System worked, but I only got a b/w picture. That one was a light blue 407µF/25V made by GRAND SONIC. I have one board that boots to B/W picture when "cold". After some time colour pops in. It also quite often hangs (after some seconds) when cold. With time it also becomes more reliable. Voltages on the regulators/stabilisers look good. Don't have scope at hand to have some more close look but maybe this rings a bell for someone? -- SD! Message was sent through the cbm-hackers mailing listReceived on 2012-09-12 14:00:06
