Monitor Help.... Horizontal rolling and Heat

I am going to take a Hewlett Packard monitor apart soon. When
it is in operation for a while the screen will start to wave and
roll. Excess heat seems to come out of the top vents.

My thoughts are to visually inspect for a cooked looking part. Maybe
an electrolytic. I don't really want to spend a whole lot of time on
it but am going to at least take a look at it before chucking it.

Any advice on what to look for?

Excess heat is meant to come out of the top vents, but if you're getting
excessive heat, that's different.

If you need to ask for advice on what to look for, then disassembling it is
not recommended.

I am looking for advice from someone who has experience with monitors.
I have never had to touch a monitor before. I have however worked on
many electronic gadgets successfully for years.

Unlike some (maybe yourself) I am secure enough in my abilities that I
will not hesitate to ask for advice.

But not secure enough to take it. There's a reason the experts here caution
people with less experience to reconsider whether they want to work inside
a monitor. People who are accustomed to working on circuits powered by
12 volts might not be comfortable working around a potential 30 kilovolts.

If that was true (concern for safety) then he would of mentioned the
30kv.
