My Emerson LE320EM3 tv wont turn on, it has not flashing lights and only makes a high pitched frequency when plugged in.


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Turns on then gives a High pitched Screech then shuts down even after totally unplugging it and reconnecting it blinks on then Screeches then turns off rinse repeat


are you talking about just the monitor of the computer as a whole? if you are talking about the computer then, there is something loose inside the case, which is causing the high pitched sound.

High pitched sound


Sounds like you have a coil or transformer that needs resoldered. Possibly in the hi voltage circuit but sounds more like a transformer in the switch mode power supply...

Sylvania Television shut down suddenly with a high pitch sound at the back


TV's have a circuit that monitors the high voltage and shuts down the set if it senses something amiss.
Figure on replacing the flyback transformer.
Hope ya fix it!
