If, when the back has been removed, you see some alu cans with plastic film printed wrappers, and the tops are bulged out, they'll need to be replaced by suitable very low ESR replacements. But that will generally need a full blown soldering station ($100 and up) and some expertise at soldering. If you have both, piece of cake, if not, take it to someone who does, or replace it. Modern led backlit monitors are generally brighter and use less power.
