I’m experiencing the same problem with my Time Factor, it’s like every knob is being turned and the display struggles to keep up with the changes. The ribbon cable is a good explanation. However, I can get it to work for a while with a factory reset, and I never change the factory settings. It works for a few days then the TF goes crazy. I have reverted from 5.2.0 to 3.5.0 and for 2 weeks so far it has not gone crazy. Coincidence? BTW this unit has never been gigged or moved out of the studio.
