It will take more than one book to learn electronic troubleshooting and repair. I have at least 50 books, plus various cross reference guides, cataloges, ~40 years of background and I only do electronic repair as a hobby.
Having said that, Google for the Sci.Electronic.Repair FAQ. There is a special Monitor Repair FAQ section (it is fairly lengthy), however my link seems to be failing. Drexel Univ had (has) the original FAQ, but there are mirror sites. Parts of the Monitor Repair FAQ are a bit dated though still valid and relevant.
If you have a modicum of electronics knowledge, it's a good place to start. Even if you don't know the difference between a resistor and a capacitor, it might be worth perusing just to understand a little about troubleshooting and repair techniques.
Good luck!
