Press and hold switches in the following order:
MIXER KNOBS
RESET CONTROLS
ENTER and 5
to diagnose FAN, RAM ( no need to open the case if components were sitted properly at first place) and other things.
Regarding power source:
Remember that UPS topologies have unprotected paths that may expose the Kronos power supply to transient overvoltage.
Surge Protection Device is a must,
and some clamping devices tend to exhibit leakage current at low voltages regardless. Quality of power supply plays as well a crucial role, especially in IT equipment. |

Start Kronos normally, default is SET LIST.
Use two hand, and
MIXER KNOBS (press and hold)
RESET CONTROLS (press and hold)
ENTER (press and hold)
5 (press and hold)
Release switches when a black screen appears with FULL DIAGNOSTICS.
Once it's done, turn Kronos off.
Your colours will be back with a next reboot. |

You are not necessary correct.
If you see on your display -> value 0 RPM 0, you are in a FAN CONTROL TEST MODE.
Use VALUE slider ( next to MASTER ) to change value from 0 to 128.
Your RPM should mirror your changes (e.g. in an ambient temperature of 15 deg C, when value =128, RPM = 2636 )
If you get those reading than it means you are OK.
Press ENTER to process to the next TEST. |

i was following this thread, and i want to know what happened to your Kronos finally?
Was it the power supply issue or something else? As i ve recently started to have the same 'power cycle' issue on my kronos.
My K2 is connected to a spike Guard and I'm contemplating to get hold of a UPS.
But is UPS the answer or is it something else?
Please do revert
thanks |
