Hallo all. I just bought my first MSX - a Sony HitBit HB-75B (I'm in UK). What a thing of beauty it is, inside and out.
I grew up with Sinclairs and Commodores and have always wanted to try out one of these mysterious Japanese machines The build quality is absolutely insane!
Anyway. It's in lovely condition and I've spent the weekend meticulously cleaning it (partly to fix a couple of dead keys) and it's sparkling. Only one downside - I'm stuck with RF for the video because the RGB SCART really isn't wanting to play ball.
On SCART, I get a slightly washed out (and too cyan?) picture that cuts to black every second or so (at most). When it is on, the picture is sharp, albeit covered in jail bars. Looks like this:
It's off rather more than it's on.
Hardware wise, I can't see much wrong at a casual glance. Solder points are good and clean, I ran continuity on the 21 pins and they're OK. The TV can do RGB SCART well (in 50 or 60hz). Sadly I don't have an oscilloscope so I didn't want to touch the variable resistors inside.
It's not the end of the world if I can't fix it - my TV does an OK job with RF (pictured below) but the SCART socket was one of the reasons I went for the HitBit in the first place :( My standby would be to build a composite cable and run it into my Retrotink, but that's hardly RGB.
Any thoughts? I'd value absolutely any input. Cheers!
