No power on. Faulty mainboard suspected

I dismantled the acer 5742g to replace a damaged lcd connector. After having Reassembled everything, the power on button produces no effect. Only the AC power supply indicator is on. The cooling fan doesnt work. I tried with both AC and battery supply. I suspect a broken mainboard. Do you have any advice?

If it worked before you replaced the screen then you might have forgot to connect the power board cable or nocked it loose when working on the screen.
