    Can a cracked plasma panel cause X-Main to short out?

    I got my hands on RCA Plasma 42PA30RQ. According to the owner (and they could have been lying) the TV worked fine until they cracked the screen. The screen does have a visible crack on the inside. When I looked inside the TV, I have found that X-Main was shorted out completely.

    In your experience, and for my future reference, can a cracked plasma panel cause X-Main to short out? How about Y-SUS or its buffers?

    Thanks

    Generally no. The X-main is a common fault on these models though, so it could have been bad.
    I've found plenty of TVs with cracked screens and bad boards... can just be down to the previous owners smashing the set in frustration!

      Yes.
      I have one .Found x main with igbt transistors shorted I replaced with all good to board.
      Then disconnect y board . Then turn on tv with x main. xmain is short instantely.

        Running some X/Y sustain boards without the ER path CAN damage them anyway (energy recovery chained between boards.) I damaged an LG PDP this way myself.

          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...
