SOURCE: LCD TV SCREEN PROBLEM RED HORIZONTAL LINES OF DOTS ALL OVER SCREEN PLEASE HELP

I unplugged the TV and now the picture is back.I read that the LCD's are vunerable to static build up so unless my daughter is using her TV I unplug it.

I was thinking about getting a large LCD for the family room but I'm not going to until they improve on this technology.

Good luck to everyone!.

Cheers.

SOURCE: Vizio 42 in TV LCD HDTV white line across to of

That white line (usually jagged) is actuallly part of the transmitted picture. However, you are not intended to see it because it is located in what is known as the 5% overscan area. Your TVs today are more than just cable ready... they are a versital, technology filled multimedia display. You can see that line because the screen size or wide mode you are using is intended for 1080p/24 signals. You have 0% overscan with this screen size setting. This allows you to see ALL of the picture, including portions of the picture the broadcaster did not intend for you to see. You can change your screen size using the Wide feature in the Setup menu. See pg.62 of your user manual for details and descriptions of the various wide modes.

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.

Dark horizontal line


likely coming from main board which is involved in all signal---on screen display comes directly from a different area---4 years is about the life span of one of these sets---Google the model number with parts to see which boards it uses and what they sell for.

Blue horizontal and vertical lines


We have many problems with loose or poorly seated cables and connectors on these units. Pull the back and reseat all the internal cables, especially the LVDS cable to the LCD control bd. If this does not correct the problem the main cause is a bad LCD control bd. or possible a defective main bd.
