JVC video recorder - replacing rubber band

Not spinning disc If it spins with a little help from yourself replace the spindle motor with improved motor, part number: RXQ0749A Unable to detect discs The laser head was the culprit. Replacing it fixed the problem. (Laser head code GRP6278A) Dew indicator is on permanently. Cannot play or record tapes. No dew present - caused by internal fault This Camcorder uses very fragile flexible circuits to interconnect the PCB's. They plug in to edge connectors. It seems that when they made these camcorders at the factory, they had as many problems getting these film flexy circuits back into the connectors as us service engineers have. I saw one unit that had a crease in the flexy circuit which had caused a hair-line fracture. Solution, trace the wiring and solder a sub-miniature wire across the broken track. Don't disturb any flexy connectors that you don't need to. This camcorder is a **** to work on Not loading properly Usually due to incorrect head alignment or dirty head, or failure of LM324 op-amp Doesn't record properly, ie: looks like one channel is down when recorded, pre-recorded tapes are ok Check Q008 for dry joints
