Repair

Описание к видео Panasonic NV M10 VHS Camcorder No Colour Buzzing Noise Repair

This camcorder had two faults, a constant loud buzzing noise on the audio and colour that was poor or non-existent. I find and fix these faults in the video. I will be coming back to this camcorder in the near future though as another fault appeared when I reviewed the test footage I shot.
