Title: PAL RGB horizontal bleeding and story of now defunct Core Grafx!
Post by: SuperPlay on 11/29/2012, 03:59 PM
Hi Folks

I had an issue with my Core Grafx displaying horizontal bleeding via RGB.  As seen with the whites here:

Looking around the web I noticed that some scarts have 200uf capacitors on the RGB lines, so I gave this a go.

This fixed the bleeding issue, however the picture was washed out.  So I had the great idea of trying some lower rated capacitors. The only ones I had were 10uf.

This is where things went wrong!  With the 10uf caps the output flashed pink (no game displayed) and now that the caps have been removed I only get a flashing white screen.  (caps were installed with correct parity)

Not sure why but it seems that the lower rated caps killed my Core Grafx :-(

Doh!
