This is a bad power supply and an easy fix. Their are several electrolytic capacitors on the power supply. If one is bad it will have a bulge on the top. Mine had a bad 2200uF and a bad 1200uF capacitor. About $7 worth of parts at Radio Shack. Radio Shack had the 2200uF but it was axial leads instead of radial. (leads come out of each end instead of one end) but It will still fit. They only had a 1000uf capacitor so I combined that with a 220uF capacitor and wired them in parallel. Make sure you put them in with the correct polarity.

An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.
I have the 26MF231D and it worked great afterward (even though you can't mount it)
Here is how you remove the cover.

Had the same issue, I replaced two 1200uf caps on the power supply board and now it works fine again. Remember to replace the caps with caps rated for at least 35wvdc.
