I disassembled an Asus A7S-A1 2 nights ago for a BGA reflow. Following reflow I inserted a stick of RAM, had the heatsinks re-seated with fan, attached the power button to motherboard and then connected the battery to test if reflow attempt was succesfull... good so far but heres where it all went wrong, lastly I connected the display data/video cable to the board, and a faint pop then burning smell and now no power AT ALL, no post, nothing.
Obviously I should have had everything connected AND THEN lastly the battery.
Anyway thats where I am now. It wasn't the inverter because the loogicboard would still get power im assuming and fans would still spin up etc...so I am guessing that its something on the motherboard (possibly around where the display connects as that is where burn smell seems to be)
What should I be looking for exactly? I realise its, "look for something burned", but anyone know specifically? I can't visually see anything burned.
Should there be some kind of embedded fuse perhaps?
For the record I have a solder station, multi-meter etc...and am not afraid to dig in.
