I have an Interact series 1 mk2 with TNC151 control and 12" CRT monitor.
Everything has been working fine for some years now until last week when the CRT monitor decided to pack up.
I have searched this forum and loads of other places about using a more modern LCD screen instead but can find no definite answers.
I have bought a GBS 8200 converter and whilst I can get some fleeting signs of a picture, it does not magically solve the issue.
I have been quoted GBP £930 for a plug and play Tsubis replacement!
It would be more sensible to upgrade to Centroid Acorn for the whole machine than buy that.

So, can anyone give me any clues as to how I connect my old 15KHz video signal to a modern screen please?

I am only a hobby user building steam stuff so I don't have to be back in production quickly but I need to resolve this problem - one way or another....

Thanks,
Les
