HI can I check anyone can supply this board view or schematics.
the problem i have : when plug into power supply it will on but no image. after i push start button then it will have image.
As this motherboard is not a conventional one, it uses acer own propierty psu and schematics i have problem trying to trouble shoot it.
1) the psu i tried has ps-on 4.5v. no purple cable of 5vsb or 12vsb.
it does not have vsb cable. i check the internal circuit of power supply. it does not have vsb transformer. i i think the psu is fine.
but the 12v appear even without pressing start button. when i press start button then the cooling fan can work.
2 ) next i suspect is the motherboard issue which i have not prior experience with the circuits of 12 VO motherboard.
I can find the circuit, but i am unable to get through the Russian website to pay for it. i think it only accept that area payment.
a board view will be good.
Previously i had also encountered Lenovo 12VO motherboard. Their 12VO is also not standard and its power supply had 12v when switch on power supply already.
I had a dell 12VO psu before. it works exactly like the said 12 VO psu with 12VSB.
can anyone assist in any way ?
