Re: no LED or power on Acer AL1716

i've replaced everything except C5, the large cap laying on its side...

Re: no LED or power on Acer AL1716

yeah, sorry about that. here are some pics of the board.

as far as i can tell, the 12v floats around 6-7v. i don't have access to a waveform scope at the moment for a better explanation....

Re: no LED or power on Acer AL1716

also, i have to add, i hear a soft "clicking" when the mains is plugged in. i can't really narrow down where it's coming from

i'm having an issue with this monitor that uses a TDK XAD819AR power board.

when plugging in the power board to mains, i'm not getting +12v on the 8-pin header. instead i get between 6-7v.

+5v is working.

160v on main cap

i've replaced all the caps, and verified the 12v regulator is working (IC53).

is there anything else i can check? or does anyone have a link to the schematic for this board? i've scoured elektrotanya and none of the service manuals seem to reference this power board.

thanks for any help you can pro...
