em análise Gigabyte GA-EQ45M-S2 (rev2.1) boardview and schematic

[charlyd]

hi i am looking for the boardview and schematic diagram from the Gigabyte GA-EQ45M-S2 (rev. 2.1 or earlier rev) board. the board doesnt power on a with the power switch but when i short the green and black on the connector it starts partly.

 

no cpu power no beeps.. so it looks like a short or no voltage on one part of the board.

my suspects are the southbridge (Intel 82801)and or ITE IR7820F

 

can somebody help me ontrack

Who can help me ontrack with this Gigabyte GA-EQ45M-S2 (rev. 2.1)  Mainboard?  It worked normal until one day i tried to power on and nothing? 

i struggled a few days before a bit with the power-on button because i build this board inside a 16900 Logic analizer.  perfect board for the job. 

so i bought an other ( same one ) for the analizer and the first board is now on my bench , sympthon:  doesn t start. 

 

i am still looking for the schematic ( hoped to find it here but i doubt) and now diagnosing with a GA-EP45-DS3P schematic which is very simular. 

 

ok what can i tell from the board status now:

- with both connectors big power and 12v connected:  1 red led lights up next to the dimm. 

   When i start with shorting the power-on pins nothing happens, No Beeps?

 

- same sitution but now with the green/black shorted on the big power connector both (cpu & system) fans connected starts spinning, further NO beeps

  and the CPU stays cold.? 

   

  >> i have a bios post card ( TL631 Pro -debug Diagnostic Card ) in the pci slot but i only see 3.3v  and the display only show "00 00"

 

what can be the next step to check, i guess i am missing some power rails 

Must all mosfet have power in this stage already?  ( this stage = in standby stage)

@charlyd Good morning!

You created an unusual topic!! This is on a Pt.br Forum. You are writing in a different language, making those who would like to help use the translator because they do not speak your language. You could at least take the trouble to just translate using Google instead of leaving it to whoever wants to help you. It's a personal opinion that I think is worth a lot before rating a Forum as good as this one, since you came here to ask for help, it's terrible!
