[Console Repair/Mod Center / Re: PROGRESS on CD-ROM² Repair]

fixed.
super system card on Everdrive + SCD + CDromrom = don't works.

[Console Repair/Mod Center / Re: PROGRESS on CD-ROM² Repair]

Hi guys, I use this topic to avoid opening another one. I decided to bring back to life a dead  CDR² unit. I know mine had a middle gear issue, and send my regards to PC Kid from the French forum dedicated to NEC consoles, who provided me a new gear, that he made with a supplier he know. The easy part with the old one is it turn into dust very quickly with age.

Once done, I removed the little plastic chips stuck in the grease, check the complete rotation of the new gear and I used a original game and I did face to the "Wait a Moment" issue.

Ok so the CD spin it's a good point, but I decided to test first an audio CD, TesseracT - Altered State 432hz, tracks are detected quickly then only scratching noise when attempting to read then stop quickly. I decided to adjust directly last pots while reading.
For that I removed the bottom case, put down an isolation paper to avoid short and give it a try on VR105.

the audio came back and the reading seems smoothy with less mechanical noises.
I did try a CD game (Spriggan) with success but I encountered some issues with SCD.
With Deden no Den I had Macroblocking picture right after launching the game and with Emerald Dragon green screen.

I think I'm not too far from fixing it, and I think perhaps I'll have to check again the VR105 (Voltage control oscillator, right ?) I can have an oscilloscope for testing RF pin, so any screen example will be appreciated.
Thanks.

We definitely don't want to release a half-completed translation just because some people are impatient. Too much time and work has gone into this for that.

It shouldn't be too long ... the web-pages made great progress this weekend. 

it's not about impatience, just personally I prefer the Japanese acting when it's related to voices.
the top would be to release a dubbed and no dubbed version as you mentioned it.

[Localizations, Games, Apps, Docs / Re: The Official Emerald Dragon Translation Project]

You're right, so in order to don't be totally off the topic, I'll reply you, the both.

[Localizations, Games, Apps, Docs / Re: The Official Emerald Dragon Translation Project]

Do you consider releasing as it and giving just some translation sheets for the dubbing part ?

[Buy/Sell/Trade / Re: Turbografx-16 & PC-Engine Reproduction Hucards Now for Sale!!!!]

Actually we were already working on this before stumbling across ichigobankai's post.  Thesteve already started on the layout before I saw ichigobanki post.  However having ichigobanki's cards on hand did helped on the programming aspect of it.

Ichigo worked on it since at least April 2014 on a french website (and at the time he worked on it for a couple of months).

[Console Repair/Mod Center / REPAIR GUIDE - Super CD-ROM²: Total Capacitor Replacement Chart]

I don't understand why people don't use SMD electrolytic Cap with same footprint as original, make it simple dude !

[Console Repair/Mod Center / REPAIR GUIDE - Super CD-ROM²: Total Capacitor Replacement Chart]

nope, it was a problem with the sodipeng amp not wired, so is problem fixed for RGB, but still a little sync problem, when CVBS is connected directly from expansion port to SCART 20 it works (original wire from DIN cable is removed), when cable is normally use and a wire cabled between expansion port and pin 3on the Din there is some deformation/waves on a side of the TV

edit: fixed.

Another one.
Lens go up and down, beam is visible then "set disc" message ?
The SCD² was recap by a non professional of the job.

[Console Repair/Mod Center / REPAIR GUIDE - Super CD-ROM²: Total Capacitor Replacement Chart]

Hi guys,

I try to help someone who did recap a SCDR² and it doesn't work in RGB now.
the cable works fine with the core.
I asked him to try simple link from expansion port (with its Sodipeng cable)
there is just CVBS for sync, 0V and 5V for fast blanking in Scart 16, then 2 colors through the Sodipeng.
here are the results the colors are added and saturated there is no additive colors.




the CVBS works fine when pin 16 is removed, all in grey with 3 colors when plugged.
Any idea ?

[Console Repair/Mod Center / REPAIR GUIDE - Super CD-ROM²: Total Capacitor Replacement Chart]

Did someone have the schematic on the power supply from jack socket to 7805 input, from what I remind there is a power diode, then a PNP mosfet and NPN mosfet with some zener diodes.

[Console Repair/Mod Center / Re: Help With Pots Adjustments]

Yes, such guys are jewels to the community.

[Console Repair/Mod Center / Re: PCE CD-ROM2 - Where to start?]

cleaning and put new grease perhaps.
The Flat Ribbon is not inverted if the console was ever unmounted ?

[Localizations, Games, Apps, Docs / Re: Anearth Fantasy Stories - Translation Project Thread]

any news on the WIP ?

[Console Repair/Mod Center / Re: PC Engine Duo audio problem]

probably damaged trace or via.
cleaning needed.

[Console Repair/Mod Center / Re: Turboexpress LCD mod take 2 - rolling screen]

which sync signal do you use ?

