* I would first check if all the PCBs are receiving at least +5V.
* I would clean the power connectors (male and female) with isopropyl alcohol.
* I would clean the sockets on both CPUs and program ROMs (everything on the socket) with an eraser or a glass fiber pencil, and see if that improves the result.

Are you able to enter into the Diagnostic menu by pressing the Test button and then run a memory test?

This era of Sega boards are littered with Fujitsu TTL IC's which are notorious for failing, so there's a high probability that one or many have gone bad and will need to be replaced.

Either a psu/ wiring error or a bad main board

Is the game running, or is this a static screen?

Not to hijack this thread, but do these boards have any security?
If so that might be it.

Hang-On uses normal Motorola 68000 CPU's (which you can see in the Op's photo), so there is no security or decryption of ROM's required.

So one could convert to any other game.
Not that there's more than 5.

No. This boardset is unique to Hang-On. Enduro Racer and Space Harrier are very similar, but definitely not compatible or convertable.
