RGB/Component Mod Dropping Color
« on: February 25, 2016, 02:32:56 PM »
I really had hoped my first post wasn't in this section.  I purchased a pre-modded Duo-RX that came region free and also with a scart and component cable.  I had no issues playing the first day, but then today after playing for 30min. I lost all reds in the video.  A reset of the console solved the issue for about 5min., but then I lost the red again.  Now, I can't play anything for more than 5-10min. without losing color.  I'd rather not have to send the system back to Japan if there are a few things I can try on my own.

You bought a modded system from Japan?

Probably from duojindance.

Most likely the mod has a loose wire.

I agree, it's probably the wire that attaches to the hu6260 chip. I've seen many rgb/component mods where there is hardly any solder on those wires holding them on or they are slightly bridged to another pin. If you have a friend who is good at soldering tiny pins then it can be fixed.

I can probably handle that myself, I just needed an idea of what/where to look.  I've done mods on a lot of other systems but decided to take the lazy approach with this, and well, now I'm paying for that.  Thanks for the feedback.

It may be difficult to fix as duojindance likes to cover his work in epoxy.

Sounds like a fun weekend.  I'll open it up tomorrow and see what I've got.  I just can't have nice things.

Oh man, it would suck if he epoxied that. Hope to God it fell off on the other end.

if it works for a min, its not a loose wire
i know on the duojindance RGB amps the input caps are installed backwards, due to the 6260 outputs having a 4V offset, but the amp inputs are only 2V offset
bad cap would do it in the amp

I trust this man's opinion. I would suggest checking the Cap in the amp.

Welcome aboard and good luck with the fixin'.  Le Steve knows his shit inside and out, so listen to him and don't hesitate to send it his way if you need to toss in the towel.

You can remove his epoxy with a hairdryer and patience

So before things got crazy, I decided to test it out on some different displays.  In short, no color drop on either of my LCDs.  The two Sony Wega CRTs?  Both exhibiting the color drop after some playing time.  My Omega gets some considerable time on the Sony and this doesn't happen.  I suppose not all amps are created equally.

I assume you are connecting the console with the component cables to all the displays you tested it on?  Have you tested RGB with the scart cable?
