                          by howardc64
                          2+ year old TV with many (720? 65" version has 720) mini LED dimming zones. TV boots, has sound, panel picture can be seen with flashlight. No backlight. No TV model sticker on rear panel (Maybe Samsung service removed it, read below). Found the model # through the PSU and zoned LED driver board numbers.

                          PSU has a click near LED output circuit at 1 second interval, sounded like the 4x barrier rectifier area. Protective pastic liner under PSU shows heat signature on the Schottky Barrier Rectifier in this circuit. Found a shorted diode (2 diode per rectifier, failed rectifier labled...

                          Definitive BP7006 Plate Amp – Powers On, No Sub Output (Need Help Diagnosing)
                          by SteveCHS
                          Hi all — I’m trying to diagnose the plate amplifier from a Definitive Technology BP7006 tower.

                          Symptoms:
                          - The amp powers on (red light illuminated)
                          - No subwoofer output
                          - Main towers still play normally through my receiver
                          - No audible hum or noise from the sub section

                          What I’ve done so far:
                          - Verified fuse continuity
                          - Visual inspection: no burned parts
                          - Confirmed speaker driver reads ~5Ω DCR
                          - Board ID: LT-C126 (stamped on the PCB)
                          - Cap glue confirmed factory adhesive, not leakage
                          - Using a UNI-T...

                          MBR3045CT and SR3045LCT Schottky diode testing help.
                          by Baste
                          Hello experts,
                          Can anyone educate me on how to test MBR3045CT and SR3045LCT Schottky diodes? I'm totally a newbie in electronics, so forgive me if I have cheap tools. In my effort to repair a Gigabyte PSU, I stumbled upon the two diodes, which I suspect are leaky. I tested this with my two cheap multimeters and the newly bought LCR-T4 MC328, and I got confusing results. Below are my test results.

                          Aneng ST182 Meter.

                          Diode mode.
                          MBR3045CT:
                          Diode mode
                          Pin 2-1 - 0.150v
                          Pin 2-3 - 0.150v ...

                          Busted/cracked Light diffuser plate Samsung UN55NU7100
                          by lfhlaw
                          I was attempting to replace the LED lights on an Edge-lit Samsung UN55NU7100...While removing the sheets and the light diffuser plate which already had cracks at the bottom. The plate bent(more than I'd like) and broken in half.

                          1) Is it still usable if I can put in back into place

                          2) or Do I have to find a replacement diffuser plate and can it be any diffuser plate from a 55" Samsung LED TV or specific to my model?

                          3) can a new plate be purchased from Samsung?

                          Corsair RM 750 blown schottky diode near ES1DF
                          by iyas132
                          Hi there, i am currently diagnosing my corsair rm750 that wont turn on, after a power trip.

                          Before the power trip, previously i need to push power button on my pc case quite a bit in order to turn the pc (and power supply on), however after the power trip now i cannot turn the pc on at all and i opened the power supply, and found out some of the component(s) are blown. (picture attached)

                          My current diagnostic is that the (schottky) diode marked "SF" in the 5Vsb circuit are blown and possibly the ES1DF diode too.

                          Can anyone help me identify the component...
