Hi,

First make sure to hit the menu button on the TV's remote and if nothing is there then friend while the set is on turn a bright flashlight on and shine at angle into the set push the TV menu button if you can see a image then your backlight is not working.You can also check the transformers they are close to were the wires plug into the panel, make sure all transformers read the same amount of resistance if not you have found a bad one. Now you will have to check to see if the power supply is sending 24v to the backlight, if not the power supply is bad. Cost backlights around $150 and power supplies around $100.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

No picture, only sound on LG 47LV5500: how do I get picture back?


Definitely odd for sound to come through and not sound, especially via an HDMI connection.

I would contact LG for support, your TV could be defective.

Good luck
