welcome to my shop: 1.The soldering iron can't touch the components for a long time(1.0 second), otherwise it will damage the components. 2.Pay attention to the positive and negative of the components. 3.Make sure all components are in right direction and right place. 4.Avoid pseudo/float welding.This is very important.It will cause the components to not connect to the circuit. 5.Please melt each welding point again if it doesn't work 6.It is strongly recommended to read the installation manual before starting installation!!! Notes: 1>.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
