Today my power went out for a split second and came back on I turn my TV back on it makes a high pitched whining noise and the screen wont turn on. Cant add picture but model number is MW30G71.


unplug your tv. let it sit for a good bit. 1/2 hour did your power just go out or did you have a power surge then no power. surges cause the grid to go down for a second too and that causes problems too. surge protectors are good for everything. also are you on cable? if so have the cable company check they're filters into the house may be an issue but check the tv after a half hour unplgged and then plug in and turn on normally? sometimes it needs a reset time period before the fuses inside will reset themselves.

the compressor that pumps up the air suspension does make a horrid noise, and if you can turn it off, like I could in my crown vic, just long enough to see if that is indeed the compressor making the noise you hear, then try that. My switch was located in the trunk.

Tv shuts off tv/video doesnt work


that is a indication that a fault is about to occur, dont force that tv take it to a technician before it switches off completely, a power supply is supposed to be checked.

TV turned off by itself and now it won't turn back on


If the tv has nothing happening at all when you try and turn it back on including any noise, your power supply is broken. If it is still trying to turn on or does make noise, an internal component has come loose or been knocked off, most likely to your picture tube.

LG 47" LCD TV - 47LC7DF Clicking Noise


I was told that these clicking noises (which happen on my Magnavox LCD too) were due to the "power required" at the internal switch. Seems that the power required to immediately turn on the TV is too much for a standalone household outlet, so it "surges" power in a series to get enough there. Hence, the clicking sounds are actually mini power surges to send more power to the internal circuits to turn the TV on.

If your set is like mine, these noises generally stop after a minute or two, correct?

Panasonic TV


The power surge has caused a failure of an internal component. If it is making this noise it is possible the line output transistor has failed. I would advise calling a service repair centre & have someone there take alook at it. All being well this may be the only problem. Power surges can sometimes cause other faults.

Tv wont power up makes a noise but no picture


Your power transformer is likely shot. It'll cost at least $200 to have it replaced. Someone can come to your house to diagnose it. Usually costs around $65.
