Hello, I'm following this procedure because my MacBook isn't turning on due to a failure in the MagSafe DC In board, it was not charging the battery and therefore no power going in. The case was broken duirng warranty and also the MagSafe power adapter was replaced. Now it is failing again. This is an old late 2006 MacBook. Does your Mac powers on, do you hear the chime sound? or you are stuck with a hardware failure?

my MacBook charges the battery and powers on i dont hear a chime and it turns on but never starts
