    I hate these XPS desktops!

    Who knows what killed this one! It had 3 dead UCC KZG caps (6.3V 3300uF) and when I put it all back, no POST.

    I get lights 123 green, 4 not lit and 2 quick beeps and the power light is green. Google gives little info on the meaning of the error code.

    Examining the mobo, I see that my soldering is just about as perfect as one can be with a hand tool but I find a tiny *tin whisker* bridging a pin on the LPCIO chip.

    Clearing the tin whisker did no good, same issue.

    To make matters worse, I was told after the fact that the machine had been unplugged for 6 weeks and had gone through a move.

    Luckily its a friends box so they aren't coming after me saying I killed their Dell. I test all boxes coming into the shop from customers but since this was a friend I had assumed that it was good save for the bad caps causing some funkyness.

    Assume nothing...test everything. This could have been SERIOUSLY expensive had this been a customer machine. Dell charges serious $$$$$ for these old i965 BTX boards.

    Im assuming the tin whisker killed the LPCIO chip...if so, this is my first documented case of tin whisker failure in the shop!

      Its an XPS400 series tower. Its not SFF, its BTX. I wanna say it was a 430.

      Its replacement is a nice box with a Seasonic PSU, a used eVGA 680i SLI mobo, a Q6600 CPU, 4GB RAM, a WD Caviar Black 1TB disk and a Geforce GTS 250. A very nice starting point for a games box if I do say so myself.

      Now the entire group back home can play Left 4 Dead.

        You probably already know this, but, Dell says for lights 1,2,3 but not 4 on the the XPS 400:

        Ensure that the cables are properly connected to the system board from the hard drive, CD drive, and DVD drive (see page 71).
        • If there is an error message on your screen identifying a problem with a device (such as the floppy drive or hard drive), check the device to ensure that it is functioning properly.
        • The operating system is attempting to boot from a device (such as the floppy drive or hard drive); check system setup (see page 113) to make sure the boot sequence is correct for the devices installed on your computer.
        • If the problem persists, contact Dell (see page 126).

        Sure the video card is working and you're not plugging into the onboard by mistake?
        Reset CMOS?
        Tried different RAM?

          Panasonic TH-50PX80 killed by lightning strike, help me save her!
          by SluggerB
          Yes it's a 17 year old Panasonic plasma!

          I was watching TV when there was a huge lighting strike nearby my house that shook the house. When that happened, the picture on the TV froze and the TV wouldn't turn off except by pulling the power cable. Now if you plug in the TV, it seems to turn on (it makes the turn on "clikcs" it always does, the red power light comes on but there is no picture, although I can see the back light around the edges. And the TV doesn't respond to the power button on the remote to turn off, and doesn't respond to the manual power button on the front...

          Accidental slip of the hand caused a spark on Capacitor. Is my PANEL killed in action?
          by Axis937
          Hi folks, newbie here. My intention on a working monitor was to test for voltages on the various pins. Somewhere near the ribbon to the monitor, there we 2 caps. One was reading around 5V and the other was maybe about 12 or 14V . Cant really recall. Then it happened. The multimeter kissed the 5v cap and the other cap. Spark appeared. NOW... the part where the spark happened ( Caps near the Last ribbon cable ) is now totally white. 1/6 part of the screen is white. From my little understanding , i came to learn that there are transistors inside the TFT panel. Could that be a issue then? I have removed...

          Asus G512 no power (BQ24780S problems)
          by Dannyx
          Good day folks. It's been a while since I repaired a laptop, so here's a challenge: a friend of mine asked me to take a look at an Asus G512LI killed by the liquid metal that got smeared all over the board when someone tried to clean it (I'm not blaming it on him - could have been someone before him). I was able to clean it enough to get it going on my own, without any help and thought I was all done, but then I ended up breaking it again

          See, the battery wasn't charging and the laptop wouldn't start on battery either. If you were to start it on AC and THEN unplug the charger,...

          Asus Zenbook Flip UX363EA killed by a cheap usbc power adapter
          by Gorflan
          Hi all, First post here
          Decided to up my game in electronics repair, and bought this dead notebook as learning material. The guy had already sold the screen assembly and ssd, I got the rest very cheap. Told me that he left it charging, and a power surge killed the non original USB C charger in use, and the note.

          Schematics seem to be non existent, only sites I`ve found with reference to this model are just trying to serve me malware.

          Been probing arround to reverse engineer the board, and made some progress:

          - USB PD controller chip (TI TPS65994...

          killed my bios chip?
          by agswireless
          long story short,
          I read the chip on ch341 and tired to figure out how to remove the bios password and couldn't but I wrote the bin back and now it doesn't boot, I get a white light on the power button for about 10sec then turns off.
          I tried to trouble shoot and Measure the bios chip.
          pin1 has 3v
          pin 8 VCC shows 1.5-1.8v
          did I kill the chip? on the datasheet says pin8 +3v power supply
