    Samsung Plasma PS43F4500AW Won't Start (flashing standby)

    Hi ... Samsung Plasma PS43F4500AW ... when powered with 240V mains standby flashes, pressing PWR button causes standby LED to go out but nothing further happens.

    I have already removed and benched the SMPS, jumpered PS_ON to GND, VS_ON to 5.3v and have VS & VA voltages and all other voltages available at CN4007.

    VS=213v
    VA=58v
    SVT_VS=213v

    This suggests to me that the SMPS is probably ok but I have no experience of TV repair so could do with some help.

    I have removed the XY-Drive board and checked all the ribbon cable connectors for shorts and found none, so I think the Logic+Mainboard is probably the fault but not sure how to proceed from here.

    What further tests can I do to confirm that it is the L+M board?, can I safely turn the screen on to test it? At the moment the SMPS is sitting with all other boards unplugged including the X-buffer (which is part of the SMPS in this model).

    Any help well appreciated ...

              Samsung plasma - flashing standby light
              by 7ony
              The 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.

              No visible...

              Samsung UE43KU6400U Flashing Red Standby Light
              by Bloopeta
              Have 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...

              Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
              by tvguy12012012120
              This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

              Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

              Samsung 60" Plasma TV, Blinking Standby LED
              by rju
              A sports bar/restaurant with ~40 Samsung Plasma TVs. This is the 2nd TV that has a blinking standby LED. I'd like to learn how to repair these TVs because I'd guess that over time more and more of them will develop this symptom. My hope is to repair the bad PCB, however if that's not realistic then I'd replace the bad PCB.

              Model PN60F5300AF, Type PN60F5300, Model Code PN60F5300AFXZA

              Upon applying power, the red standby is steady. When I tap the power button, the standby LED immediately blinks twice, then it blinks once ~ every 4 secs. Also, Upon applying power, the...
