britony se 80 pcb replacement?

3yrs ago had code 60 fault on my se80.got a new board which i set up as the original board and fitted it.combi has ran fine until last week.code 60 fault is back again.i purchased a new board but it is the the latest replacement type with extra pots and jumpers.have set jumpers as jp1-ff'jp2-tpr,jp3-3/3,jp5-atac,jp6-atac. i powered up and unit ran but ignored programmer.i then isolated power and shut gas valve so i could tidy wiring etc.after turning on gas and powering up the unit sounds as if it's going to light but brings up code 70 80 no flame and the red no flame led.if reset is pressed it cycles through the led's but again shows 70 80.[i put the original board back in and this only shows code 60.]can anyone out there give me any advice on the new type board or see where i'm going wrong.cheers.
