I've got a 46" Philips projection TV (46pp930217F) that wouldn't power on. I made sure that it wasn't a powerbar issue or a problem with the outlet. I read some of the posts on this site and decided that I should check the fuse just inside the rear panel. I tested the fuse for continuity and the fuse seemed OK. I was convinced that I'd have to call in a technician to check it out...BUT...after putting the fuse back in and screwing the back panel on ... the TV powered up just fine. What the heck did I do? Did I somehow reset something by removing the fuse and replacing it? What would've caused the power problem in the first place? Thanks for any input.
