I need the code transistor Sapphire HD 3850

[rrs_br]

Could someone help me? I need the codes of the two transistors Video Card Sapphire HD 3850 AGP. This photo is not of my card, is the clearest I got on the web to find out. Sorry for my english.

I need this information because the transistors of my card is damaged and not a way to know what is the code.

Do you need the code on the chip, or in white next to it?

 

[rrs_br]

The code chip. Only the chip is damaged.

mate you need an electronics engineer. so unless you very lucky and 1 sees this post you might be better off trying an engineering forum. http://www.theiet.org/forums/forum/categories.cfm?catid=222 give this place a look...

I can get you the code, but I need to find a magnifying glass as it is very small. Ill tell you once i can read them!

Zoiks! That is some tiny print - the top one is tough because it is just etched, not filled in with white so I need to look at that more carefully but

the bottom one has what APPEARS to be (as best as I can make out) 5 or six total characters "1AM😛" above a single dot but laid out with the last two characters oriented differently so that it looked at first like it might be some other pictoral language character with "1AM" and then "😛" rotated 90 degrees counter-clockwise so that the two dots of the colon are beneath the P laying on its back -all of that above a small dot right beneath the point of the "M" in the middle. If that doesn't make sense, I will try to upload a diagram of it

And the top one appears to have 6 characters- four oriented horizontally and the last two vertically in the same manner as described above - " A6EA 1R" Also it appears that there is an underlining beneath the A6 and a "upper-lining" (opposite of underline, if you get what I mean - like a phonetic indication of pronouncing a "long" vowel sound) above the E. Again, if that is not descriptive enough, I will try to draw a picture if you need it.

Hope that helps- I've done similar type of searching for a burnt component on a dishwasher pcb, so I know what you are dealing with. =)



(you might try also searching for a schematic diagram of the pcb - that would have all the values of the components listed)

EDIT >> OOPS the characters I input got turned into a smiley instead - please replace the emoticons with the colon punctuation mark ":" and then capital "P"

" 1 A M" oriented horizontally and then ": P " going vertically ...

Section you want looks like this:

mate i have had a look at a transistor catalog and nothing in there (contains thousands) that matches that part number.
you best bet to find the info you need will be on an expert overclocking forum where guys do hard mods to get there cards oc'd(including rewiring and parts exchange)
or a hacking forum (yes a proper hacking forum not a hack site for software) where guys mod circuit boards and build things by hacking them together (the real origin of the term hacking).
from the info i found, they look to be multi switch general purpose transistors but what make and model i have no clue.

Ok guys, thanks for voxleo and HEXiT help. I'll decide together what a technician will do, I'll post the results and photos in a few days.
