Default Re: Sanyo VTC 9455 Betamax - No colour

Good news. I changed a couple of caps (4.7uF and 10uF) on the chroma board and after a little adjustment of the pot, I got colour working fine on PAL (1st attachment) and SECAM (2nd attachment). But when playing an NTSC tape (3rd attachment), I get that weird rainbow effect on the picture. The tape that I played is a pre-recorded movie on Beta hi-fi. I read somewhere that Sony reduced the chroma bandwitdth in order for the hi-fi audio tracks to fit on the tape, and that causes incompatibility when playing Beta hi-fi tapes on regular Beta machines. Can you confirm that?

Regards,
Fivos
