    Sceptre X505BV-FMDR - Found Bad LED

    Been trying to fix this TV for some time. I tried a replacement power supply and main board but I still had power to the tv (the blue led bulb lit), sound, but no picture.

    I finally opened it up to test the LED strips. I did this with my multimeter and popping off the lenses to test them (I've since realized this wasn't a great idea) I found a single LED bulb out and perhaps 1 that was dim.

    Would a single failed LED cause the entire backlight to not work?

    I did receive advice that I could "short circuit" an LED and just move that strip to the bottom and it would be barely noticeable. I'm not sure how to go about this.

    Does anybody happen to have any LEDS for this TV? DLED50SJ5X14 0001.A-1

      Yes a single LED can cause the entire backlight to not work.
      The LED will be either 3v or 6v and is identified by it's dimensions.
      Also note the correct anode and cathode position.

          Thanks for the reply. I guess I'll need to track down an led strip for it. At first glance I see 1 on ebay for $30 unless I can figure out to short that defective one out.

              TOSHIBA DLP 52HM95 How to reset timer module on bulb
              by repair-it
              I replaced the bulb only on my Toshiba DLP The bulb is a TB-25. This is the first time I've done a bulb only replacement. Supposedly there is a timer module that needs to be re-calibrated or reset. I don't know where the module is located. I see some vendors selling the bulb with the housing stating module included which leads me to think the module is located inside the enclosure the bulb mounts in, but I didn't see it. Maybe it's inside the plug attached to the bulb?

              Anyway - I am seeking information on how to reset this so called module so that the lamp will operate. Apparently...

              LUMIMAN Smart Bulb IC ID?
              by ezenia
              Hi,

              I have a LUMIMAN Smart Bulb that suddenly stopped lighting one day. The bulb is still detected in the app, but won't light. I've probed around and nothing seems to look off with any of the diodes, caps or resistors. The Bluetooth/Wi-Fi module seems to be working as it's still detected in the app. I even tried deleting and re-pairing the bulb (it didn't light, but I was still able to follow the pairing instructions), it re-paired fine, but still no light.

              In diode mode, the LEDs all light up when probed so I'm guessing this means the LEDs themselves are OK. I was expecting...

              Hofmann geodyna 6300 Wheel balancer
              by Grouickman
              Hi there,

              First, I'm not sure it's the right section to post for this type of device, but could not think of something better.

              Ok, so my son (a mechanic) bought a faulty Hofmann Geodyna 6300 wheel balancer (which appears to be mostly a re-branded Snap-on wheel balancer).

              I'm looking for any resources (doc, manuals, schematics) that would be available for this device or anyone that would have any knowledge on this particular device (or its Snap-On equivalent).

              I'm trying to diagnose the fault(s ?), but I can't find any schematic (appart from the...

              Huawei D15 no power found corrosion damage
              by B2L_Repairs
              I got a huawei D15 that came in for no power repair. Device charges , charging led flashedms but doesn't turn on. I found corrosion on an IC (ic name is BDJCY1...I can't find out much info about it online). I removed this ic and two pads are corroded but they can be repaired. To my knowledge inductors never short to ground (i might be wrong and please those that are more knowledgeable than me can correct me). I found few inductors short to ground when my multimeter is in beep mode ,indicating a short in the line of those inductors...but I don't know how to go about to find the shorted component...

              Macintosh Quadra 840AV PSU
              by nicktasios
              I had my Quadra 840AV (which I recapped and had working) plugged in for some time without using it and randomly decided to turn it on today. Unfortunately it did not turn on. After checking the PSU, I found out I was not getting anything from 12V, only from the 5V rail. After a few minutes, I removed the PSU and plugged it back in the electrical outlet and it suddenly started making a weird sound and soon after smoke started coming out. I quickly unplugged it. I opened it up but on first instance I didn't see anything out of the ordinary really. I later turned it back on and one of the MOVs blew...
