LG 47" LCD FLAT SCREEN
> IF IT WASNT DIGITAL HD I WOULD HAVE SUSPECTED HIGH VOLTAGE POWER SUPPLY BUT THAT DOES NOT EXIST HERE.
Well, not completely true; the fluorescent backlight is still a high voltage device, even if only hundreds of volts instead of kilovolts, and either the lamp(s) or the power supply for it (them) is causing the dropout of your picture.
When it does it next time, look at the screen from various angles, I think you will see that video content is still there.
PICTIRE SETTINGS
1. you should have a HD source, such as direct tv with HD channels
2. You need to connect this source with a HDMI cable
3. Make sure all the setting match from the source to the tv
LCD TV
This set should still be under warranty. Inquire about warranty service. DO NOT open it up as that would void the warranty. There is a problem with either the logic board or the panel itself. In either case, it will be covered under warranty.

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?
I have a LG dvd

Clean the Lens: Use a DVD cleaning disc to clean the lens. If the problem persists, consider professional cleaning.
Test Other Discs: Try playing different DVDs to see if the issue occurs consistently. If it's specific to one disc, that disc might be the problem.
Check for Updates: Make sure your DVD player's firmware is updated. Refer to the manufacturer's instructions for firmware updates.
Try a Different TV: Connect your DVD player to a different TV to see if the noise disappears. If it does, the issue might be with your TV.
The hum is simply the player trying to read the disc. It can't so, it spits it out.
Remember that prolonged use of a malfunctioning DVD player could potentially cause damage. If the problem persists, consider seeking professional repair or replacement
