50 Error

Power off for 20 minutes to allow the capacitor on the DC controller to fully discharge. If you don’t allow this capacitor to discharge, you will still get a Error 50 even if you have fixed the problem. This may clear the error – either temporarily or permanently. If it clears the error it was most likely caused by a low power problem i.e. low line voltage causing the power supply circuits to drop out of regulation. Low/unstable power (low line voltage, brownout condition). If it doesn’t clear the error you may have one of the problems listed below.
