I hadn't used my Computrainer in a few weeks and the unit died while I was prepping to get on the bike. An electronic technician said that I had "soft blown" the fuse in the power supply and it was replaced.

The unit now turns on but I cannot calibrate the Computrainer or control the unit either in ERG mode or through PerfPro. I keep getting an error of 99.99 when I try to to do the roll down calibration.

I have looked at a few different forums and some individuals suggest the problem is the DIN cable while others have suggested that there is a problem with the load generator.

Does anyone have any ideas, insights or suggestions?

Don't really want to buy a new trainer if I don't have to!

Thanks in advance.
