A500 RGB-SCART Cable Colour Problems

j_sntos · 03 May 2012, 14:23

Hi guys, i've received today one gold rgb-scart cable for my A500 bought it from ebay.uk, but it seem that i have a problem with the colour on my living room lcd. When i'm turning my A500, on the main screen with the hand grabbing the floppy disk, the white colour is changed by the violet, and on the games is the same thing. Can anyone help me with this subject. Cheers

Green RGB color component is missing. Bad connection, broken wire or bad soldering (green wire shorted to ground inside connector)

I don't know if this is your problem, but I had problems with purple color (see attachement) with an RGB cable I bought. To fix the problem I replaced the resistor on the blanking-signal (pin 22 on Amiga-side to 16 on SCART-side) from 150 ohm to 560 ohm. This because the result is supposed to be between 1-3 V. The cable was matching this page (and this page is wrong): http://www.hardwarebook.info/Amiga_to_SCART

A supposedly better one (I haven't tried it): http://eab.abime.net/showthread.php?t=47281
