8-bit acorn hardware • BBC Master Compact Font Wierdness

Gday,
I have restored a BBC Master compact, but have one outstanding issue still.
When powered on it randomly show a corrupted display font.
when compared to original.
It is totally random, and worse when using a walwart. I have replaced the electrolytic caps, but still issue occurs.

Any ideas from the brain trust.

Thanks in advance
