    TV backlight zener diode

    Hello everyone, I'm repairing an LG TV backlight and I noticed some strange behavior when I touching the backlight strip with a missing Zener diode.

    So I replaced the leds on the strips and they seemingly working fine, but soon as I touch the strip which has a missing Zener diode the whole backlight turns off for a few seconds and then turns back on.

    Is this caused by the missing diode? If so what kind of zener diode should I use to replace it?.
    ​​​​
    The led strips has 9 6V leds.

      NTE Electronics “NTE5251K” Zener Diode 9.1V @ 50W Do-5.5% Want to build a 9.1 output from a 9.6 lipo4 battery pack
      by sam_sam_sam
      I have bought this Zener Diode for this project what size and wattage resistor value do I need to use to get near 50 watt output
      I bought this from an eBay seller but unfortunately they only had one

      I bought three from Vetco Electronics these are Sylvania ECG5185A 9.1@10w A to Stud what size and watt resistor do I need to use to get near 10 watt output
      I bought three of from them to also make battery packs with this output power limit in mind

      I want to use this battery pack and turn it into a 9.1 output battery pack output to eliminate using 9 volt battery...

      What zener diode might fix the sound on Maestro Mayhem gaming chair?
      by nev1001
      Hi, I'm looking for a bit of help trying to fix the audio unit from a Maestro Mayhem 4.1 gaming chair please.

      The chair has a few speakers and vibration motors. All was well, for a while, but now the sound is gone.

      It may be significant that I discovered my son was powering it with a 19V laptop charger when it should run on 12V - it did fully work, for bit.

      I think an issue could be a zener diode (or capacitor) which has shorted out.

      The board's bluetooth input still works, the vibration motors are working, so is the line out socket but not the...

      Corsair RM1000e - Help identify 5VSB Zener diode
      by hobostove
      Hey there guys. I've got a Corsair power supply that's come across my bench dead. I usually don't mess with power supplies, but it's a slow week so I'm giving it a whirl.

      Taking it apart I heard a screw rattling around inside, and when I got it apart I found a couple blown components near what I think is the 5VSB area.

      There's a 22ohm resistor that's melted and open, but it still has the bands.

      The other part is a zener diode and it's top went to jesus, so I can't read the marking.

      It looks like the diode connects the source and drain of a TNY284...

      Missing LCD Panel Voltages VGH, VGL, VCOM (TCL 55P6US Sound & Backlight but NO Picture)
      by maneatingmonkey
      I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.

      There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.

      UN65TU700DF picture and sound but no backlight. BL tests ok but repl. PSU didnt fix!
      by triplefour
      this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
      i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
      unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
      according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...