[Console Repair/Mod Center / Re: PC Engine/Core Grafx 2 Hucard slot/board not working]

Why looking to this while you found that the problem came from your Huc connector ?

[Console Repair/Mod Center / Re: Did I fry HuC6260? LCD mod fail]

normally no, some friend fried fuses on PC engine twice without further problem on chips.

[Console Repair/Mod Center / Re: Duo-R - Disc read issues, yellow HuCard screens, corrupt graphics]

So, it's not your connector but a dying Huc.

[Console Repair/Mod Center / Re: PC Engine/Core Grafx 2 Hucard slot/board not working]

misalignement probably.

[Console Repair/Mod Center / Re: audio buzz question.]

bad traces of bad soldering.

[Console Repair/Mod Center / Re: audio buzz question.]

Call me crazy, but I observed this:

More intense/greater amount of "white" (lighter colors) on CRT screen --> more pronounced buzz/high-pitched whine.

Buzzing is not just due to the intensity of "white" displayed on screen...but it is a factor, perhaps.

I am sure the gurus can explain why this happens, in addition to crosstalk (and _____ and _____).

I agree, white is 0.7V level on analog video (the higher voltage) perhaps there is coupling on audio

[Console Repair/Mod Center / Re: Duo-R - Disc read issues, yellow HuCard screens, corrupt graphics]

for the Huc glitches, I'll go for reflowing Hu ic's, ram and connection port

[Console Repair/Mod Center / Re: PCE help diagnose video problem]

picture you provided is too bad quality to see if there some shorts.

[Buy/Sell/Trade / Re: for sale: RGB mod chip]

2 sold.

[Console Repair/Mod Center / Re: No video/audio through Super CD-ROM² output]

mmm... I would worry about cleaning old parts this way for long terms issue (porosity ? humidity ?) perhaps for no reason

[Console Repair/Mod Center / Re: No video/audio through Super CD-ROM² output]

I think it's better to use isopropylic (exact english name?) alcohol, but nevertheless it works.
I hope for you it'll keep this way.

[Console Repair/Mod Center / Re: PCE help diagnose video problem]

Do you try to reflow this pin ?

[Console Repair/Mod Center / Re: PCE help diagnose video problem]

I have a weird PC genjin 2 which make some glitches with incorrects backgrounds like you.
As you don't have another Huc, I think that it could really be the source of your issue.
Get some Huc to confirm.

[Console Repair/Mod Center / Re: No video/audio through Super CD-ROM² output]

I should have a complete scheme for this one, but I can't have a look before next week.

[Console Repair/Mod Center / Re: No video/audio through Super CD-ROM² output]

you should have twice less minimum at cold, and a decrease as soon as the time goes by.
Follow the trace from the via under the cap and clean it, there is perhaps another issue.

[Console Repair/Mod Center / Re: No video/audio through Super CD-ROM² output]

Check pin 4 on CN103 connector, the voltage should be as low as possible to 0V. According to the result, probably the 1000µF capacitor next to the heatsink leaked on a via located under this cap.

[Console Repair/Mod Center / Re: No video/audio through Super CD-ROM² output]

Here are the Values I measured once for a fixed one:

1: 8V (V supply)
2: 3.4V (input 1)
3: 3.1V (output 1)
4: 5.52V (Vréf)
5: 8V (Low pass filter)
6: not connected
7: gnd
8: 5V (volume control)
9: gnd
10: 2.8V (Balance control)
11: gnd
12: 5.52V (wire to 4)
13: 3.1V (output 2)
14: 3.4V (input 2)

It seems that you have to check the traces on your supply pin.

[Buy/Sell/Trade / Re: for sale: RGB mod chip]

Free shipping until end of the week.

[Console Repair/Mod Center / Re: PCE No Audio]

Do you use a Scart ?
wire unplugged in it ? pin misalignement ?

[Buy/Sell/Trade / Re: for sale: RGB mod chip]

1 sold.
And Bump.

[Console Repair/Mod Center / Re: Pot replacement original Duo]

I think VR102 is next to the 10K-18K range, you have to measure pitch between legs to search which one could fit (I suppose many could). I don't know how many turns are capable of the OEM trimmers, but if you wish set it precisely, it's a parameter you have to take in count.

[Console Repair/Mod Center / Re: TG16: Shorted wires at the voltage regulator]

Curious that the chip was damage.
I know someone who reverse 5V polarity from a PC engine to my RGB board on expansion port and it blow the fuse.
Hopefully there was no damage on the console nor the amp of the board.
did you check your 5V is correct ?

[Console Repair/Mod Center / Re: Duo Repair Gone Bad, looking for suggestions]

Great !
another one saved from the trash. (A mod should update title with fixed)

[Console Repair/Mod Center / Re: Duo Repair Gone Bad, looking for suggestions]

If your regulator output 0.4V, you surely have a short circuit.
Check it off with ohmeter. If it's after your recap, I'll have a look on it.
