Localization Legend "Supper the Subtitler" has "joined the club" in being targeted for CD-pressings by bootleg master Tobias/PCEWorks! His projects like Private Eyedol, Galaxy Fräulein Yuna 1 & 2, etc. are now being sold on Chinese factory-pressed CDROMs...  |

6280 doesn't handle image at all
The picture is rendered in the 6270 and scaled and colored in the 6260
6260 does have RGBSHV available at the chip

I was able to mess with the unit today again and after messing with VR103 (turning it more CCW) Rondo now plays the music non stop. The Ys issue still persists (I'm going to trust Steve and maybe try to find a replacement motor). VR102 is functional but looks horrible. Anyway, work in progress but apparently is progressing well. Thank you for your input Steve and thanks NIghtWolve for summoning him 
I'll come back soon-ish with more details/progress report.
In a side question: Steve, would you know how the Huc6280 digital DACs work? I'm under the impression they receive the 3 bits for each color and just scale them to send the signal but I'm not sure. I'm asking because I'm trying to make a RGB->YUV color lut on the OSSC (I kinda got it working but the image is kinda yellowish and I'm wondering if its the signal getting scrambled somewhere due to noise or maybe I'm misunderstanding the DACs). Thanks once again

Note this is a standard Sony cd chip set
Any cd player using this chip set should have the same adjustment procedure

Also note the pot under the 2 caps (vr103?)
It's all the way right and shouldn't be

Vr102 may still work
Set your scope sync to left and the pattern looks ok
Im thinking you vr102 is all the way right and should be about center
The getting stuck issue if I understand what you're talking about could be a bad tracking motor (seen it a few times)

Hm, alright, I'll forward that to @thesteve (a PCE EE) and Keith Courage.

Wish I was in the US to get some professionals to do it :/ I'm in south america
I ended up fixing the audio and the caps (it was mostly leak capacitor on the board + bad traces).
My biggest problem now is the cd :/

Yeah... I see the VR102 damage, like someone took pliers and bent 2 ends together... Weird that someone felt the need to tamper with it... Can't imagine they even knew what it's for, what they thought they were gonna accomplish.
Anyway, sounds like there are too many problems and you're gonna have to hire a repair specialist if you wanna save it. Try @Keith Courage.

Hi everyone,
Found this a amazing community a couple of days ago after buying a duo and felt like I could ask for some help here, sorry if its not the correct place
So...I got this duo on ebay in November. The seller claimed it was recapped which led me to believe it was problem free
I went to play red alert (original disk) and I could play almost-normally but I felt that sometimes it took too long to read the disc.. Since I have some experience in electronics + soldering I decided to open it and immediately found the horrors committed to this beautiful system.
Lots of leaking capacitor fluid still on the board....close to the AV connector it was really yellow. Some capacitors soldered to non-working (now floating) pads. IC506 blackish (even the legs). C315 completely dead. Some vias fully black. The person kinda destroyed VR102. The list goes on and on](/forums/Smileys/default/eusa_wall.gif "Brick wall")
I cleaned whatever I could with a cotton swab and Isopropyl alcohol. I redid some soldering and connected the floating pads directly to their correct place by testing continuity where the traces led. Then I went to the CD.
I tried as best as I could to calibrate the pots by looking at the eye pattern following this guide (https://www.retrosix.wiki/laser-tuning-pc-engine-duo). It still not the best. On Rondo of Blood (CDR) sound test the sixth track stops but the disk keeps spinning. If I try to play Book of Ys, when I get to the talking lady on the first dungeon the laser moves totally to the right and gets stuck there (I have to manually force the track with my fingers in order for it to unstuck). If I turn VR103 CW it stops doing that but also stops reading and the pattern becames a fuzzy mess.
Can anyone give me some tips here? I tried the pots, the eye pattern on the scope looks kinda ok but this problem of getting stuck and the music stopping is very confusing (it sounds like a bad cap because it happens after a while?). Also when playing the CD the music is only coming out on the left channel....
All in all this was a bad experience but it is not completely ruined. I can play HuCard games fine and I was able to install a RGB mod. Thanks for any help

Hey Otaking_Enos, been a looong time since we got an introduction thread! I didn't think I'd see one again...
Welcome!
Both great CD games to have started. My Turbo Duo arrived with Ys Book I & II which I guess eventually led me to localize Ys IV!
Dracula X was recommended to me by store owners on the back of EGM/GameFan magazines so I bit the bullet and paid the $85 to get it! It was a leap/tough decision into imports because the US library ran out and it exceeded my normal pricepoint/range for what I was willing to pay for a game past $50, but I enjoyed Castlevania on NES, so I really wanted to experience the upgrade in PCECD! I rented all the US HuCards available, I was only left with buying options if I wanted to continue making use of the system.
I think its underdog status made it more appealing to me since I was the only one in the neighborhood for miles that knew about/had it. If not for the contest winning me a TG-16 with Bloody Wolf, I would've just stayed on the NES/SNES path. I didn't have the money to be chasing every new console on the scene, so I skipped Sega output for example with the exception of a friend once letting me borrow a Genesis for a bit.
