Today has been a fun day. Got my DC out of the loft to ensure it still works - Have plans to turn our spare room into a Retro Gaming room.
My wife even wants to get involved
Unfortunately when I switched it back on I was met with a blue tint to the screen. Considering it has been in the loft for a while I decided to strip it down to check everything was ok inside (and to give it a thorough clean out).
This is the mid way point:
It was not pretty inside (aged dust = not good). Overall though I could see not obvious damage to any components.
Anyway after putting it back together I am pleased to say that the blue tinting now only happens in frequently. I don't know if the console is on its was out, or whether I just need a new AV cable (currently using RGB scart). I think I will get a new VGA cable first, if that doesn't work a "new" console. Either way I will benefit from the clearer picture.
