TV screen showing red and green lines through all images?

Question

My TV is a flatscreen DVD combi which is probably around 5 years old now. I've never had any issues with it although I accept the tv isn't brand new which means it may be breaking down.

I was watching TV today, and there was nothing wrong with it until about 30 mins ago. A very light amount of red and green lines were showing across the screen but the image was otherwise fine. I put on a DVD and the lines pretty much tripled; they moved around a lot.

I took the DVD out and went back to the TV, and the lines were still there. When I put the DVD back in, the lines are coming and going a lot.

I can still see the images pretty much as normal, so I don't need to go out and buy a new tv yet, but, I can't figure out what causes it - is it something I can fix myself, like just getting a new cable, or is it on a fast road to a recycling unit?

Answer 1

What you have is a convergence problem. That's a typical problem with sets that age. You're going to have to open your set if you want to fix that. I'm pasting some information from eHow on how to fix that problem. If you take it to a repair person it's probably going to cost like $150 to fix it.



Instructions

Power down your TV and disconnect the power cord from the wall outlet.



Open the front panel of your TV. There will be screws on the front cover of your TV that must be removed with a Phillips screwdriver. The screw locations can vary significantly depending upon model. There will usually be two to four screws aligned around the speaker grille of the TV that must be removed.



Pull off the speaker grille of the TV. This will free up the rest of the front cover.



Loosen the front cover of your TV by prying around the edges of the cover and creating separation from the back of the TV. The cover will still be connected by a set of cables, so do not pull off the cover altogether.



Loosen the twist ties holding the cables in place, then set the cover off to the side of the set.



Find the wood panel or cover that is now visible directly behind the removed cover. This shields you from accessing the internal components. It will have to be removed. Take out the screws along the face of the panel with your Phillips screwdriver, then remove the panel.



Find the small black box behind the panel that has a number of cables running into it. This black box should be found near the front of all the visible components, just behind where the panel used to reside. This box controls the voltage and convergence adjustments for the TV.



Focus on the bottom of the black voltage/convergence box. There are three large screws here. These screws control the blue, green and red colors of your TV, from left to right, respectively. Retrace lines on your TV will differ by color. If you are suffering from blue retrace lines, tighten the screw on the left with your Phillips screwdriver with a 1/8th rotation. Make this adjustment slowly and carefully. Green retrace lines can be fixed via the second screw, and red retrace lines via the final screw on the right.



Replace the wood panel, front cover and speaker grille of your TV.

1. When light falls on such a big thing as a movie screen, it does get diffused. But the real image is so big that small diffusion'sare not seen easily. However, nowadays, screens are selected to minimize this diffusion. 2. We can see our reflection on a mirror because a mirror reflects all the light which falls on it; hence all light from our face will be reflected and we can see the reflection. Also, the reflection is regular. Whereas a paper produces irregular reflections. And part of the light falling on it is absorbed. 3. Say, initially the truck was x metres behind the car mirror, and the image was also x metres from the car mirror on the opposite side. Then initial distance between object (truck) and its reflection is 2x metres. When the car reverses, it approaches the truck at a speed of 2m/s. After 1 sec, the distance between the mirror in the car and the truck becomes (x-2) metres. As the reflecting surface of the mirror is plane, hence the image of the truck will also be at a distance of (x-2) metres from the mirror, at the opposite side. Hence after the first second, the distance between the object and the image is (x-2)+ (x-2)= 2(x-2) metres, which was initially 2x metres. Thus the distance covered by the truck's image after 1 sec will be 2x- {2(x-2)}= 2x-2x+4= 4 metres. Hence speed of the image is distance/time= 4m/1sec= 4m/s.

Answer 5

better watch a movie,than read a written publication.Of course,it is simpler to get an improved picture by watching the action(images),then looking at each one of these portrayed words.

Television is merely educational if you're observing a documentary or something similar
