The power supply is a separate board on one side. 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.

Then get one, you will need it.

What exactly did you break on what I assume is the power supply board?

Also, per your first post, was the unit dead as in absolutely no lights & operation or did you mean it would turn on but nothing functions?

sorry if I come off rude but you need to post as a question rather than us asking you questions in order to help.

You need to tell us what you did, that the board was broken, which board, what flashing etc.

Worth mentioning there are a half-dozen pico fuses on the board that can (and do) blow. I always check these before going down the rabbit hole of resisters and capacitor testing.

Sorry to highjack but whats the PQ on these players like?
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?

I had one for too short of a time, didn't think it was bad but nothing special.

Grasshopper always liked the combo players, said the LD was a good version.
Again I didn't have it long enough.

Fully with laserfanhld-gb on the picture quality.

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.

PQ is average+, not great. DVL-91 S-Video did surprise me a little though.

Pros:
Fully loaded with features
Fast side change

Cons:
Sketchy power supply
Side B alignment
It is a DVD player that also happens to play LD

For the right price I would not hesitate to pick one up (well I guess this can be said for all players when it comes to me). Watch first 3 minutes of Side B before you pay. M-Holders in them alone are worth about $100.

Perhaps one of you guys can confirm this - didn't Pioneer configure its "HQ Circuit" function on these models in such a way that it defaulted to its enabled setting each time the unit had been switched off? I'm thinking unlike say a 925 or 2950 which had front panel buttons (inc.a status led on 925) it was even buried in a menu on the remote control....I wonder how many new to LD owners are running a 919 unaware that this image destroying function is automatically engaged and slicing away a good chunk of the available PQ? There are some recent screenshots on another thread which seem to replicate the extremely soft PQ that results when this dubious NR type circuit is used, in that case it wasn't a Pioneer player but the effect is similar.

I have DVL-9 DVL-909 and DVL 919 all 3 domestic JPN models , all 3 DO NOT have any PQ circuit feature which is remotely similar in concept or implementation to the one found in 925 which I also have. 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.
