    Re: Say you got a free PSU from outside... and it was raining

    I had a wall wart, the kind with the black plastic shell. The thing got filled with water. I opened it and it with a hack saw. it was full of water and rust.

    I was thinking about fixing it, but I found another one with the same voltage. Now it's in my pile of spare parts!
    Disclaimer: Don't trust a thing I say-I am frequently wrong!!!

    I have tons of spare parts, some used, some N.O.S. ham transistors and caps. Message me if you need any parts.

    Some of the things I've fixed:
    60" Vizio-bad LED's. iBook G4: Resoldered VCC Plug. Geo Tracker ECU: Swollen / Leaking capacitors. Windows Laptop: Soldered broken LVDS wires. Dryer: Burned contact on temp switch. Oven in R.V.: Bad contacts in relays-Exploded by the looks of them! Samsung Oven: Burned contacts on Relays. MSI Motherboard: BSOD-Swollen capacitors, bad graphics card, Moved SATA Input from SATA 1 to SATA 2 plug

        I use mailing tubes as drying "tunnels" for PCBs. Fed from a small inline blower via flex duct. I temper the air @ intake w/ a small heater- air movement is important too! 55-75 CFM @ 115-125 for 3 hours minimum...

        Always get it clean before drying, especially in tube or other hi-Z ckts.

          by DJbapt59
          Hello everyone,

          I recently picked up a laptop that was about to be thrown away to try to repair it. I've tested quite a few things, but I don't know where to look anymore. Could you please help me?

          Brand: Asus Vivobook
          Motherboard reference: x421da, Rev 2

          Context:
          The person who gave it to me mentioned it might have been exposed to water, but they weren't sure. After opening it up, I couldn't find any signs of water damage or oxidation on the motherboard.

          The first thing I did was to connect the PC to a power supply: 19V stable and...

          Dell Inspiron 7506 Silver 2n1 - "HELLCAT 15" - No power
          by LimesKey
          Hi everyone, I have an Inspiron 7506 laptop I've had for a few years, and it'd occasionally have a problem where after I'd power it off, it wouldn't turn on again unless I disconnected, drained residual voltage by pressing the power button, and reconnected the battery. It now seems to be occurring every single time I shut down the laptop and attempt to turn it back on again. I have done all the common troubleshooting steps, such as completely disconnecting the battery & CMOS battery and draining the voltage and leaving it for an hour, and I've even replaced the battery. This is definitely...

          LG 55NANO77SRA TV – Menu scrolling by itself even after removing button board (Main Board EBU66792103)
          by ygorsan
          Hi everyone,




          I’m looking for help with a persistent issue on an LG TV model 55NANO77SRA, which uses the main board EBU66792103 (also used in LG UQ80 and NANO75/NANO80 series).







          🧩 Problem Summary:
          • The TV keeps scrolling through the menu or selecting items by itself.
          • I removed the physical button board (the entire panel with power and volume buttons) and also disconnected the flat cable (CN202) from the main board.
          • The remote control is not in use (batteries removed), and the TV still shows the same behavior.
          • I

          A3401 Gatorade Spill Best next steps
          by abajor
          I had a customer call me with an M4 A3401 her daughter spilled a gatorade into, and didn't tell her mom for about 2 hours.
          I had her bring it in immediately so we could disconnect the battery and I could dismantle it so I could swab the board with Isopropyl an dry with a heat gun.
          There was already some green copper corrosion when I opened it.

          I did a good first pass and dried off the board, now I'm going over it with my scope swabbing and poking at any oxides with my exacto tip.
          I brought out my hot air tool to evaporate the iso and caramelized sugars started bubbling...
