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. 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.

My LG 42LV5500 TV SET suddenly developed problem. All dead, black screen, no sound just power light. All PS voltages are correct.


I would agree with you on that. But it is your money. If the TV is old then replace it, if it is fairly new give it a try.

Wired network is not set. Do you want to set wired network?


the tv should be plugged into a router, something that has a dhcp server. does your modem have a router built into it. without dhcp the smart function on the tv won't work. and that would take care that message, the tv just looking for internet access

HI, I HAVE SOUND BUT NO PICTURE


hi, if your tv has totally black screen the cause is either the inverter board get busted or the back light need replacement. if their is a white screen display but no picture, you must check the t-con board for screen panel display which have defective or burnt component parts .

Vertical black lines. But they are not solid. lg plasma 42pc3dv


This could be a poor connection with the LVDS cable which runs from the main video processing board to the screen, or a fault within the video processor on the main board. Worst case scenario is it could be a fault with the screen itself.
