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.

by BloopetaHave a Samsung UE43KU6400U that will not turn on, just continuous flashing red standby light.
Power button does nothing
Have unplugged the mainboard, and backlights illuminate.

I aquired a Samsung UE46EH5000 from a lady that said it was turning on and off so she just purchased a new one.

On using the on/off button or remote i just get a flashing red light in a pattern of flash/flash gap flash/flash gap flash/flash etc.
Opened it up and disconnected the main board from the power board by removing the connecting ribbon cable with the hope of getting either a 'no backlight' or a 'working backlight' but got neither,i just got a blinking backlight that turned on and off randomly... -

Then the computer refuses to power on at all. Now only the caps lock button flashes 7 times then stops. The charging light is always on whenever a power source is connected (battery or charger).
I tried long pressing on the power button, after several seconds it would go off then when the button is released... - Loading...
