Thanks Beaky, how do I test that capacitor?
Also, is there anyone that I can send these boards to or someone willing to come and look at them?
sorry i made a mistake before with the big blue cap, that would be before the 5 volt regulator and it should have between 9v and 13v dc.
check this with you multimeter on set on dc.
there should be some pins marked TP1, TP2, TP3, and so on, with your multimeter set on DC and the black wire (-) hooked to a braded ground wire or to one of the screws holding the power supply board to the back box touch the red wire (+) on to each of these test points and write down what voltages are on each of the test points. when you have done that post those voltages here and i should be able to tell you if your 5 volts is present.
as far as the capacitors go if they are the original ones then they probably will need to be changed.
if you want you can send the power supply board up to me and i will be able to rebuild it for you, (ie change all the caps + bridge rectifiers and make sure it is working properly)
it would be a bit hard for me to test the other boards as i don't have a schematic or a zaccaria pin to test them in but if worst comes to worst and you can pay for a cheap return air fair for me i would be happy to come down and sort it all out for you if no one else locally can do it.
