Won't turn on.

The set won't turn on, when plugged in it emits a high pitched 'Eeeee' sound. Doesn't do anything else. No power up and a high pitch noise

    The Witch was right on the mark. The defective component was the horizontal output transistor (Q406) on the Toshiba TV model number MD13N1C.

SOURCE: Won't turn on.

If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. Could be anything from a bad startup resistor to a shorted horizontal output transistor to a bad controller. It is probably something simple but you will need to do some troubleshooting. Start with the low voltage power supply. Take care, and good luck

View sonic computer screen was dropped and now when you turn it on the picture comes on and then it emits a high pitched sound and turns off. any suggestions?


Sounds like you may have broke at least one of the lamps . The high pitch sound you are hearing is the high voltage that goes to it .

Panasonic TX32POL1 high pitched noise


The high pitch sound is comming from a power supply transformer that will resonate (or vibrate) at the operating frequency (12-14KHz).
This is usually affordable to repair -at least worth the estimate.
