Thanks Nino
               No it doesnt boot to audit mode interconnect board plugs have been replaced on the Driver board but not on the CPU was the only working board on the game and hoped to not have to touch it LOL.

   Looks like it will have to come out Thanks Nino

Looks like it wont be leaving anytime soon   

I'd at least try the interconnects first. Even reseating them might "fix" the problem. General rule of thumb with sys4/6 - replace interconnects and the 5V cap on the power supply.
