Have checked voltages according to the manual on pins and all seems to be ok. We have also changed over the bridge recifiers. I am thinking now there may be an issue with the +5v. Is it worth while changing that "black thing with the little silver thing in the middle" I have no idea what you call it, as that does seem cold when I fire the machine up.
See pic
the black thing is just a heat sink to disperse heat from the 5 volt regulator transistor (the silver thing in the middle).
did you said the voltages where ok? do you have 5 volts any where?
check the big blue thing below it (capicitor) i am not sure if that is the 5volt cap or the cap for the insert lamps.
the heat sink will only get warm after a while, they usually take a while to warm up depending on how much load is on the transistor.
also i notice that there are no fuses in that board pictured. without fuses it will not work.
check the manual for the correct value fuses
