Hi Jim thanks for the info. Do you test those mains filter caps with ESR? Im thinking mine are ok with the ac voltage readings I get because they are after that, or would I be wrong to assume that?
I may buy the replacement board but am really only using the set as a learning project.

they're used primarily to filter out line noise and ripple from the mains supply and since they're across the supply you would still get your 220-240 input voltage but excess ripple will effect the supply. The best way to see if they're faulty i've found is to stick new ones in, they're inexpensive and easy to fit

cheers. I may buy the replacement power supply soon and hopefully get it up and running. Need a tv for when I get back onto my xbox 360 repairs.

Hello everyone thanks for the help you have given. I would just like to update you all, I have bought a replacement power supply board and all is working fine. I did originally want to find the problem, repair it and learn a bit. So I have a faulty board if anyone is interested in it maybe to find the problem I would be happy to send it if they covered the postage and if they did fix it let me know what did.
Many thanks

Hi B/I,
With all that useful advice from Quuq folks, thought you would happily post carbonised remains free to a prospective masochist - after all, we suffer daily enough, already - Chris.
