Hello, I purchased my LG 42 LN 500 in 2013, and it won't turn on. The "on" switch on the tv is red, but when I press it nothing happens. Any DIY ideas? Thank you!

Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ If the remote control is found OK; check and replace the infra-red sensor inside the TV. Contact any service technician.

Stable red means that it's plugged to AC outlet but turned off. Try to use remote to turn it on. If that doesn't work, unplug it from outlet, wait for a minute then plug it back and watch for indicator - it can repeatedly blinks. Count how many times then google for code.

SOURCE: 42 inch LG Plasma TV - Lost picture

Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

My LG TV red light won't turn on. although the plug fuse and the remote OK


Try manually pressing the power/standby button on the tv (side or bottom) the red light should appear, most modern tv's will turn on simply by pressing the channel up or down on the tv itself.. But unfortunately in most cases, this seems to be an internal surge and needs a professional to inspect..

3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

Hello, I have a 42"


Sounds like a backlight is out. If its still under warranty, exchange it. First try unplugging it for two minutes to reset the t.v.

some times you have to turn it off, unplug it, wait for 20 secs and plug it in again and turn it on, this would be the last step after trying the remote control thing, you know, check if mute buttom or volume, or the languaje option, good luck, God bless

When power button is pressed on the remote or TV. Nothing happens. Does not power on.


Same thing using the power button on the TV.
Try unplugging it for about an hour to let it reset itself, if still does not work, then you will have to take it apart.

I have an LG 42lg30 and the user manual does not show you how to program other divices remote codes so the LG remote controls my cable box and dvd player. Does anyone know how this remote works?


go and buy a universal learning remote and you will be able to program all your devices on the remote, works very nice. as far as the lg remote, dont think there is a way where u can program your cable and dvd onto the remote and I have lots of experiences with LG
