You don’t need to remove the tray. It’s a switch mode power supply. It has one large capacitor. Start with that. You will need a multimeter to measure it. If that checks ok, the issue is in the feedback loop. It’s complex. Either try to source a working power section from another 919 or look for a repair guy who can repair circuits rather than swap parts. You can also watch videos on how to fix switch mode power supplies and self taught yourself.

These DVD/LD players seem to appear very often in New Zealand Considering that you own a CLD-R7G I would imagine you'd be a little underwhelmed with the LD PQ Jake, the DVD side is no better either and it's PQ was only regarded as average at best by AV mag reviews back in the day. Can only speak for the European PAL/NTSC versions (with an E on the end) but probably still applicable to the US and JPN variants although I'm guessing NTSC LD PQ could be a tad better on these?

Had three PAL/NTSC versions & one NTSC version pass through my hands over the years & the picture quality is very soft indeed. I personally was very unimpressed with them, nice looking units but not great as LD players & the DVD bit was also rather poor. If cheap & fully working though might be good to have as a back up unit.

There is a noise reduction menu in both 909 and 919 which is basically the same machine but in reality it does almost nothing to the PQ of a regular LD and doesn't work at all for DVD. The only kinda useful feature is chroma noise reduction but the actual difference between the default and an adjustment be it "more" or "less" it too small to even bother. DVL-91 is a bit different although its hardware is 99 % the same as 909 (and software is the same for both). Three was a popular (?) hack back in 98-99 to mod the 909 into the 91 which would enable DTS playback and that more advance video features menu but again, it won't do much to the PQ. Hi, thanks for your post. I think what you say regarding the US & JPN 909/919 players is correct, it is only the European PAL/NTSC 909E/919E variants that featured the HQ Circuit function from what I've read.

I very much doubt is as the firmware (software) is the same for all region versions regardless of obvious functional and hardware differences narrowed down to PAL LD playback and SCART support for both EU version and the complete lack of it for the rest. Same goes for the IF con firmware which means the menu system is unified for all versions and there is no specific menu driven function to control the "HQ circuit" - all the version feature the same NR sliders and 3 playback modes which in reality differ only in contrast and saturation levels. If I remember correctly there is also the black level toggle in DVL90/91 which is designed to comply with the US and JPN NTSC black level values of 7.5 and 0 IRE respectively. but this feature is not present on lower models. The single button HQ playback on the 925 is geared mostly towards PAL sources and actually adds very little if any "HQ" to the NTSC LDs.
