What sort of machine is it? Refrigerated, Ducted, Gas? To do a full reset correctly, you must switch off at the main isolator next to the unit or at the meter box and leave it off for at least 15 minutes. A quick on / off does not reset it properly. If the unit is a refrigerated split system , and the outdoor is running but the machine is not blowing cold outside and hot inside (On heating mode) It could be due to a gas leak / shortage.

Disassemble fuser unit and inspect thermistor and thermostat for dirt or damges, and heater lamp for damages.

Good luck.

start windows in vga mode by pressing F8 at starting after POST. then set the resolution of your screen to 800X600 and restart.

you might have a loose connection within the device if you take the battery out their is only a couple screws holding it together i would check all connection are ok

define your question better please, it is possible for the FCU on this model to hang, requiring a FCU memory reset through the sp mode.
