Console Repair/Mod Center
I picked up an RGB amp + 8Pin DIN + SCART cable from mickcris and needed some help with it. I'm pretty convinced that mickcris sells exceptionally well made stuff, so I'm assuming the problem may be on my end.
So I followed the standard procedure and tapped RGB from the HuC6260 chip, wired the signal through the provided RGB amp, and coursed the signal through to the 8Pin DIN I also got from mickcris. (See below)
The signal comes through, but these are my problems:
INTERFERENCE: there seems to be a bit of scrolling interference. Like snowy waves scrolling up and down. I'm using a switching generic power adaptor that outputs 9v, and I'm aware that the PAD-124 (official NEC power supply) needed 10v. I just ordered a PAD-124 and when it arrives, i can check back to be sure. But does anyone know if there may be another fix besides the power supply? Anyone had a similar problem?
GHOSTING: There also seems to be some problems with the integrity and clarity of the pixels? I also have a SEGA MD/Genesis which outputs in RGB, and comparing both MD & PCE Duo seems like night and day. Let me first say that I know that composite is much worse and the signal I get from RGB is much cleaner, so I'm not being ungrateful for this newfound clarity - RGB is amazing. But what I get on the Sega MD is pixel-perfect sharpness and incredible clarity, nearly like playing on an emulator into a monitor. The PCE Duo seems "ghostier" and I want to know if it's that: 1. The PCE's image processing for RGB isn't as good as the MD; 2. Are there capacitors on the board that need to be replaced (I already did a cap replacement on many of these old caps)?; 3. Could it be something with the components from mickcris?
SCART CABLE PROBLEMS: So I followed the photos and instructions given by mickcris and wired the right pins as properly as I could, but for some reason the SCART cable I got from mickcris doesn't work. I used another SCART cable I purchase from an eBay seller (retro_console_accessories) who provided me with my Sega MD/Genesis SCART cable. That cable works, and so I assume that the RGB pinout aligns with mickcris' pinout in his instructions. Sound and image both come out fine (with the noise interference of course). But it seems like the SCART cable from mickcris won't work. I followed his B-G-R label (see the 1st photo) from the instructions, so it's strange that another seller's SCART works, but his doesn't. Any help with possible differences in RGB 8pin DIN layout?
Any help would be most appreciated. Mickcris has been very helpful thus far, and he is a trusted member of this community. He advised me to post it here to get a discussion going and possibly find out where the problem lies through discussion. Thanks, everyone!!

No joke. On October 29, 1993, "Akumajo Dracula: Chi No Rondo" was released on the PC-Engine in Japan. I don't believe in coincidences.
