MZ-80K screen distorting at the top

Post by traindriver69 »

Hi all
I have been working on getting my MZ-80K working and I have now got it booting up and on the screen it is fine for about a min then the screen starts pulling at the top getting worse and worse buit if I turn it off for a short time its fine then starts again.
Anyone have an idea what maybe breaking down will it be on the CRT board or computer board any help would be much appreciated.

Something is warming up and shorting (or breaking). Most likely a capacitor.
