    LG 42PC3D red LED blinks green 3 times

    So my next project I have is this 42" plasma that has a few posts on here, specifically this one that has the same blinking led issue. However I'm not sure if it was power surge as I was given this by someone. Opening it up it looks like someone tried to mess with the power board as a capacitor was missing. I have a replacement board installed and am getting the blinking with this "new" board.
    I tested the 5V coming from the power board to each the YSUS and ZSUS boards and it is only .8.
    I did notice that the small control board does not have a blinking green LED as I've normally seen on the plasma's. Is this maybe my first place to start?

      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
      by Tynan Dill
      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

      Upon bringing it home and plugging it up, it showed a standby light.

      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

      The screen seems to blackout and stay black, but with a flashlight I can see the display.

      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

      Assuming...

      HP Pavilion 15-eh Board DAG7HAMB8F0 - CPU throttling to 0.4GHz (PROCHOT_EXT) and black screen
      by m1ch43lzm
      Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
      Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

      TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
      by howardc64
      All left and right refers to looking from rear of TV (or looking from front with TV upside down)
      • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
      • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

      Sony KDL-40Z4500 LCD with stripes and 9 blinks (possible BGC board or harness problem
      by huj3r
      Hi there!

      I have a Sony Bravia KDL-40Z4500 which shows a colored vertical stripes pattern when turning on, with a central black shadow that slowly dissipates within the first 10 seconds.

      Photo of the situation after the black shadow dissipates:

      After this behavior the red LED will blink 9 times, then pause for a bit, and blink again 9 times, in a loop.

      I checked the manual (available here) and this corresponds to "HFR error", quoting from the manual:

      > This indicates HFR Communication error. [ HFR Communication...
