    Looking for a zener diode for a Magnavox 37" Lcd

    Hey guys - found this site with a google search, and looks great.

    My problem - I've got a Magnavox 37" LCD with a bad cap and a bad diode. I've narrowed the phillips part number down to this:

    933117780133

    This is a 9.1v zener diode, I believe.

    My question is what is the equivalent part I can get from Radio Shack? I'm having a hard time locating it on the web.

    If anyone has any advice, please let me know. This will be my first attempt at a repair, and hopefully it goes well.

    TIA - Adam

      I entered your part # at digikey.com and it shows as a 9.1V 1/2W zener diode made by NXP (now owned by Phillips).


      http://search.digikey.com/scripts/Dk...=568-5809-1-ND

      45 cents each and they "only" have around 20,000 in stock. Buy a few of them just in case something else caused it to fail. Use the USPS First Class shipping option for the lowest cost shipping.

                  Just wanted to let all know that I successfully repaired the tv - I ended up replacing four caps on the power supply as well as the diode. The diode had burned the board, but still had just enough copper to make the connection.

                  Thanks for your help, and for saving a nice tv from the landfill!

                      TV backlight zener diode
                      by unimatrix93
                      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...

                      Element 32 inches tv (ELEFW328B) Unknown component: Diode or zener?
                      by Vincenzo2
                      My Element 32 inches tv (ELEFW328B) lost it's backlight (confirmed with a flashlight test) and the connector on the PCB (it has one board that has a processor chip, switch mode power supply, and backlight circuit) that has the two wires that go to the backlight LED strips has a very low voltage (28-29 volts) when turned ON, in my opinion.

                      Started testing components and found an SMD diode or zener that is shorted (even zero fusing resistors read a few tens of milliohms, while this thing reads zero).

                      I put some pictures here to show that it is labeled "M7"....

                      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...
