Panasonic NV-SD400 jams electronically.

[Rus]

Hi,
A friend and I both bought the same model video on the same day.
It was the Panasonic NV-SD400
About three times a year one of them jams
and half the functions are lost until unplugged from the mains for about a
minute.
The channel numbers change on the display but the tuner stays on the same
channel
and the menu does not come up
though it plays tapes.
Anyone know about this one ?

Since reporting this problem
I have learnt of a cure on the Panasonic website.
The BSX 0875 kit.
