Hello. A couple of weeks ago my Asus X550lc screen displayed horizontal lines and had a corrupt image, so I replaced the screen. After replacement, the laptop would not even power on. I took out the battery, held the power button for a minute, and plugged the AC in only, but still nothing. I then ordered a new motherboard thinking I may have shocked it during the screen installation, but after installing it, it still refused to power on. I then thought it maybe the AC adapter but using a millimeter I verified the voltages. Perhaps it could be the DC Jack, I thought. I also verified the voltages there. So now, there is power to the motherboard but it won't power on. No lights beeps or anything. I'm thinking that it's a DOA motherboard and that I should return it, but maybe you can come up with a possible solution. Thanks in advance guys :)
