Many LED TVs and other electronics have bad capacitors on their power supply boards. You can visually inspect them by opening the TV and looking for capacitors with bulging tops. If you see any, replace them all in the power board section. This should fix the problem. Check to see if your TV is still under warranty first though.

Why does disc tray open randomly Samsung ht-em54c


I had the problem of the disk tray opening and closing randomly but finally fixed it. I went thru a number of steps so I don't know which combination or individual step fixed it but I think it was changing the HDMI cable from the TV to the Blu ray player that finally fixed the problem. Previous to that I had removed the disk player and got the audio to work with only the TV and used one of the HDMI inputs as the output from my PC. That way I could play DVDs on my PC and run it thru the player to get audio in the speakers and video on the TV. Every once in a while the tray would try to eject (even though the player was not there). Finally I changed the HDMI cable to an older cable, the one between the TV and the player and it started working! I then put the disk player back in the unit and it all worked, everything!! Good luck!

Suffering picture loss


If you must use HDMI, you need to run it directly to the TV from the source for video and use optical or coaxial digital for audio thru your receiver. The problem is HDMI firmware (which is not upgradeable) you have either version 1.1 or 1.2 or 1.2a. All have issues. Three years and running and HDMI still can't get it right! In techno terms it's a DHCP compliance issue (in the real world it's copyright protection) Unless your TV is larger than 50", you can run Component without any visual loss, the human eye can't detect it. Also, if your TV is older, chances are it's 1080i not 1080p, so, if you set your TV to 720P, which is the native resolution of 95% of all TV channels now, and it looks better than 1080i
(1080i = 540p)

I've been doing Home Automation now for 15 years and I've had the luxury of dealing with VGA, DVI, and now HDMI.They have all had issues. Personally I'm just as happy with Component 720P, just use good cables. Hope this helps the pain! If you need any more help, just post a comment and I can help some more.
