more likely to be the pcb if you've no lights at all. have you checked the fuse, simplest things first. the puma pcb's burn out on the top left (rear) sometimes you can resolder the connections, sometimes the damage is too severe.
hiya marra i dont think bleeding the rads would help

I found the manual went through the troubleshooting chart and found the pcb was the fault so I removed it and just as you said it had burned out at the top left hand corner..I managed to resolder and all is now well and everything is up and running. do you know what causes this problem is it a dry joint or a bad bit in the circuit design???.weargas said:

baxi engineer told me that the puma pcb's are well past 14th generation.
how many tries do they need to get a pcb right? well, more that 14. kinda answered my own question there.
d'oh.
