Was hoping someone could help me with some issues I've been having. Model:9P5514 C101 Chassis:PTV836 When I push the power button the green light comes on, there is a faint high pitch noise that comes on for a second towards the back of the tv. Everyone these days is going through hard times so I'm hoping to fix it my self, so if anyone can help me let me know. Also I have a Toshiba Model:51HC85 Chassis:TAC504 with with lines, was wondering can I use parts from one to the other to fix one?
