Philips vcr s-vhs vr813 or vr8139

[yoyofr05]

Hi

I have the following trouble on my s-vhs philips vr813/vr8139
(pal-svhs/secam vhs)

Twice systems give a good picture (color is ok in vhs secam mode but only black and white in s-vhs pal mode.)
The install menu is not displayed on my tv set but ok on the vcr display panel.
thanks for any solution to solve the problem.
b.regards
