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.

Re: Won't turn on.

So how do I fix it? I have some electronics experience that I've picked up over the years, so I'm not afraid to give it a shot. Aside from the risk of a good jolt, I know I can't make the tv work any less than it already does. So what do I need to do? Silly, you seem to have some ideas, I just need to know how to implement them into troubleshooting scenarios.

Re: 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

My tv won t turn on i just purchased it today i plugged it in and it won t turn on

Check the electrical outlet which the tv is plugged into. Make sure nothing is loose at the outlet as well as on the back of the tv where the power cable plugs in. Another thing to try is plug a different device into that same electrical outlet and see if it turns on. If it doesn't turn on, it could be a faulty electrical outlet. If you've tried both the remote & the power button on the tv, a shot in the dark would be to change the batteries in the remote.
You could always try calling their tech support at 1-800-256-2487. A last resort would be to return the tv from where you purchased it.

TV making high pitch noise, stop working.

High pitch buzzing and no picture

Your power supply, I mean the internal power suppy could be faulty, if you know how to deal with it, check it for abnormal oscillation, or get some help from someone who knows how to repair it.

High pitched sound

you can fix this if you are very careful. it is call a high voltage leak. inside of the tv, close to where the power comes in will be what is called a high voltage transformer. if you are electrically inclined, unplug the tv, take the back off and then hook the power line up and turn the tv on. with the lights off in the room and a flashlight handy, look at where the sound is coming from. locate where the sound is coming from and look very carefully(very carefull not to touch with your hands or head to any part) for a white-ish blue arc of electricity. if you can see this then that is where the problem is. to fix it you will need to put something in between the two places that it is arcing from. a piece of plastic or silicon putty or anything non-conductive will work. again, be very careful or you might get the dogsnot shocked out you.

18 Mo old Samsung CXM2785TP made high pitched noise and lost power

The high pitch sound could have been the flyback transformer. check the horzontal output transsitor if is gone the tranfomer is sure to be gone . Tranformers are varying in price are the transistors can also vary you could be looking at around 150.00 plus labour.

High-pitched noise when I turn on the tv

No I think your problem is the horizontal output transistor blew out an that was a result of the flyback transformer going out or blowing up.. Good Luck TO you.
