From the description, I guess that this could be one of many problems, but since it's a Panasonic 4-head, it *could* be related to the problems that I've been having with my (rather more recent, but probably closely-related) Panasonic NV-FS90B. I bought it 6 months ago, and after 3 months it started to give noisy playback, similar to your description, but only on SP. When I put it into SP "slow motion replay", alternate frames are good, and bad (heavy noise, much worse than that seen in normal play). This looked to me like a single head failure, and the shop's repairer (on the 2nd attempt), replaced (under guarantee) the drum assembly. 4 weeks later (a few days ago) it failed again. I feel rather pessimistic about another head assembly (this seems unlikely to work and, even if it does, how long after the guarantee period is it likely to last?). I would be really tempted to take this thing apart and take a look myself, but, of course, that would invalidate the guarantee (for what it's worth!). I bought Panasonic because of their reputation for reliability, and it was an "upgrade" for an 5-year-old Panasonic NV-G12 that has given good service. On the whole, I'm not really impressed with the FS90B - it cost twice as much (700 UK Pounds - discounted from 850), its ergonomics are poorly thought out, performance about the same as the G12 (when new) and it is (to say the least) rather unreliable. Panasonic - here goes your reputation... I'll let you know if I get any more information that might be useful to you. Meanwhile, if anyone has any suggestions about my machine, to quote the immortal words of Spock: "I am all ears"...
