I think the Diagrams are pretty self explanatory but, if you have any problems just ask. =)

The Mod you are talking about in your link only works on PAL A520's Not NTSC.

In truth, the hack works on both modes, you just need to use the correct encoder's NTSC/PAL pin. :)

Ask me why! :mrgreen:

Thats Cool I didn't know that. =)

My Mod Isn't PAL or NTSC Specific Actually. Also, I think That the Mod I did is a little easier.

Re: A520 S-Video Hack For NTSC

It is, but you need to tweak the R, G & B resistors to match perfect colour balance. Better use 3 trim-pots there (hint! hint!).

Thank you for pointing that out. I have made a correction to my original diagrams so that the color is more balanced. If a person wants, they could use trim pots instead of the resistors for the RGB Lines. I have also made a correction in the resistance from the Composite Sync. This should clear up any issues with the colors having shadows.

There is also a new pic in the Zip File that shows my A520 with the hack done.

I seem to be having some trouble with this design. after you mentioned color balance I looked further into the color problem and realized that the color looked kind of washed out. I can't understand why it's like that. any ideas why it looks that way?
