thanks for message, i've been there but cant find the info i require. i need to find a full layout pic of the motherboard with the fuses shown and identified, or even any of that nfo via several sites. i get an error message 'insert controller into port 1' and am assuming it is a fuse -UNLESS you know different and can help

thanks

All the on board fuses are located together in a small cluster, they are small black cubes about 4-5mm across and on older models located very close to either the power supply connection or the laser connection.

Take a look at www.paulmax.eng.net for a pic of the fuses for a PU-8 motherboard, I know its not the right one but it should be enough to get it sussed.

Sorry its not in time for X-mas
