Question about Heating & Cooling
I had this problem, no power, no light. It was the power supply output fuse. It appears to not be blown, but a continuity check across the fuse shows an open. Unsolder and replace the 5A, 250V fuse with some locally available Radio Shack parts (holder - 270-739, fuse 270-1071). Access to the power supply board is on the rear, remove the screws on the plastic plate, including the one hidden under the QC sticker. While you are in there, clean the fan and the aluminium fins on the heat sink (cools the Peltier device).
If your fuses are not blown, look at the electrolytic capacitors (the black or blue round metal cans with the aluminium X on the top) to see if they are bulging. Replace any that are bad (a common problem in switching power supplies).
Hope this helps,
