White japanese PC Engine some problems and questions.
« on: April 08, 2009, 11:02:32 PM »
So a couple of days ago i received my third nec console...a white japanese pc engine.
Today I found some spare time to test it and have some problems...

sorry if all these are already answered somewhere, but I searched the forum for a bit and I couldnt find something ...since i'm new with it's kind of confusing with all the different names and version mentioned everywhere :P

So, the console has a scart cable coming out of it, i guess its an rgb mod, since i know it only had the rf built in.
Tried the scart on my tv, in rgb mode and plain scart mod....but i'm getting a black image. I can see some sprites of the game, but no colors and no brightness...

Seems like a bad/loose connection or soldering somewhere in the cable.
But before i open it to check the connections I wanted to read some things about the mod, can you guys gimme a couple of links with rgb mods for the pc engine, so i can find the problem easier?

Also, when I tried the rf, I got quite a nice picture, with bright colors and all, but didnt get any sound.
Did the white pc engine had capacitor problems? Should I get into changing them or is there any other known problem with sound that I should check first?

Last, but not least...the pce came with a british sega power adaptor. I guess it is compatible? Can I use any sega adaptor or do it need to have certain specs? The british one that came with the pce is 10v and 1,5 A... the european one I have is 10v but only 0,5 A...will it work correctly or it doesnt have sufficient amber to power the pce ?


thanks in advance :p

ok, couldnt wait for any answers since i found some spare time to open it.

First I opened the scart, one cable, the 5volt one was cut. Soldered it back in place, but still got the dark image.
Opened the console, checked all connections, everything seems to be ok.

Did some search....the mod on the console is actually the mod described here
http://www.mmmonkey.co.uk/console/pce/rgb.htm
the one at the extension pins.

I read about darker image being a common problem with this mod and the solution being the use of three transistors...
i'll try finding the transistors tomorrow and will add them tothe scart cable to check if the problem will be solved

feel free to throw in any ideas
