With less then 50 games on my Batman LE seems like I've lost 6V to Node Board 8
Not really familiar with these board so question is are they repairable or do they need to be replaced ?
And could a bad connection cause this ?
Thanks in advanced

Definitely could be a bad connection somewhere. Game unplugged: Start by unplugging and replugging all the connectors to the Node 8 board(s). That's fixed similar problems on others Spike games.

Thanks for the suggestion
I sort of did that yesterday, with no luck
Power comes into 8 then out but doesn't light up the green 6v indicator diode on 8 ,rest of the boards seem ok and and green 6v indicator diode are on
Is the board fried ?

If you know for sure there is 48V power going to that board at the power connector but there is no 6V LED, that board is not powered. Is it dead? Unfortunately that seems likely. There is another thread here somewhere and that seems like a somewhat common failure.

Please see photo. think that will be your issue. You can buy the chip online and get someone to change it over for you. You will need to find someone that can repair smt boards. No guarantee that is definitely it as there may also be other blown diodes and chips as well. It is a voltage reducing chip. That is why you have a red light (48V) and no green light. 1st photo is a blown one, second photo is one from a working board.

If you game does not have the capacitors installed as per stern service bulletin and the stabilisation is not done, One of the legs on D9 may have broken off.

Or you can buy a new board.

Good Luck!
