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.

How do I fix my Sharp tv model LC-42D62U? On the tv screen now shows horizontal lines with repeating ghost images.


Hi Paul,
The horizontal lines on the screen are virtually NEVER caused by a bad T-con board. These horizontal lines indicate a defective LCD panel (screen). The Screen has small ICs that become defective overtime and that it isn't fixable unless replacing the entire screen.

Hi I punched my 42" vizio LCD HDTV the screen


You cannot fix the screen. Your only option is to replace the screen. Replacement panel could range from $160-$230 range. If you cannot replace the screen yourself and take it to a shop to fix, the repair bill will cost more than a new set. May I ask your TV model # ?

Coloured lines on screen


Make sure first that the picture is centered by using the remote control to move the picture vertically and horizontally. Use the round pad towards the center of the remote and push the button according to which direction you want the frame to move.

Child accidentally let the Wii slip out and hit the screen of the Vizio Vol 32L. Screen is cracked and we only get lines- horizontal and vertical. Is it fixable?


Sorry to give you bad news, the screen isn't fixable.
The cost of replacing the screen cost just as much as a new TV.
The Wii controllers seem to be the number one killer for HDTVs. So far, your the 20th person that fell victim to this.
