A-Trend ATC6254M obtained... need help!
28.01.07 at 04:07:23

Today i got my A-Trend ATC6254M Slot1 Mainboard with 3dfx Voodoo 3 3000 16MB onboard!

but it does not work. i found the failure very quickly. A burned up Mosfet Sad

I found nothing of this in the ebay auction Angry

I will ask the seller what he "thinks" about this.

Anyway, when i boot up the system the cpu without cooler doesnt create any heat, so the cpu doesnt get voltage...

Do you think i can replace that mosfet with a similar one from another slot1 board?

That might help, since it would sound logical , if you would replace a broken part with a good working new part, but to be honest i'm not that technical heh.

I hope you get it fixed mate, it certanly is a nice Mobo, you could otherwise blame the seller, he should of known this problem, wierd on that part though heh Undecided

Looks like the mosfet is the same one as the working mosfet above it... Wink

Writing reads:

F 9928 (F = Fairchild Semiconductor)
NDB6030L

1. So I Googled and found THIS if it helps...

http://www.tvservice.org/components/FCROS1.pdf

...just open the PDF and search for NDB6030L Wink

2. THIS page has some info on the specific mosfet (unfortunately the datasheet it for members only!) Roll Eyes

http://www.digchip.com/datasheets/parts/datasheet/161/NDB6030L.php

...but most of the info you can read there anyhow! Wink

3. THIS page seems to sell the part you need (although it's in German, so you might need a translation page) Tongue

http://de.farnell.com/jsp/endecaSearch/partDetail.jsp?SKU=741449&N=0

...if you do need translation to order, use HERE

: -

http://translation.langenberg.com/

...well, I think that covers everything...I'm going to bed now! Roll Eyes

JOB well done methinks! Grin

Oh, GOOD LUCK WITH THE MB! Cheesy

Hope you can get that sucka' working! 8)

Also, remember that some mosfets are static sensitive! Shocked

Reply #5 - 17.02.07 at 00:30:37 It should be a piece of cake for anyone with a little experience in soldering to exchange that burned transistor. And I think it's very easy to find that transistor in other regular motherboards or just as is in a store that sell electronic parts.

Reply #6 - 17.02.07 at 02:08:47 yes i am already in contact with one guy. i hope he can fix it. i want to test it. it offers FSB up to 150Mhz which is really nice... okay the PCI and AGP will rise but i hope at least at 133Mhz FSB the PCI is fixed...

I know it's not as good as the SB AWE32 but a darn good on-board sound solution
