I need to find someone familiar with the Panasonic AG-W1 VCR.

I am trying to repair one and I need some help please.

The unit have a conversion problem between format (NTSC/PAL/SECAM). It work
in past trough mode, but is did not always switch to PAL or SECAM, sometime
it does but resulting in a out of sync picture, with no color (and Yes I
have an multi format TV to test it).

I may have find a potential cause for the problem, but I can not be sure, I
can not figure out the use of a certain section of the circuit and I am not
sure of what it's suppose to do. Is-it performing correctly I do not know.

Bye
Jacques
