You need more than a schematic and a DMM.
You need some basic training. Don't be in a hurry to jump in and fix
something.
Before you can fix something you need to know how it works and what is
happening to make it not work. The fixing part is easy most of the time.
When you troubleshoot you are looking for a reason the unit doesn't perform
as it is supposed to.
TV's are very complicated and require more test equipment than a schematic
and a DMM. They are also very dangerous.
