Dead MOBO!! Need help!
Hey guys.. i got a mobo from a guy on another forum.. he said it just stopped working one day.. i assumed this was the power supply.. took it out and put in a new one.. nothing..then i checked the fuses.. the ps1 fuse was blown.. i got it replaced.. still nothing.. tried new psu, switch controll, eject cable, eject button..Still nothing.. all other fuses on the board are good!!
PS: There was never a mod attempt on teh board and doesn't appear to have problems from water or anything! Looks like a good board just that it dont power on!
Thanks and please help me out! ALSO: V7 system!
did you check all the fuses ?
Does the red light come on atall
Have you checked that the psu is delivering 12v ?
checked all fuses.. tried 3 different psus that all worked in other systems.. im not possitive how to check the how much power the points are delivering.. sry kinda new.. i took it to a guy nearby and he soldered in a new ps1 fuse all others were fine.. still nothing!
So its not the psu!!
No redlight.. no power at all!
to check the power, put a multimeter on the outter (or inner) pair of legs from the psu, it should deliver 12 (if it say -12, you put the probes on the wrong way round ;) )
But it doesnt sound like its a psu probelm
Have you check the new ps1 fuse, it may have blown again - so there may be a short on the board somewhere
And is the ribbon that attaches the power buttons seated properly, if this isnt in properly, or the ribbon is damaged, it may be causing your problems ....
