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. 00:00 Intro and fault overview 03:21 Supply circuits 07:23 Disassembly 10:24 Power supply waveforms 13:50 Hi-Fi regulator circuit 14:37 Hi-Fi regulator waveforms 16:06 Replacing parts 22:33 Testing 23:50 Chroma circuit 24:41 Chroma suppy waveforms 25:50 Replacing parts 28:32 Luma supply checks 30:06 Replacing parts 31:19 Testing 32:27 Reassembly 36:31 Test footage
