This unit had flashing power led.I checked the standby voltages and on dm854c and 854c i had same pulsing voltage of 13 volts but would disappear and return with standby led. Further checks of mosfets found nothing but check of d9001c and d9002c found voltage was dropping suddenly.D9002c was shorted.Replaced it with a MUR460 and unit is back on road.Power supply is a BN44-00807A.
