8-bit acorn hardware • Model B issue 4 video fault

Hello,

I have an issue 4 model B, it's connected to a TV via a scart / rgb lead. (I know this is ok because it works fine on another BBC B)

When you turn it on, it powers up as expected. BUT the text on the screen has, what is best described as Snow effect, The text has flickering pixels in it. Not the whole screen just the text.

You can use the machine ok, but the continuous flickering inside the letters on the screen is really annoying.

It does improve as the machine 'warms' up, but it's still there, just less.

Anyone seen this before, or ideas?

Derek
