PANASONIC NV-S7B Camcorder - dodgy dew sensor
 
Like many Panasonic camcorder owners - the dew sensor on my NV-S7B has
packed up. Since the cost of professional repairs outweigh its value -
I'm hoping I might be able to fix it.

I understand from some postings - resoldering or shorting the sensor
can resolve the problem.

1) Does anyone know where the sensor is / what it looks like? It's
definitely not part of the power/record cable as with some other
panasonic models.
2) And then - how do I disable / fix the sensor?

Regards
Tim

If you can find it, and it is connected via a connector, remove
connector and solder directly the wires to the pcb. conn develops hi
res contacts and causes the problem.

It's usually near he video head drum. It's a small maybe 1/8 inch
square with two wires going to it. On the surface of the square you may
be able to see a continuous back-and-forth conductor covering most of
the surface.

I know what dew sensors look like on other models but I'm still
struggling to find it on mine. I can't see anything similar - but much
of the cicuit board is hidden. I might have to start taking my
camcorder apart and having a closer look.

(to clarify lakewood's solution above) Once I find the dew sensor Do I:

1) remove the sensor, or
2) remove it and solder the two contacts together to complete the
circuit

Problem solved.

Joining the contacts together prevents the dew sensor activating.

Have jpegs if anyone wants to know where it is.
