If the corrosion is minimal that would be quite normal and shouldn't cause any problems. If you do attempt to clean it though, i would be extremely careful as the pins can bend or break quite easily.

Maybe the solder of the rgb port has come a little loose ?

Did you try another power supply ?

Hi dougal, yes I have tried 3 power supples, including my 300w one from amigakit. If I open up + look at the mobo where are the soldering joints on the video port? Is the video port removable + replacable?

I don't think its the video chip as composite works fine


To check the joints you would most likely have to remove the motherboard from the case and remove the bottom shielding by undoing the screw things on each side of the connection ports at the back.

The solder joints will most probably be at the bottom part of the motherboard.

But don't quote me as i'm not sure.
