My 32inch lcd tv keeps flickering it started all the sudden


TRY THIS

    • 1 Turn the TV off with the front-mounted power button, not the remote. Unplug the TV's power cord from the wall outlet. Let an hour pass before plugging the cord back into the wall outlet. Turn the TV back on with the front-mounted power button and wait until it has fully restarted. Bring up a TV channel to see if the image being presented on the LCD screen is no longer flickering. A momentary power surge can cause the circuitry inside the LG-brand LCD TV to function erratically.
    • 2 Unplug the video cable from the video connection on the back or side panel of the LG TV. If more than one video cable is connected to the TV, disconnect all of them. Disconnect the other end of the video cable from the video source device that it's attached to -- a DVD or Blu-ray player, or a satellite receiver or cable box. Blow off the connections on the video source device and on the back or side panel of the TV with bursts of compressed air. Reinsert one end of the video cable into the video source device and the other end into the video input that it was connected to. Turn the TV back on with is remote to see if the picture is now free of flickering. A loose or partially connected video cable can cause the LCD TV's screen to flicker when presenting an image.
    • 3 Turn the TV off and unplug its power cord from the wall outlet. Place a power conditioner next to the wall outlet. Plug the power conditioner's power cord into the wall outlet. Plug the TV's power cord into one of the AC sockets on the power conditioner. Turn the power conditioner on. Turn the TV on to see if the picture is now free of flickering. The RF signals in the electric line that the LG TV is drawing power from can cause flicking through interference patterns being generated.

Unplugged my 32LV67U to vacuum behind it and now it will not power up. Yellow LED keeps blinking and I waited several minutes but tv will not power up. Worked perfectly until I unplugged it. Called...


That wall outlet may have frequent surges so try another wall outlet see if it turns back on. If it turns on be sure to use a surge suppressor and never plug the TV directly into the wall outlet. The AC surges will kill the power supply of the TV in short time. See if there's a kill-switch near the ac adapter of the TV if there is turn it on.Get a surge protector/suppressor then try plugging it back in the wall. If still no power then the power board is already damaged, you can send the board too me and I'll repair it for you or seek your local repair center.

Tv will not turn on


HI, check the wall outlet to make sure that it is live.if you are using a surge protector, i would pull the unit from the protector and, try a wall outlet. sometimes the surge protector will short out and, it will seem that the TV is the issue. if the protector is fine and, the wall sockets are ok, this will confirm a more serious issue that concerns the power sector inside the unit.

You will need to replace the power supply board or, fly back assembly in this case.

Unplug the power from the power outlet and let it sit for a few minutes. Then plug it back and it should work normally.

first things first- check the main power fuse; remove the 9 silver screws from the back of the unit, slide off the rear cover, and look at the main board right next to the power cord connection. There's a small, 6.3 amp fuse. Take a look at it; if it's blown... replace it.

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?

STATIC CHARGE


First thing I'd check is the powerbar. Did you plug the TV into the outlet direct? What caused the breaker to trip? If it was an overload by using too much current, there is a possibility that there is a loose connection in your house wiring causing arcing and the interiference lines you're seeing on the display. You may even want to try the set in a different outlet if the powerbar checks ok, and if the set then works fine, get an electrican ASAP!
