    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.

              Display problem on a Samsung U28E590D
              by Neptune06
              Hello,

              I have a display problem (bad size and color) on a Samsung U28E590D and i'm wondering if someone have access to the service manual for this monitor. I used a faulty Lenovo thunderbolt hub connected to it and now i suspect a problem on the HDMI part of this monitor. The main PCB board part number is: BN94-10748G.

              Thanks for your help.

              Samsung QE50Q67T bootloop problem
              by Roccolade
              Hey everyone.

              I have a Samsung QE50Q67TAUXXC (same as Q60T i think) which is experiencing constant bootloop. The picture comes on at first but then it begins to reboot again and again. I tried taping off the pins one by one on the ribbon-cable connecting the two panels at the bottom - and found that the bootloop stops when 1st pin from the left is taped off and the same if the 46th is taped off. (See picture). But unfortunately, I get no image on the screen in those cases.
              The bootloop also stops when the whole right side is disconnected. Which makes me believe the problem...

              Samsung UE32D4010 Backlight problem, led ok
              by fanaticgames
              hello I have a backlight problem on this TV, if I unplug the cn201 cable the backlight works perfectly and the voltages are 13v if I connect the cn201 cable the backlight goes off and the voltage drops to 12v, I assume it's a motherboard problem, the question is has anyone had a similar problem? I want to understand if the motherboard is repairable or it's not worth wasting time...

              Samsung QN75Q70TAF - Problem ON or WITHIN the Display??
              by KYBOSH
              Came across a 75" QLED TV with restart-backlight no boot and it was headed to the dumpster. Asked the owner to let me have a crack at it. They said the TV went out during or soon after a thunderstorm. I noted this but didnt out too much stock into it as it could have been anything.

              VERY big TV and i was worried about the display cracking during the moved as well as the repair but it was alright as i try very hard to handle with care.

              In the video (zip file) you can see' as the TV tries to start up, tbere are a lot of gaps in the backlight so I immediately suspect...

              panasonic TH-42PC77U plasma television half screen problem
              by renech
              hello,
              I hope someone on this forum can assist me.
              I have a panasonic TH-42PC77U plasma television.
              the lower 1/2 of the screen has become flaky....in and out, then finally goes black and you can only see the top portion.
              i have performed the reset to default settings quite a few times. Panasonic recommended..did not believe this would help...it didn't.
              I have removed the back panel and looked around for something obvious...burn marks in a board, etc....nothing obvious...
              I have read some posts that suggest the problem is related to the boards on the left...
