    Re: LG 26LG3000 white screen problem

    Thanks. Will try and find one from some junk boards.

    There's still the low voltage on t-con main rail problem, probably gonna need the AO4449 mosfet replaced.

      Hi
      Im having a similar problem, white screen of death.

      I have measured the voltages to the T Con and they seem correct.

      I have taken resistance measurements with respect to ground:

      VDD = 34.7
      VDA = 2.39K
      VGHP = 1.4M falling
      VGH = 600K rising
      DP1 = measured ok using multimeter diode test function
      DP3 = 39.4 one side and 0 ohms the other
      CP42= 34.9
      CP35 = 34.9
      CP36 = 34.9

      I am suspecting it may be DP3 but do not want to jump to conclusions without consulting the experts first.

      Any help on this matter would be much appreciated.

        Plug power and signal to your monitor and measure some voltages on the tcon, at the points where you measured resistance.

        A working TV? How boring!

          Viewsonic VS16217 strange problem - white flickering screen on power up
          by domu
          As per subject, on power up display shows no image, but white
          flickering screen. Strangely, it only happen after power was lost
          when it was on. After power returns - white screen only, but if
          disconnect power for 12-24 hrs, and connect then again monitor
          works normally.

          Any clues how to go about it would be greatly appreciated.

          problem with replacing lcd screen
          by mmccomputer
          I have an HP model : 14-cf0011nf and I want to change its display screen (it has an original 14" full HD TN 30 pins panel) which works without problem but I want to put another screen with an IPS panel, the problem is that I tried several screens but there is no display except with the original screen, I never had this problem before I changed hundreds without problems but this PC is not 'accepted than its original screen
          otherwise on the motherboard it displays edp and I don't know, do the panels I tried only work with the LVDS protocol?
          If anyone has any information on the subject...

          LG 55EC930V OLED - swich on swich of no screen
          by maxim2511
          My Oled Tv is 55inch tv, 3 days ago I notice that middle of the screen is getting warmer and on picture I have ghosting, missing red color. Color red was still displaying, but it was not so strong as corners of the screen and watching some movies makes me angry.
          Then I get an idea to take it apart and clean boards from dust.
          In side of Tv was not so bad, I take compressed air in can, and gently blow up.

          Also I was thinking to styrofoam sponge to isolate power board from screen that the middle of the screen will not worm so much. Because Led on screen when gets higher...

          LCD TV Green/Pink screen problem
          by jimjoe123
          I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.

          Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.

          Then each time...
