Help identifying overheated circuit board spots

[jt20]

Ok, total newb here.

Trying to fix an LCD TV with no picture.

I think I found a slightly swollen cap and what appear to be burnt(?) spots on the power supply board.

Yeah, they're not really burnt, but my understanding is that boards are coated after assembly (?) and if something gets too hot, this coating deforms / wrinkles (right??)

My camera sucks, but in person, this coating is clearly disturbed in these areas (circled in red).

my questions:

Are my thoughts thus far correct about overaheating and the coating?

Are the little, tiny rectangles resistors? There numbers on the board are prefaced with an "R".



Thanks

The coating stuff is just leftover flux.

Yes, the black square things are resistors.

What does the top side of the board look like? (pics?)

Is the mains fuse blown?
