Question about LG 42LC2D 42 in. LCD HDTV

1 Answer

Our LG LCD tv is giving an intermittent flicker noise

Sounds like interference and starts when the TV has been on an Hour.

We have had it just over 18months, does anybody now how this can be fixed or if this will be covered by warranty? as we are assuming it won't be!

    i have had an LG tv for about a year now and suddenly it keeps switching off. the more you watch the quicker it switches off. any help.

    We have an LG TV with a similar sound problem. After about 1 hr or so, the sound begins to break down. Initially it just crackles randomly, but then continues to deteriorate and cut out until eventually it becomes unbearable. If we turn the TV off for 10 minutes or so, we can get about another half an hour of viewing before the problem returns. We want to get the TV fixed, but obviously need to find out if it's worth our while. Any advice welcome. We're not under warranty so will have to pay for all repairs, parts and labor.

It is a problem with the main board, and it should be covered, most people dont know this, but LG has 2 year manufacturs warinty on most of there tv's, and if they say it isnt covered, you usualy can talk to customer relations, and they will cover the part, but not the labor to put it in

LG 32" TV remote function fails to work intermittently. Works by using buttons on side. LG's remote for sound and DirecTV's remote for turning on station tuning. Batteries new in both remotes.


Try looking for the remote sensor. It should look a little like a camera lens or little red tinted window. If you cannot find it just give the entire front of the TV a good cleaning. Finger prints and dust build up can interfere with the signals. Do the same for your direct TV box.

Check the TV for dust inside the case by using a clean, dry source of compressed air to blow inside. Also go to all the inputs connected to the TV and tighten them.

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.

My Insignia TV model: ns-lcd26-09 starts flickering intermittently for a while after watching, quits after 20 minutes, then starts again.


Definitely sounds like a bad power supply. Especially if it's making any buzzing/hissing noises while it's flickering.
All Insignia products carry a two year manufactures warranty, which Best Buy will gladly service for you. If you're out of warranty, here is a link to a replacement part:

The TV could be wired to same breaker on the furnace. Or the cable line maybe cut or rubbing on electric line for furnace which can cause interference. Check each wire make sure there isn't any bare wire showing. good luck

My panasonic LCD TV's lamp light is flcikering.


Sounds like the lamp. Turn the TV off, unplug the TV from wall, wait for half hour. Remove the lamp and see, if it is fogy looking, this will give you an idea if the lamp is going bad.

Good luck

LG 42LC2DB LCD TV Flickers when Ps3 is connected via HDMI port


Make sure you have the PS3 set to the correct frequency for the TV. Many cannot accept 1080p / 24fps etc.

Try different settings.

I hope this helps.

HDTV interfers with my Police scanner


It sounds like HD mode on the TV operates at a different frequency (refresh rate) that then causes interference to your nearby police scanner. There's not much you can do about this--the HDTV design cannot be modified.

Your best solution is to try moving the police scanner further away from the TV. I doubt there is any kind of barrier that you can place around the scanner that might block the interference (the "noise" given off by the TV is likely omnidirectional).
