There is a problem on the monitor. You cannot perform the DIY. You have send it to a technician to repair the problem. They will adjust or change some components inside the monitor.

High pitch sound maybe an indicator of a defective monitor or a wrong or incompatible resolution setting of your display properties. The usual is that you have set the resolution higher than that the monitor can hold. Boot the pc in a safe mode. This will give you an option to set the resolution to that resolution accepted by your monitor, the usual is 1024 x 600 or so, avoid higher resolution than this.

It sounds like one of the capacitators inside the monitor is malfunctioning, these little things store a certain amount of necessary power and then discharge it when it is needed.  If it is malfunctioning, it could explain why it takes so long to charge, and why when you hit it, it suddenly comes on.
