Default Re: Microvitec Cub 1431 Power but no picture.

That sounds like the PSU is OK but being loaded down by the line output. Before spending time on anything else, check for a short on C306, the 24V flyback supply reservoir. You can test from above the board between the field shift link or the end of R313 and ground. Those orange ROE caps are a liability and it is worth changing that and C308 too.
