Hi Thanks for getting in touch, the green screen is green all the writing & Icons are like embossed onto the screen A bit like the BBC on flat screen with wrong lead, I cannot get a decent picture of it as it comes out green with black but the black is not there looking at it, I have re soldered the resistors to the motherboard that looked a bit dodgy when I cleaned it but it was the same without them, scart plug image attached.What picture do you get if you press the green button on the monitor (IIRC it works by killing the blue and red channels, so it might give a clue as the problem is with the green signal).
Also, SCART cables for the BBC usual contain resistors to reduce the TTL 5V signal to 1Vp-p analogue RGB. I suspect these aren't needed on the A500 (since it should output an analogue signal anyway?)…
