    samsung plasma problem.

    HI I wonder if anybody could help with some advice please, I have a ps43f4500, when I plug the power in the screen flashes and then goes off, if I do get the tv on it stays one for around 30 seconds and goes off.
    When that happens the power led gives an intermittent blinking.

    When it stays on, is picture OK, without any lines or distortions?

      No distortions at all, got as far as going in to the menu.
      VOltages all test present and correct they go to the levels they should and then start to decrease.

        OK, on the control board/logic board (in the middle of the TV usually above the stand) there is an LED. It should blink, when running about once every second. When it stops, does the blinking change? Does it stop blinking, or start blinking slowly?

            Slow blinking indicates control board has detected a fault and has stopped the panel operation. Faults vary, Samsung don't indicate what triggers it (annoying to say the least.)

            It would be ideal if you have two multimeters to check Vscan/Ve and Vs/Va independently - see if one cuts out before the others for example.

            If you don't have two meters you can try heating/cooling things to see if you can get the problem to occur quicker, a hair dryer works well.

              Problem with LG Plasma 60PM6700 - Random power downs
              by theone111
              I have an LG Plasma TV 60PM6700 for the past ~12 years.

              In the last ~3-4 months I have been having some issues.
              1. Problem: It started with random picture disappearing (sound still worked).
                Frequency: Happened about once a week.
                Solution: Had to turn off TV wait a few seconds before turning it on again.
              2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                Frequency: Happened about once a week.
                Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
              3. Problem: TV shuts down

              Samsung UN55JU650DF network/streaming problem
              by howardc64
              Fixed a 9 year old UN55JU650 by replacing backlight. Original backlight LED was still working after 27k! hours but terrible picture of course. Few LEDs were out, 5-6 lens fell off (bright white spots) and another few popped off with slightest force. Surviving LEDs were all slightly blue so picture has a blue tint.

              This TV runs older Tizen OS (updated to latest version, see pic) and have problems with network (wifi or ethernet) connection. The Tizen UI frequently switch to coax input source while changing content sources. . If no good signal (coax not connected, no prior antenna/cable...

              Samsung PN50C540G3FXZA 50" Plasma, power cycling, Y-Main problem, Canada
              by bcstedt
              Just starting to crack into this one and wanted to get the ball rolling.

              At power on (plug in), power light on, relays click, repeat (sometimes)

              After disconnecting Y-Main from SMPS power stays on and boot up jingle is heard from speakers

              Removed Y-Main for inspection and testing
