    Lg 60pz 550-ua

    Looks like the plasma LG 60PZ 550-UA parts are all out of stock. Ours started the strange color issues then progressed to the black jagged edges and very dim picture.

    I checked the ZSUS board and saw the cracked solders for the coils as others have seen. I repaired solder and now almost total black screen with normal sound. There is buzzing noise coming from ZSUS board. All fuses check OK.

    Should I just replace the ZSUS board and the main board or forget it because parts are very hard to find? Only found one ZSUS board out there;

    #EAX62076601 for $114.00 in San Antonio Texas.

    I find it hard to believe these LG's are this bad. We bought ours in 2011 new. Thanks for any input.

    Sounds like the arcing on the ERC coil dry-joints caused something else to be damaged.

    Worth checking the IGBT's on that board....

    It aint just LG sets that are popping off at 3 years old--Panasonic are just/if not worse as that.
    --Nothing much post 2011 has much in the way of quality anymore....

    LED type sets are even worse,--but their issues are often Unrepairable panel problems!

    For reliability--Go for something Pre 2009!

      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

      A1312 (27” iMac 2009-2011) A1407 (Thunderbolt Display) A1316 (Cinema Display) Display Black Screen Repair

      Problem

      This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

      LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
      by Hakuu
      Hi There,

      This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

      After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

      More Details
