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.
Have tried removing panel ribbon cables one at a time, and that makes no change.
With mainboard unplugged, all voltages from powerboard seem ok, but with mainboard connected, they never quite reach full voltage, and drop and raise in a constant loop (in time with click noise from mainboard.
Using backlight tester, I get 63.6v on both sides, so seems like no bulbs... -

I aquired a Samsung UE46EH5000 from a lady that said it was turning on and off so she just purchased a new one.
On plugging into the mains and turning on i get a solid red light.
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... -
by 7onyThe TV is a 2013 Samsung plasma, model # PN60F5300AFXZA.
Snagged it up in non-working condition a couple years ago. Previous owner said that sometimes he could get it to come on after repeated tries but other than that he couldn't get it to turn on.
Personally I haven't been able to get it to turn on at all. The standby light comes on solid when plugged in, but pressing the power button results in the standby light flashing once every 4 or so seconds. No "click" noises, no light from the panel at all. Just the flashing standby light.
