Hello, I have a phillips model: 32pfl4507/f7. Everything on it was fine then the screen went black and power won't turn on. As long as tv is plugged in it produces a very high pitched noise but no power to screen. I replaced the power supply board part #: BA21F0F01 02 5. Same problem. I'm lost and can't find answers online at all.
 
The power light does not come on at all. I installed the new power board and plugged in the tv and it made this high pitch noise without turning on. when i unplug the tv the high pitch noise slowly fades out. the tv is unresponsive to power. The power supply # you posted is identical to the one i installed. I am out of ideas right now. Do you have an idea?
