DV tape in LP mode

[maximo4usa]

This message is for mynx "As a repair technician" (like you said) or for anybody is interested.

I have a JVC gr-dvx7 PAL miniDV from one year 1/2 now.

When is first start using the camera i really liked the LP mode (record 90 min video on 60 min tape) so my first tapes are all recorded in LP.

Now i'm having "sometime" a problem playng back those tapes becouse the camera produce pixellation and flashing color and strange effect. The really strange thing is that it does NOT do this everytime.
I have noticed that whenever the room temperature is cold (like 5-8 grades) the camera produced this defect and i'm not able to view correctly my video that is all disturbed by those giant flascing pixel multicolor.

I belive that the tapes are fine and not rowind becouse sometime happen that (maybe with a wormer temperature) the camera play those tapes just fine (no problem).

So ... i'm confused... is the camera damaged ? is it supposed to be like that ? why do i have this problem only in LP mode and not SP ?? Is anybody else having this kind of problem in LP mode ?
I bought my camera during summer season, so again i guess i never had the pixellation problem becouse the warmer temperature ??? or becouse the camera was new ??


Can someone help me and tell me a reasonable explanation for this problem ?

Thanks in advance

Max


PS: The camera work great in SP mode in any situation or temperature.

I have never heard of that problem but I would quess that the camcorders tape tension setting is off. Jvc told us that is the first thing to check when there is a quality problem. It reqires removing the mechanism however to check/set it. Also do not use the 90min tapes(SP) these will not work in a JVC camcorder reliably.
