Firstly, i'd like to say a big thank you to everyone for the advice.

I have taken the RCM this morning. (tire pressure,oil, water etc is normally as far as ive gone, so this is an achievement already! haha)
As you can see, the solder in middle seems to look pretty bad so i am feeling confident this is the problem...I hope!
BUT as you can see from pic 3, ive been a bit clumsy and scratch the board. Is there a way of repairing this?

Thanks in advance
BC
