9600gt defect

Aleksander · Apr 8, 2012, 05:28 PM

hi!
i am having trouble with a card my friend gave me to test
the 9600gt
he said to me to post a photo of a part he replaced and ask in forums
so i will post here. also if anyone knows which is the name of the part
that would save the day

Aleksander · Apr 8, 2012, 08:17 PM

I forgot to add that the card is asus!

I'm pretty sure that's a transistor, but the soldering job looks very bad, I mean, the PCB line that goes to the base of the transistor seems to be completely ruined.

I might be wrong (I hope I am) but if the card doesn't work in its current condition it's going to be very difficult, at the very least, to fix it (remember, transistors come in NPN and PNP "format" so replace only with same part number).

Good luck tough.

Don't know what the part name is but the soldering job looks like a mess...!
If your friend wants a new card(he sure will)shoot me a PM

It is a diode as symbol "D505" indicates.

Aleksander · Apr 8, 2012, 09:30 PM

Ok, he told me that thing has 3 legs.
He has fitted in there 3 times 3 diodes so this is why it looks like a mess.
He doesn't know which diode is needed, so he looked at the others and bought one
exactly like D504, or D503 and so on.
But it looks like it is not like them!
Which one it is?
Or is it bad soldering?

This.

If someone gave me that card asking why it's not working without telling me that soldering work was done on it, I'd pin-point that diode and say that it looks blown/burnt.

Aleksander · Apr 8, 2012, 09:59 PM

Oh and the card works, but the problem is that it "crashes"
So is it soldering again?
Is it bad to try it out on the pc?

Swamp Monster · Apr 10, 2012, 06:36 PM

Sorry, I had not much time to explain in the previous post, but there are various possible configurations of diode arrangement in 3-pin sot23 body that you have there.
Also there are different types of diodes for different purpose (Schottky diode and "common type diode" for example).
I am not saying that it's not possible to repair your card, only that you may have to try out many configurations before you succeed.

Here are one example of possible diode configurations in 3-pin body: http://www.farnell.com/datasheets/27632.pdf

i guess not since its not connect directly to the power, but you may pay attention more when test it coz you dont know what would happen to the card
i ever saw repaired card that soldered and coated with Cyanoacrylate glue

I do not know what type of soldering iron your friend used, but that looks like a real mess.
Suggest that he gets a proper soldering station, some ESD equipment as well. Some parts are rather sensitive.

As I see, it looks like the soldering iron has burnt the diode. Usually the tip of the soldering iron should be rather small/thin, should look almost like the tip of a pencil.

This is a good link, I think it provides a good guide in soldering surface mounted devices.
