Need some help with a broken motherboard (hardware problem)

post #1 of 11
Thread Starter 
This is a DFI LANParty NF4 Ultra-d board. It suppose to be a really good overclocker for a socket 939 board. Anyways, back in the day vuxdu broke it and bought a replacement. Now I took a look at it and found this piece broken. Can anyone tell me what it is? Perhaps even how to replace it to see if this board still has life? It would be a fun thing to try and if it works, then I would have a heck of a good board to play around with.

The piece in question is in the red square. I also took a shot of it after looking closer in a microscope and yea it definately looks to be the problem.

I believe that's a really tiny diode, someone correct me please if im wrong. even if you happen to find one to replace that blown out one, good luck soldering it in.

Its a diode alright, though i have no idea what type. I suppose if you were skilled enough you could sauder it into place. if you are planning to attempt repair just make sure the sauder at one end doesnt meet with the sauder on the other that would defeat the purpose of the diode and likely damage other components of the board or installed on the board.

I believe its a resistor .
You may be able to fix it. Just put a line of solder joining up the two contacts where the broken part is. It still may not work, and it may damage stuff - but it may be worth atry. I don't think you will be able to replace it properly though.
Of course I am by no means an expert - just seen it done before.

Its a resistor for sure, if you could find out the specs on it you could solder a normal size one in its place. I would have it repaired though. You will never get the small one back on properly.

I'm actually pretty sure it's a tiny ceramic capacitor. And yes, it's broken.

Got any electrical engineering friends? You need to first find out what the part is. I'm quite sure it's a capacitor because of where it is, but when you're working with parts this small you can never really tell unless you're particularly familiar with the parts. Luckily there are identical parts nearby. Get someone with a nice multimeter to measure the electrical properties of the part, most importantly capacitance and resistance, because we're trying to figure out what this thing is. You can find those things everywhere online and in electrical engineering companies.

You'll need a microscope and a decent soldering iron to get the part in.

Or you could just send me the board and I'll do it myself

Lol mixed opinions, either way, a resistor is designed to resist the flow of energy while a diode is primarily used to allow current to flow in one direction but not the other. either way it can be professionaly replaced or you could attempt a jimmy rig

Thanks for all the thoughts, unfortunately I think this board is unrecoverable. Using a his res picture I found on google and an identical looking part I found on something else. I removed it off the donor part and stuck it on the mobo making sure the silver ends contacted correctly. Even switched it around to make sure polarity isn't wrong. Board still doesn't start up any different, just flashes four red lights and shuts down. Whatever the problem is beyond me, I'm sure now that something else shorted out.
