Default Re: Sanyo VTC 9455 Betamax - No colour

So, I left the VCR turned on for an hour and tuned to a channel and I finally managed to get colour out of this thing but only from the tuner! I can select between PAL and SECAM and the LEDs light up but it's still black and white when playing tapes. To me, this definitely seems like a capacitor(s) issue. What do you think?

Hi.

I am just trying to envisage what the size of the VCR would be if it were to proclaim "Discrete Electronics", probably something like the size of a gas cooker!

Well, here it is. It's just a 9300 for the Middle Eastern market.

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
