Question about Televison & Video
Other than the power on-off button, the remote no longer seems to control the television. The menu does not show up. Further, the television control panel itself will not show a menu. We tried resetting the tv but that did nothing.

SOURCE: how to reset lg lcd tv
Whe you press the power button the TV led have to blink several times and the it have to change to blue, meaning Tv is on.
If you press the power button and the led start blinking and goes off, then you need to replace the mainboard because it is damaged.

Hi , I have the same problem with my LT-42X688,so i called the service of my extended warranty provider . the TV technician just left and told me the motherboard is the problem. he said its the third one this week he has seen with the same symptoms. he ordered the motherboard and i've got to wait 5 to 7 work days before the part will be in . I will keep you posted when the guy will return.

try unplugging while the TV is still on and plug it back after 5 mins and check. it should work.
Mine did. I know this may be a crude method, but it worked.

According to the manufacturer, to reset the entire unit do the following:
1. Press and hold "Menu" and "Channel +" on the TV. 2. Using other hand, press the power button. 3. A small screen should appear in the top left part of the screen. 4. Using the remote, select "Memory Recall" and select. 5. Power off and re-boot the computer 6. Run channel auto-scan to regain the picture.
