Judging from the flaking, that CRT looks worn out. If you can find a nice one, replace it before good ones become even harder to find.
 
On these classic Macs, these problems usually come from a faulty analog board. Typically it’s bad capacitors or a flyback transformer. If it’s bad caps, this can be fixed but you may need to substitute some of the obsolete values and tantalum caps. If the flyback is bad, then you might as well get a tested/refurbished analog board and use this one for extra parts unless you can do the flyback swap.
