This sounds like a heat related problem, which could be a faulty chip or a cold (bad) solder joint on one of the PCBs (printed circuit boards). Due to the lethal voltages present inside a CRT type television, it is strongly advised to have this repaired by a qualified technician. however, if you or someone you know is technically inclined, you can try to fix this yourself. Cold solder joints can often be spotted by visible cracks in the solder joints. a through inspection of all the boards could easily identify the problem which can be resolved with a quick tap with a soldering iron and perhaps a little extra solder added to the joint. if that yields nothing, another method is heat/cold stressing the boards while the TV is running. With the TV on, spray small areas of the PCBs with cold spray (or a can of compressed air duster turned upside down) until the tv shuts off. then heat the last sprayed part with a hot air gun (or a hair dryer) until you can get the problem to repeat regularly. inspect the area causing the problem and you will probably find the culprit.

Assuming it is not hardware but soft settings...
1) Check and make sure that your TV does not have the timer set.
The Timer feature allows you to set a day and time for the TV to turn on automatically and the device and channel to display when it switches on. If the TV is already on at the requested time, the TV automatically tunes to the channel you designated in the Timer menu.
When the Timer turns on the TV, the following message is displayed: "Press a button for the TV to stay on." Press any button on the remote control within five minutes if you wish the TV to remain on.
Note: The TV clock must be set before you can use the
Timer feature (see preceding page to set the clock).
On/Off
Press down arrow / up arrow to enable or disable the Timer.
2) If not working, try SYSTEM RESET. Press SYSTEM RESET button on the front panel with pointed object (e.g. straight paperclip). TV turns off, green LED flashes for about 1 minute. When it stops flashing turn the TV on again. All settings other than Parental Lock need to be set again using the manual.
3) TV RESET. If all else fails for soft error. Your manual describes this last resort for soft type error. It could be hardware problem needing more expertise.

Could be loose connections on the board where the solder is expanding as it heats up causing a loose connection or something in the power supply or horizontal is over heating and your tv is going into shutdown protection . Good luck

Tv turns off after 15 minutes of use


For bobby11 and luis, it is the power supply. Part Number EAY34797001 in the 42" and EAY34796801 in the 32". This is a known problem, and somebody should start a Class Action against LG over this one. Part is available online and easy to swap out for anyone with the most basic knowledge.
