Just having major problems with my 24TT. I switched it on and heard like a fuse going. Epliog reckoned the mother board gone. Couldn't see anything wrong. On further investigation I noticed a capacitor blown on the combo board in the front of the machine. This connects power supply to mother board,x y axis motor and display panel. Bought new combo board no change. Mother board was getting 48 volts but not lower voltages. Suspect the power supply unit fitted on top of main 48volt unit. On removal I found a fuse blown. Replaced fuse and it blew straight away. Disconnected all outputs from supply and still blew fuse. Power supply definitely iffy. Any suggestions. Notice a thermistor looks a bit damaged see black component on photo. This power supply is no longer made by PowDec.
