    Hisense - 50K3110PW

    Tv came to me with a not turning on issue. but when I plugged it in to see what the issue was the tv worked as I was watching it for about 3 hours it turned off the backlight and continued playing sound, I restarted it but backlight would stay on for a few seconds after this attempt.
    So then I pulled it apart and this is what I found.

          Extreme High Current & Low Voltage Short Killer ??
          by DynaxSC
          Hi Folks

          I'm looking for a extreme high current short killer solution for a reasonable cost.

          I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
          After taking off the socket, the shorts dissappear again.
          The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...

          MacBook Pro 14" A2442 Short on PPBUS_AON but no short present when injecting voltage!
          by Stephen
          I check PPBUS_AON and there is a short present on the line, the computer shows a short when testing for short to ground, so when I inject voltage into the line, I get 0AMPS so no short is showing up. I have replaced a blown cap on this board that exploded and tested for the short and it is now removed. Any suggestions? I tested voltage at the line when the fuses are connected and I am getting 1.2 Volts at the line.

          Acer Nitro 5 LA-L181p power LED turns on by 5 secs (Short on PCH rail?)
          by Victor Moreira Silva
          Hello everyone,

          I'm trying to repair my old Acer Nitro 5 (AN517-54-55T5). I've already bought a new laptop, so this is more of a learning project. For the experience, with no high expectations of success.

          Well, my decice specs are the following:

          Model: Acer Nitro 5 AN517-54-55T5
          CPU: Intel Core i5-11400H
          GPU: NVIDIA GeForce GTX 1650
          Motherboard: GH51G LA-L181P Rev:1c

          The symptom:
          When pressing the power button, the power LED lights up for about 5 seconds and then turns off. Initially, the issue was intermittent: sometimes...

          Help me find the short circuit on this WORKING Nvidia GTX1650
          by aaronkatrini
          Hi all,

          Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.

          Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...

          9th Gen Dell Optiplex Micro PC motherboard repair: Short Circuit?
          by Geeker007
          Hi All, I have a 9th Gen Dell Optiplex micro PC motherboard which doesn't power on. When I connect the motherboard with power adapter, it goes into safe mode and turns off. So from info I have gathered online, it looks like there is a short circuit on the motherboard. So can you guys help me with figuring out the issue?

          I am new to electronics repair, so my queries could be naive but I am ready to learn.

          So I have a multimeter and a solder with me. But I can try to get a variable voltage power supply with a thermal camera as well. From what I seen online, best way is...
