    Samsung PN50A550 Plasma doesn't light up

    Please bare with me as I'm new to this Forums & posting thing.
    My TV will not get bright until its been on for hrs. Is this a common problem?
    I have replaced the power board once before because something fried on it. I am not afraid to tear it apart again, but have no clue what to look for or test!

      Re: Samsung PN50A550 Plasma doesn't light up

      I remember seeing these just after the 550b series came out (thinner and cheaper). These were a bit thicker first 1080p. They must have been good units since I never found any that were not working.

      I have no history with these and I would guess they are worth repairing as they were one of Samsung`s last effort at building a good plasma tv.

      Sorry I can`t help at this time.

      Pictures would be great.

          There is a common issue with the relay failing, which fails to remove the thermistor from the start up circuit. Hence it takes a long time before it will work. No idea if A550 is affected.

              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 QLED QE65Q7FNAT only standby light
              by Kaar3l
              TV: Samsung QLED QE65Q7FNAT
              PSU: BN4400940A
              MB: BN94-12832K

              I got the tv in spring 2024. At that time it started, then ran 60 sec and poweroff. Seemed like reboot issue. I didn't have time and room to check it in summer so I plugged it in and now the standby light is on. I press button on remote, standby light goes off and tries to start?. No picture or backlight on LCD. I thought about removing diodes like in this thread: https://www.badcaps.net/forum/troubl...sung-qled-q60r...

              Samsung UE60KS7000 No Standby Light
              by marcinq
              Hello,

              I've got a problem with a Samsung UE60KS7000 that was given to me and said that there was a problem with the One Connect box but as I understand the TV should turn on even with the One Connect box disconnected (which it doesn't). There is no stand by light.

              I've disconnected the Main Board from the PSU and when connecting to mains the backlight turns on which suggests the PSU might be ok. I've measured the voltages out of the PSU and they seem reasonable (like the labels say). The main board has no obvious burns, there are no shorts on the power rails anywhere....

              3) Backlights do not illuminate, voltages associated with backlights on Power Supply are not present
              4) "Power on" terminal on Power Supply has 3.26v
              5) "A13V" terminals have 12.9v
              6) Stand-by test jumper on Power Supply has 12.9V
