Vertical lines on Plus

(1/2) > >>

Hi! I have these machines:

CPC6128, no problems... great picture
6128PLUS on RGB on a TV it gives me heavy vertical lines issues, very annoying
464PLUS on RGB on a tv gives me also vertical lines, but not too much as the 6128plus

I'm using a RGB scart cable from retrocomputer shack and a jamma power supply for the 5V line

Any idea? thanks

Hi,
     yes, it's due to Alan sugar scraping the last penny of profit out of the machine and removing the capacitors from the RGB outputs. Not noticable on a CRT, but it shows up on modern TVs. More info here: Dirty video on 6128 Plus RGB Scart

Kris:
Each Plus owner should apply this fix; it's a shame to have a video signal output without "filtering" ;)

Mine actually suffers from this... I should fix it, but I am considering to use a proper CRT instead  :-X

So, should I add a 'star' of three 220 pF capacitors from ground to each RGB line?
