MSI 694D Pro2 - Does Not POST After Recap

[opaque]

I just recapped my board with Rubycon MCZs - when I flick the power switch, the 4 LED lights in the bracket at the back go RED (Manual says CPU problem - but the CPUs worked beforehand). Fans on CPU spin for a second then spen down. I've tried using just one CPU. Any clues? Thanks

Probably bad VRMs... try a cmos clear anyway before giving up.

Measure the voltage on the capacitors near the CPU; also check for accidental bridging somewhere or other soldering problems.

Thanks for the advice, Randy... What are VRMs?

i've never used a multimeter on computers before - only in Physics labs. Do I just power on my machine and bridge the voltmeter across two nodes so they are in series? What should the voltages read?

FAQ - Testing VRMs

make sure you attached the cpu heatsink properly.

Thanks for your replies. Do these VRMs just break by themselves? I've taken great care in removing and replacing components to not knock other parts of the board.

Is there anything I can test without buying a multimeter? I'm a newbie when it comes to electronics. And with the 20 or so pins the VRM has, which two do I put a voltmeter in parallel to?

Edit: I just thought what I did different. I tried out my new Coldheat soldering iron (I knew it wasnt a good idea ) - would the sparks be what caused the VRM to fry?

did the board work before the recap?
coldheat iron=crap.
the money youi wasted on it would buy you a dmm.
return it if you can.

Urmm? Applying high voltage discharges to motherboards = BAD idea. IMHO.

where did the sparks come from?

Re: MSI 694D Pro2 - Does Not POST After Recap

that coldheat crap thing can apply 6v across the tip.i can see it sending that 6v into an ic if you touch it just right.
not good.

Yep

> coldheat iron=crap. the money youi wasted on it would buy you a dmm. return it if you can.

Doubt I could; Hong Kong works differently than North America - the shop comes before the customer =\ So even though I pay much less for Rubycon capacitors (see other thread) I suffer crap customer service and no aftersales service. I should've just waited till I flew back to Canada before buying the cold heat.

> where did the sparks come from?

according to the cold heat site, "It's normal for it to spark"


So what could have failed? Would it be the VRM?

(P.S. I am away on Holiday for the next 9 days so apologies if I don't reply before then)

Re: MSI 694D Pro2 - Does Not POST After Recap

it sparks cos it isnt grounded.

did you buy the MCZ from pcbulb/waifong?

shit everyone is going on holiday....i already been on holiday earlier in the year, now i am missing out.....

Re: MSI 694D Pro2 - Does Not POST After Recap

Yep, that's where i bought them.
