    Philips 42PF5520D/10 plasma screen flashing when turned off

    I replaced two 3300uF 10V caps with Panasonic FR's (and tested the rest) on this Philips TV with Samsung internals about six months ago, it was used for couple of days to test it, and then it was forgotten in storage untill this week.
    Three days ago I brought it back to use from the storage room. First day it worked perfectly.
    After the second day of use this problem appeared.
    The plasma screen will start flashing like this as soon as you plug the TV in. When turned on it works perfectly and the image is perfect. After turning off it will continue flashing.

    The video explains best: https://www.dropbox.com/s/re5nqtw1al...4_Pro.mp4?dl=0
    At 0:24 I turned the TV on, and at 0:52 I turned it off. The flickering when the TV is turned on is just from the camera.
    As you can see the sound comes on few seconds before the picture

    Has anyone seen anything like this before? What could cause something like this?
    I find it strange that this starts immediately after plugging it in... I haven't had the time to open it up yet, but when I do I will post pics of the boards.

    Any ideas before I open it up? It's so damn heavy and has a milloin screws so I haven't started the repair yet. (and it's only my kitchen tv so not in a hurry)

      Elitebooks (820, 840 etc. all gens) and those continuously flashing Power LED + flashing CapsLock LED
      by STKR123
      As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
      I wonder if re-flashing the BIOS might be of any use here.

      As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.

      There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,...

      Philips Pus 436401/12 flashing backlights question
      by KevM
      hi had loads of help from this forum getting TVs back up and running but seem to be hitting a brick wall with this one.
      Backlights failed before Xmas so ordered a new set and after replacing them and putting the set back together was delighted to see it work for 15 seconds only for the picture to flash on and off and a quick look round the back confirmed the backlights were flashing on and off

      I have a steady 44v at +vled and a fluctuating 0v to 10v at -vled when the light start flashing, a steady Bl-on voltage and steady dim voltage.
      If i disconnect 2 strings of leds...

      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...
