thanks scott i pulled the board out and there was some foam padding glued to the bottom of the board on the printed side and i guess this is to stop vibration i pulled it off and removed the glue as it had crystalized and with some thiners i wiped it all off and replaced the board and the mig works a treat and has worked for hours today on a project so i recon the glue must if conducted this happens in some satelite reciever psu.s the relays in these do look naff though hope this helps someone else
