Hi I have a 37" lcd tv with a problem. It has a line from left to right...a bit of a hazy line. It works its way from the bottom to the top...then starts again. Tried another tv on the arial to see if it was that and the other tv is fine. Its not TOO bad on a brightly coloured pic (but still visible) but worse on a dark background. Can you HELP !!!

I agree with tvtek, problem is cable lead to set. If you use a line amplifier and it is going bad over over gaining signal, this could be the problem. Replace your cable. Multiple pieces of equipment attached to line inputs can cause a ground loop and produce same problem. Use a true line conditioner, such as a UPS for a computer to filter the AC and hook all the equipment going to set to it.

It sound as if you have a grounding problem with your antenna system. The lines sound like A.C. leakage getting through to the TV. If there is a way to connect another antenna to the TV try that and see if the lines dissapear. If they do then there is your problem, that antenna lead.

We have a 3 year old olevia television. the other day, a horizontal line appeared on the screen. it is in the middle and goes from the left side to the right side about three quarters of the way. what can...

I'm sorry but nothing can be done to fix the problem because it is defect of lcd panel (screen) that will be replaced but it would cost you approx new tv price so new tv is better choice instead of lcd panel replacement in this tv.
Again, I feel sorry for the bad news.

Small green line on right side of screen

This is an easy fix using the Philips remote control that came with your tv. On the center of the remote is a dial that has left right up down controls. Stand in front of the tv and using those controls you can recenter the screen and get rid fo the green line. I had same problem when we hooked up hd satellite reciver to philips 37 plasma

Hi my name is Roety,
I can help you with your issue ,

 If the line is present on all inputs, and shows in the menu then that means the panel is bad, The panel is the front screen section. A new panel would cost more than a new TV

Red vertical line down right side of the screen


I think your TV have a trouble inside lcd panel
the controller board contains driver IC. Deffective driver IC can cause of line display.

Three reasons why one vertical line accross screen can happen in LCD;

1.The missing signal from the controller IC to
LCD driver.
2. LCD driver IC itself defective
3. Dry contact in the tape carrier package.

Use masking or electrical tape to mark it where the line was located. press it if the line back to normal but when release your hand came back i think it was intermittent. Open the LCD panel

Use robber
Place the rubber on the top of TCP
Gently close back the top casing

Good luck...

Press the menu button on the LG remote. If you see the line affecting the menu, then the LCD panel needs to be replaced. If not then you have a signal issue.

Toshiba LCD 37" with gray band and blue line

Unfortunately you are right it is the display panel going bad. You can either live with it or buy you a new tv as the panels usually cost as much or more than the tv. Sorry.

Faint Black Line down the middle of TV

Sounds like it could be pixel problems or board problems, this depend on the location. Most are mostly to the left or right, or going across the set to the upper or more to the lower side. For more info visit
