Having problems with your Flat Panel Televisions ?

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?



Answers :

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.

When i plugged my hdmi cable from my cable box to hdmi #4, it doesnt seem to receive any signal. the screen stays black. however, when i use the hdmi #3, it works perfectly fine. could it be that the port itself is defective? and if it is in deed a malfunction, what should i do next?

I connected my laptop to my LG 50PQ1000, and then my Blu-ray player didn't work - no mater what I did, the problem was "invalid format". I tried everything, including putting it on another TV - there it worked just perfect, but on LG no. I changed the HDMI cables, I tried all possible resolutions, no way. I updated the player - the problem remained the same. Now in order to watch DVD and BRD I put back the old cables, not HDMI cable.

So I went to play a dvd by removing the HDMI from the back of the HD cable box and plugging it into my DVD player, then returned it back to the cable box when done. Then the volume would not work on the TV, a plug symbol appeared in place of the speaker symbol ...but the lines and numbers appeared for the level of volume. What am I needing to do for the volume to return?
