My ceiling lamp died. Is there any way that I can change this light bulb?
The white wires are soldered into the ballast inside the box. The ballast also is wired to pins connect to the bulb. So I guess I have to change the whole thing, both bulb and the ballast?
Also how to disconnect the connector on the left?
It looks like it just pulls down, there are usually little springs that keep it in place. Like the one pictured below
If you pulled the wire from the socket then the best way to repair this is to replace the socket unless it happens to have screw terminals on it (I doubt it). If you mistakenly removed a wire nut then you can easily correct this. Wire all black wires together, all whites together, and the grounds together with wire nuts (often they are supplied with the fixture).
The lights should be wired in parallel (white-to-white, etc.), not series. Do not wire black-to-white and black-to-white.
If you are unsure of how to make this repair then the safest thing to do is replace the fixture and/or consult an electrician.

Usually, with those types of "2D" fluorescent tubes, you grasp the central plastic portion and pull down firmly. There are pins in the underside that are gripped by a receptacle in the fitting.
