Hello everyone, I have a Mitsu WT-43211 that fails to turn on. Has the typical fault that I have read on the posts. When the power is selected on, the green led flashes and a click is heard and it fails to turn on. Holding the menu and input shows the 2 pause 2 fault code. I have removed the back cover and getting ready to start T/S. Im looking at any that might be an easy fix, loose connector, loose solder joints etc... My first question, when i pull the light box, is it ok to lay the box on its side? While I inspect the solder joints. Im afraid it may leak coolant as I have heard that it will happen.
