Hello.
I hope someone here might have some hints and tips to fix this problem.
I'm fixing up a pile of A1200 motherboards, and found one that initially didn't work. After changing an obviously bad cap (C459) I got it working, but no image on RGB.
I could tell the board posted by the floppy idle clicking sound. No error flashes on the LEDs either.
I had the board connected to a TV via RGB which flickered slightly when powering on, but no Kickstart image.
So I connected the Composite and got an image.
The picture was very off colour and had interference in the middle of the picture. I removed the RGB cable and this improved the stability, but it still remained off colour.
I will of course continue replacing all the caps, but is there something else I can check regarding the lack of RGB output? I didn't try the RF output yet, will do soon.
Could the Composite and RGB sync cause this issue?
