I have a PNY geforce 4 ti4200 64Meg graphics card which has sustained some damage. The damage is not very extensive and I was thinking to repair it myself. I'm proficient at pcb repair...whoever, i'm not good at finding proper components w/out a parts list.
I took some close up photos of both sides of the pcb where damage has been. They can be seen here....
-------------------
q905 and c1267 are smoked. c1371 is slightly mushroomed on top and should be changed too.
c1371 and c1267 are identical: Barrel caps 6.3V, 1000microFarad, 105 degrees C,...the vendor is apparently Canicon.
q905 has the markings.....
230 (beside this number is a small "on" w/ a circle around it.) D30 N02not sure how to cross reference these numbers. I'm assuming that one would be the date code.
-------------------
their is also one trace that is damaged(open). This i could easily repair.
I just need some help in finding the transistor(s) and the cap.
If someone could please help me on this subject or nudge me in the right direction where to look, this would be appreciated.
thanks you,
