    LG 50pm6700 with shorted upper buffer board

    I have a 50PM6700 that has a shorted upper buffer board so I removed the board and tested the tv. As you can see it has two transparent grey bands on the bottom half. Is this another problem or just due to the upper board being removed ?

      It's likely your lower buffer to panel connections are not seated properly. or it could be a bad lower buffer also

          Yep....Turned the TV back on now no lower picture at all and the Ysus voltages were jumping around like crazy. Disconnected the lower buffer too and now my ysus voltages are back good and stable. Looks like I'm on the hunt for buffer boards.

              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....

              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...

              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...

              HP Victus 15-FA1025NL , board DAG3PAMB8D0 REV:D, shorted CPU DrMOS and n-mos
              by modtool
              Hi to all,
              the owner of this machine gave it to me after having opened it to take off the dust from the inside, telling me that after that it didn't start anymore.
              I found that one of the DrMOS (AOZ5016QI) on the CPUCORE was shorted between VIN and VSWH, and that one of the two n-mos connected to the power jack was shorted aswell.
              I unsoldered the two shorted components and verified that there were no other short circuits, then decided to power the mainboard, firstly with the lab power supply, then with its original HP 200w charger, but the behaviour is the same, the board starts...

              Panasonic TC-P50S1 shorted TXNSC1EDUU (TNPA4782AB) SC Board
              by Yanleb
              Hi every one. I just want to share the successful repair of my shorted Panasonic TNPA4782AB SC board.

              I don't usually do it but so many parts were shorted that I decided to buy the ShopJimmy repair kit instead of sourcing each components individually. Here is the list of components the kit contained, with a remark indicating if I needed that part or not :

              D608, good
              D618 RF101L4S, good (See warning 1 below)
              D619 RF101L4S, good (See warning 1 below)
              D865 RF101L4S, shorted (See warning 1 below)
