Question about Panasonic PT-47X54 47" Rear Projection HDTV-Ready Television
I dont know what exactly happend but the problem is that my tv it doesnt turn on or off anymore it has the power led on but no picture .. and also it has a little beep sound in the back of the tv inside... what could be the problem? any help please..!
A high pitch whine is typically the sign of a short. Its the switching power supply turning on and off at a fast rate and your hearing the unit "whine" because of the fast pace it does this at. Best bet is to have a tech troubleshoot it.
