If you have the remote you should find a button labeled HOME. This button gets you into the menus. If you don't have the remote I believe the control buttons that are on the set are directly under the power-on led. They'll be very thin, possibly touch sensitive and difficult to see. You'll see a HOME lable there also. This acts the same as the home button on the remote.
Here's a link to the English user manual for your set, just in case you nee one....

Hope this lead you in the right dirrection.

    Here's a link to the service manual. Go to the download button in the middle of the page, not the one on top. It will make you wait a few minutes but will download a pdf. Please dont shoot the messanger. Your doing something I would try, and I know how it would turn out for me, bad.http://servicemanuals.pro/servicemanuals...

    have you tried. menu + menu then ok + ok to enter service menu?

  • Imed Ghenimi

    Neither the remote nor the tv have Menu or Ok, but instead they have Home and Enter.

    1. Press and hold your power button till the tv turns off - wait till you hear the back-light clicking sound. 2. Turn tv back on 3. Immediately press home>Go to Setup (hit enter)>Go to Options *** At this point do not press enter*** Press the FAV key 7 Times. 4. Expert TV Software Window will appear - try this with 42lv5400

  • Imed Ghenimi
    Imed Ghenimi May 11, 2014

    Do I have to use the remote or the TV board ? I tried both with no result. Just the fav key existe only on the remote control. Many thanks

No sound/picture on my LG TV


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
http://electro-medical.blogspot.com/

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Sevice menu


If you need to enter the service menu it is done with a special remote called a servicer's remote. Just press the INSTART button.

If you do not have one you can enter the menu by pressing the MENU button on the actual TV (or ENTER, OK) and at the same time press the MUTE button on the remote control.

Hope this helps, please rate my solution.
