Checked all the chips and they look fine and seated well. Do i need to replace the board now or are there any further fixes I could try?
I can't zero in on a simple fix here. Given your experience, I would tread very carefully and consider getting a repair guy round.
You probably have a short circuit/ pinched wire/ failed switch. But there are other causes of faults like these.

If you unplugged all the bottom connectors of the cpu and a fault remained then you definitely have a cpu fault. So go no further until u have it repaired.

Yes I have and the fault is still thereHave you tried what Andy suggested above?

Yet again.
uln2803 failure. The one behind the batteries. Take old one out.
install socket
Easy
if you cant do it. Then send the board for repair at @myPinballs or @philpalmer.
Can the mods terminate this thread. Getting silly and p@ss being taken now.

Thank you, I will send it or get someone round to repair. Am i right that this chip is soldered in. It's just not a pop out and replace? And if I send it off does it get tested before return? I still think it's strange in happened in the middle of a game just after I had installed the 5v board.
Sorry another question and me thinking out loud. The shaker motor was active so something may of come loose. Is it just a case of gently pulling on all wires under the palyfield? or would it just be on the coils etc? (feel free to face palm here I know to the maintenance side of things)

If it was me, i would be taking that silly 5v 'fix' board off and sorting the actual power board reset issue first, then seeing what's its like. For 5 row ground shorts to suddenly appear seems odd and points to maybe more of a 12v matrix (digital) voltage issue than anything else. Have you checked the voltages out of the driver board and the 12v digital voltage at TP3?
