Re: Emachine Mess

wow im open for suggestions on a better way to test the caps and or the fets. im sure that im doing it the wrong way. so far all i have for test equipment is analog volt meter, and a digital multi-meter. again any suggestions would be appreciated. thanks

Re: Emachine Mess

im using a method i found on this site. vom. starts meter bumps to the right and then gradualy moves up until it reaches infinity

i also used the method on this site for checking the fets.

i hope this helps


and yes that is a picture of the power supply... but its blown so it will not be going back... hehehehe

Re: Emachine Mess

the power supply is a bestec 250 watt

Re: Emachine Mess

ok the customer describes the problem like this. "I was working on the internet an it just cut off" or "i went to fix something to drink and when i got back, the computer was turned off". I know basically that they have bad motherboard. We have a company that sells us these boards for alot of $$$. we also have to send the bad ones back and they fix them... the board symptoms are ;all the fans will power and the led's but no video. i have tried with the board out of the case, new power supply, different memory, different processor, and agp video...

Ok so i work in a computer store. we have a pandemic of emachines comming in. common boards are fic am37 and au31. i have tested the capacitors and the fets. forgive me for being a noobie. both the caps and the fets test ok... i tested both according to posts i read on this website... hehe. what else could be a common factor between these boards. Most of the people that we buy our boards from know about this and charge a fortune for them. im sure that its just a vrm or something... any help from you guys would be great... thanks..
