Flickering black screen LG 37LC2D-EC

My Tv has suddenly started to flick between a black screen and picture after it has been on for approx an hour. I have also had a message of "This display does not support HDCP". Does anyone have any idea whats happened? The HDMI cable port is connected to Sky+HD box and I have eliminated fault of HDMI cable as it works perfectly on another TV. I have eliminated Sky+HD box as it works perfectly on another TV. Could an over air/sky/playstation update have messed up the TV?

SOURCE: LG 42LC2D-EC NO SOUND ON HDMI

your setting for source of the audio is probably defaulted back to original setting in receiver. reassign audio input and problem may go away. it sounds like its not in the tv. i assume you have a receiver and are not trying to listen with speakers in tv. is this correct? if you are not using an amplifier, you may need to go to the tv menu to make sure the audio source is selected as the hdmi input. should take a bit to read thru the manual, but it ought to show you how to accomplish the correct settings.
let me know if it does not.
good luck

SOURCE: Connecting to HD TV

This TV has no HDMI input socket. It Has a DVI input socket. Therefore you will require an HDMI to DVI converter adapter or an HDMI to DVI cable. The DVI is video only so you will require audio cables from your Sky box (Audio L and R ) which will connect to the back left of your TV (Audio L/R sockets next to the s-video and component video connectors)

It sounds like the TV is having sync issues with your Sky+HD box. HDCP is the "High-bandwidth Digital Content Protection" that is used between components. It requires a sync between the devices to ensure that you are not trying to "steal" the video content you are watching. This intermittent message and blacking of the screen is good evidence that this is your problem.

Even though the HDMI cable worked fine on another set, I'd try a new one anyway. Some TVs and components are more sensitive than others, and a weakened cable may not show a problem on one set, yet show it on another.

Barring the new cable not working, check LG's website for a possible firmware update for your TV, and also try using a different video source, like BluRay and see you have the same problems.

Beyond that, it may just be an issue with the TV itself starting to die.

No sound and no picture


The green indicator merely lets you know that power is getting to your TV. The absence of picture and sound could be due to power supply failure

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.

could be the power supply card(s) is unseated..open it up if you dare and re-seat and/or maybe remove and clean the card edge connector contacts with an eraser
