How to Activate the USB (For Service Only) of your LG LF20 LCD TV

By Edited Mar 11, 2016 1 13

Ever wanted to use your LG LCD TV's USB (for service only) to watch DivX format movies (mp4, mpeg, avi, vob, etc.), play music (mp3, wma, etc.) and view pictures (jpg, bnf, etc.) without ever using an external DVD/HDMI/Bluray. With this new feature, your LCD is now at par with the new model of Samsung (Series 6), LG (Scarlet), and Bravia with relatively lower cost of the unit. Please read below for detailed instruction:

Things You Will Need

1. You need an LG LCD TV(LF20, LH20, LH50, etc.) and an active USB thumbdrive loaded with multimedia (pics, movies, mp3, etc.)

2. Insert the USB thumbdrive at the back of the LCD unit, make sure not to remove it during the entire process else this could cause your USB drive to be corrupted.

3. Go to the service menu of the LCD TV (not the typical function menu) by pressing and holding the menu button for 5 secs waiting for the menu display to disappear. Afterwhich, press and hold the menu button at the side of the LCD simultaneously.
Wait for 5 - 10 secs until the service menu code would be prompted. Enter 0-0-0-0 (zero-zero-zero-zero) in the code panel and the display will show the service menu.

4. In the service menu, you will see various options, goto tool options 2 and click enter. Afterwhich, goto the USB and change the number from 0 (zero)/OFF to 1(one)/ON.

5. After changing, press return or menu to exit the service menu.

6. Press the menu button to go to the function menu and you will see that the input tab is already replaced by the USB tab.

7. Open the USB tab and you will able to play your favorite movie, pic, music.

8. Enjoy.

Nenad, no idea if it will work on your model. Tried that method on mine but failed. I cannot get to see which version it is with now.

Hope geeks around the globe would be able to hack into it to get it activated.

I bought a LG 26LG4000 TV at the weekend and discovered that the USB at the back was service only - would the hack above work on this model or am I at risk of bricking my TV? I could always take it back I suppose!

I bought a plasma TV LG 60PK250; the above procedure to activate the USB port (service only) could be valid for this model also ?

Crisostomo,
Thank you soooo much, dude. Really! On this side of the pond, the asshats who sell LG have no clue what they're talking about. When I called them (about 4 years ago) to ask about using the USB port, they told me it was there "for aesthetic purposes" and couldn't be used. I didn't want to spend any money "fixing" the problem, so I forgot about it. When my DVD player broke, I started trolling websites that could possibly help me. Thne I found you. THANKS
