IM414 stopped working, no power

When the power came back on there was a power surge. It needs professional service for either power supply or the mainboard.

When power goes off, you need to unplug all electronics and just leave a room light on to alert you when the power returns. Then go around and plug all the electronics back in.

the system has run for 750 hours and you have to clean the filter

I would guess power button is stuck on. It can be replaced.

did the voltage selector on the back of the unit possibly get moved to wrong setting? You could also try switching it back & forth a few times (unplugged first of course) to see if maybe the switch needs "cleaning"

Assuming that the unit was working fine before you cleaned it. Did you remove the back lower panel while cleaning it? It the panel that holds the electrical socket and fuse. If you did, check to see if the electrical connector is seated to the main board. Also check if the keyboard connector (the one that looks like a telephone jack) is plugged into the main board. Also, check if you model has a switch on the back that it is set to the on position. And press the power switch on the front keypad to see if that make the unit work. That all I can think that might have gone wrong.

I got same issue. Solution is to buy a efergy standby eliminator plug so it can respond to the On/Off signal by cutting off and restoring mains power

The auto defrost heat element is not working. When the ice buildup clogs the airflow the unit stops cooling. Once you unplug it and give it a chance to melt it works again. You need to have the defrost unit replaced.

HI. if this unit isn't powering up, it could be an issue with the power supply board. To confirm this diagnosis, i would unplug this unit from the surge protector for about 5 minutes. once the 5 minutes are up, plug the unit into a regular wall socket. If the unit doesn't power back up after being unplugged for 5 minutes, this will confirm the power supply failure. you can order another power supply board form the manufacture or, you can simply send the unit back to Sony for this repair as well. If this unit is not plugged into a surge protector, it may have received a surge of some sort.

Please rate and god bless:)

The contact where the Zune plugs in was loose.
