If you read my post, I explain where I get sync from.

The offbrand cable has all three wires for R/G/B and it also has a composite video wire. I have a PVM that accepts composite video as the sync signal (this is standard for SCART displays to use composite video for sync).
The PS1 SCART cable only needs three capacitors. The sync signal (in this case, composite video) is wired straight through. As far as the gamecube, the PAL models need caps on the RG and B lines, but it also needs a resistor/cap on the composite video line for displays that only use the composite video input.

So, does that mean I can just rip out the 220ufs from my SCART cable and apply them to the RGB of a GameStop Component cable?

I'd just buy some 220uf caps, they're usually around a dollar a piece at most. No need to cannibalize your scart cable.

As far as if you can use a cable like the one I made, does your TV take RGB in on BNC or RCA jacks? or is that just a component input? A hi-res picture of the inputs available on your display would help.

Well the battery in my camera is exhausted so I'll just list the inputs like so;
(One connection per input)
USB
HDMI
VGA(PC)
VGA(PC) Audio In
SCART
CI CARD IN
COAX Audio Out
Component (HD):
-Composite White (L-Audio In), Red (R-Audio In) & Yellow (Composite Video)
-Component Video (Red, Blue & Green)
RF IN
Headphone Jack

Input Selection:
FREEVIEW
ANALOGUE
SCART
COMPONENT
DVD
VGA/PC
HDMI
VIDEO (Composite)
USB MEDIA

Will give an image when the battery's charged.

It probably won't support RGB on the component then, unless there's a separate plug for sync. You're probably stuck trying to clean up/get/make a quality SCART RGB cable.

You sure? The Component I'm using for Wii & PS2 are Red, Green & Blue cables. But I guess we could try the SCART cable option. Maybe even go back to the Sync Strike option if I don't need a scaler or if it doesn't get too out of budget. I could get one of the cables bmoc suggested.
Here's the Component setup by the way.

Just becuase component uses red, green, and blue cables does not mean it's an RGB signal. It's acutally far from it, and more similar to S-video (Y/C).

Component consists of Y Pb Pr (or sometimes called Cb and Cr). The Y (green plug) is luma (the brightness info, it looks like a black and white picture) and the other two carry a split of all of the color information.

RGB (such as over a scart connection) is -actually- the red/green/blue information carried each on their own line. It requires a separate wire with the sync information. Basically no displays in the USA accept real RGB at 15khz (with exception of PVM/BVM commercial monitors, and some REALLY old computer monitors. That, and arcade machine monitors.). VGA is a type of RGB signal, just with higher refresh rate(s) and resolution(s) available.

Yeah component is not RGB.

To avoid a long unnecessary tale, just remember consumer TVs in many parts of the world are inferior to Europe.

Hence why I was clear to use the word "itself".

Just to sum things up from my perspective, I would recommend the following:

1. First and foremost, buy a new PS1 SCART cable. As others have said, it sounds like yours is wired for composite instead of RGB. It is not that expensive and will be much easier than trying to fix your cable.

2. Don't buy a Sync Strike if you aren't going to get a scaler of some kind. The Sync Strike is going to output a 15khz RGB signal that most modern displays won't recognize on their VGA ports. I didn't need a scaler because I am using an older CRT that can handle 15khz (this was the source of my earlier confusion and bad advice - sorry about that)

3. If the new PS1 SCART cable does not improve the image then you are out of luck on the RGB front unless you are willing invest in a scaling solution. Here is a rundown on some popular scalers

If the new PS1 SCART improves the image but the sync signal appears to be off then a sync cleaner is needed. You could build one into your SCART cable if you handy with a soldering iron http://www.mmmonkey.co.uk/composite-syn ... er-lm1881/ The LM1881 is the same device used in the Sync Strike for cleaning the sync signal.

4. If the new PS1 cable did not improve things and you still don't want to invest in a scaler, then I'd say a decent s-video to SCART adapter will be the best value for your money. A good s-video to component/hdmi converter will be expensive and you'd be better off spending your money on a scaler.

5. Another option would be finding a old CRT TV locally that accepts RGB via BNC or SCART. If you are patient, they can be had for very little money. I got mine for $50.

I hope this clears things up and does not add to the confusion that I caused earlier.

Well OK, I'll try to get a new SCART cable first (one of the cables you previously mentioned). And after I'll try to follow accordingly. Thanks a lot!
