LG Television 37LB4D "Rebooting"

TV periodically looses sound, picture. After a few seconds "noise" appears in the upper left of screen. After a few more seconds picture and sound return. During this time remote is non functional. Problem is getting progressively worse. Problem is worse when using AV input, but occurs with TV input as well.

Problem occurs randomly and is not reproducible. Frequency is from hours+ on TV input to seconds on AV input

I have 42" LG. It works fine until we use broadcast from air. TV random rebooting. I read a lot people have the same problem. I contact LG, they ask me to contact service to estimate repair cost.

Ours is crapping out just like yours. Picture goes out, "black and white squiggles" appear in the top left of the screen then TV input appears, then it either repeats or gives me my picture back. This happens with both the HDMI slots (tested all 3) and both Component slots. Seems like the bulb or a circuit board on the TV is faulty. What a piece of ****, never spending another dime on LG products. I did get it to come back by hitting the back of the TV with a good slap, but it gets really annoying.

LG LCD 42" sound but no picture


From this web site it says:
http://www.ehow.com/about_5379235_lg-television-problems.html
Powering Off
  • Many LG LCD television owners report having a problem with their televisions where the screen powers on, but then lasts only a few seconds or a few minutes before powering itself off again. The problem usually occurs with brand new televisions, and in this case is inside the television itself. If your television is powering off unexpectedly, contact LG so it can be serviced.

I've never have actually tried fixing these sets. Best Buy usually has the geek squad replace them with a LG product. If unplugging, and resetting doesn't work hopefully, they'll let you do the same. It has to have a service adjustment.

Sound but No Picture


Perhaps your remote is set to video recorder?  Try that first, and if no response, try calling up a menu on your TV and look for the Picture Settings.
Good Luck.
