As you can see on the top picture with the machine powered on, there is one of the screen driver chips broken resulting in a dead rectangle on the display. It is rather not repairable.

It is possible to solder regular SMD capacitors in place of those 3.3uF/35V boxes (they contain small electrolytic capacitors inside), but I would not recommend nor do it for the second time. It is too easy to break delicate traces and repairing them is troublesome.
