How do I mod a 5200

[vintagegamecrazy]

I am looking for instructions or a faq on how to mod a 5200. My rf is weak and hazy and a good cable won't help so I want to mod it for supreme picture, let me know what to do.

Thanks

Look for this entry about halfway down the Faq

"4.13 - CHROMA/LUMA (COMPOSITE VIDEO) AND AUDIO OUTPUT MODIFICATION"

Have fun
