- Do you notice any odd effects if you use a "slow motion replay" mode? Any
- differences in SP/LP modes?
-
- 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"...
