    Vizio P552ui-B2 Backlight Diodes

    Have a Vizio P552ui-B2 that is starting loose backlight diodes. While I know I can get a hold of used strips, I would rather replace the diodes directly instead of used strips that will likely also start to fall quickly requiring me to tear the TV apart repeatedly to repair it.

    With that being said, does anyone know what voltage and diode package are on the strip for said TV? The strip model number is WT-EL-55UHD-A-V3. Again, I also don't want tear the TV apart in and attempt to see if I can find out this info.

    Any help would be greatly appreciated.

      I am not sure I follow. Do you mean buy new strips or diodes?

      Wish I could find new strips as I would get them, but this TV was purchased in 2014/15 and I can't find new parts for it anymore. That's why I was asking about the diode voltage and package type so I can just order enough to replace every single diode while I have it open.

      I don't mind taking it apart but also don't want to repeatedly if I can avoid it.

          There's a lot of LEDs to swap. https://www.ebay.co.uk/itm/223924920427

              I appreciate that. It's strange that this seller is in the US, yet the item for sale is listed only on the UK Ebay site.

                Thank you. I have come across that in my searches. However, "Please Read Before Purchasing:TvPartsGuy.com is a Tech to Tech sales company. We strive to help the Tech community find hard to get TV Parts at an affordable price. Registered Techs and Service Centers receive a 90 Day Warranty on all orders & No Restock Fee on Store Credit Returns."

                Thus, I could get a set and have one of the LEDs burn out quickly and be back in the same boat I am in. That is why I am trying to find the specs on the individual LEDs (package, voltage, color temp). If I can get those without opening the TV I can order enough to replace every single one after I open it up. ShopJimmy has some good videos about this and I have the equipment to do it.

                  I wouldn’t waste so much time worrying about leds burning out again. Usually the processor on the main board fail on this TV. Most likely that will go bad before leds so again

                    The leds can burn out one right after the other, which makes sense since they are all the same age, do you really want to be tearing it down every week, I would get a whole set, from a trusted seller on ebay or aliexpress, replace and turn the backlights down as far as tolerable AND get yourself a fan blowing on that processor, it should last a lot longer than without one.

                      Vizio M65Q7-H1 Red Vertical Strips fixed by tape blocking LC1 signal to half of the panel

                      Failure Symptom



                      No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.

                      Where is the short?

                      Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.

                      What Zener Diodes on a Linear Power Supply
                      by caspian
                      Dear members,

                      I have a linear variable power supply with unknown brand name that I used for voltage injection.
                      Then it failed. I discovered that its transistors (Q1 and Q2) are shorted.
                      In addition, I discovered that its zener diodes are defective.
                      I can replace the burned transistors.
                      But I do not know the model of the zener diodes. the model number is not marked on the zener diodes.
                      Therefore, I cannot replace the zener diodes.
                      I do not want to test the zener diodes in a test circuit to discover their model or value.
                      no schematics are available...

                      LED problem on samsung UE55F6475, 2 strips work. The rest is flashing every second.
                      by Kingfreddie
                      Ok.. this is the story:
                      Have an old Samsung LED 3D TV (UE55F6475). First it started to lose light on the lower 40% of the screen now and then. Like for 10-60 mins and then it would work again. Then a bit later it just got stuck in that position. The lower 40% of the screen is dark, and it gets progressively darker the lower u go so it's obviously that LED strips where not working. I also looked for similar errors online and saw an exact copy and on that one it was faulty LED strips.

                      This is kinda how it looked, just that mine were at the bottom of the screen:

                      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,

                      I have a Samsung TV, Model UN40f5500afxza with burnt out LEDs & Diodes.

                      Strip Model numbers

                      My problem is I don't know what two diodes to get for the strips, in a good video it was stated they where TVS package SOD323. The Diodes are marked 4E BA, and 2 BA. I have looked up SMD code with no luck. If anyone could please let me know what part numbers or specs for the 12v and 24v marked diodes...
