Help! Killed my Parhelia!

[Gohan]

Hi there, today I killed my Parhelia. I was removing the HP80A cooler and brake a SMD. In the attached picture the SMD is showed.

Can somebody messure this SMD so that I can replace it.

Think you can get a closer shot of the part?
I won't be able to check until I get back in work Monday. A rough guess from the pic and pad size of the part, its probably a Ceramic Capacitor for one of the voltage regulators, but I'd be surprised if the board doesn't work at all without it (unless its the only filter cap at the output of the regulator). Probably something like 2.2uF, but I don't know for sure.

Gohan, are there any markings on the part?

If you want to make a better picture - put it on your scanner- this make a very good picture. We may be able to identify it from a good picture. Mesuring it may not be possible - because of other components connected to it.

Here is the closer look:

Perhaps you might ask Matrox directly...

Defenitely a capacitor.. chances are that C794 is the same value as C797, if they are both used on a DC supply line.. hard to tell without having a card here.. If only I had a Parhelia, I could measure the value for you at work. I wonder if Matrox would give you this info

[rylan]

I'll let you know the value of that cap on Monday. Rough guess from the size (1206 package I think) and voltage its probably going to be in the 4.7uF to 10uF range.

Looks like you for certain cliped C800 as well as perhaps one or two other things...

[Gohan]

I believe on the 128 BM Version are many free places

@rylan: Great Thank!

C800's just got some wierd looking pads, no hints of a violently removed capacitor there. But, look at those big square grids of solder points, you knocked all your RAM off! Seriously, I hope you get it fixed Gohan. And, just out of morbid curiosity, just how did you knock that little part off anyway?

[DGhost]

Yeah.. i just checked the back of my board and there is nothing there... the darkness of the picture made it look like there were some pieces still there... doh...

Don't know, after removing the heatpipe cooler I stored the card somwhere on my desk. A few days later I was looking for the points for the voltagemod, and suddenly I saw that there was something missing.

In the meanwhile I've increased my solder skills by solder a voltagemod on a GeForce3

Sorry I didn't get back till now.
I removed C794 from the board and measured as a 1uF cap. Its a ceramic type capacitor, I don't know the voltage rating etc, but to be safe try to replace it with at least a 10v rated part, with X5R or X7R dielectric.

[gt40]

Is this polarized, I don't see any markings on the board?

edit :Actually being ceramic type this this has answered the question.

THANKS! We will see if i get this baby running again
