It’s simple. Don’t do it. If you suspect your monitor to be faulty or broken, it’s best to get another one. You won’t likely find a computer tech willing to repair the insides of the monitor either, simply because of how dangerous it is. The fact is, tinkering around inside it could kill you, because of the amount of voltage inside. So get a new/used monitor, which saves you the hassle anyway.
