How to Fix a Tv Screen With Lines

Things You’ll Need:

  • A flathead screwdriver
  • An electrical tape
  • An LCD TV screen replacement
  • A small Phillips screwdriver
  • A plastic card

Directions: How to Fix a Tv Screen With Lines

Step One: Disconnect The Plug

Open the Tv cabinet and find the power cord. Disconnect it from the back of your TV by using a flathead screwdriver to pry open the plug casing on one side and then pull away gently. Take note that you will probably have to use a lot of force to get the plug out.

Step Two: Locate The Screw

Locate the three or four screws on each side holding your Tv cabinet together and use a Phillips head screwdriver to unscrew them. Take note that you will need to remove all of these to come off for the TV cabinet.

Screws on Each Side Unscrew Them

After you have taken out the screws, check if there are any cables attached to the back of your TV. If so, remove them. Please do this by pulling it off gently to aside. The one with the wires connected would be the video cable, and another one is the power cable. Once you have it all the way off, pull the TV cabinet away from the wall and then, lay it on the ground.

Step Three: Remove the Cabinet

Remove the cabinet carefully and set it on a flat surface in your home, preferably an area where you are not going to be moving around much as there might be some cables that need disconnecting. Use a Phillips head screwdriver again to unscrew any visible screws or bolts so that everything inside is loose enough that you can take it off the TV screen.

Use a Wrench

Step Four: Disconnect Cables

Disconnect any cables found on your Tv cabinet that connect to the back of your television so as not to leave them dangling and disconnected when you put everything back together. These might include a cable for power, HDMI, or an antennae connection if they exist in your TV set-up.

Step Five: Lay Your TV Cabinet Back

Lay your TV cabinet back on the Tv screen so that it is facing up and open as if you were going to put more things in it. Use a small Phillips head screwdriver or an Allen wrench (depending on what type of screws are used) to remove all visible screws or bolts from the front of the TV cabinet, and be careful not to let anything fall out of place.

Step Six: Remove Your TV Screen

Remove your Tv screen from the television set-up so that you are left with just a bare board in front of you where all the circuitry is located. Be sure to remove any cables or wires connecting to it as well while still being mindful about not letting anything fall out of place.

Step Seven: Use a Screwdriver to Remove the Screws

With your Tv screen face-down, use a Phillips head screwdriver to remove the screws from each side and then carefully turn it over so that you are now facing up with all the circuitry in front of you exposed. If there is any visible dust or dirt on this area, be sure to remove it with a damp cloth before proceeding.

Step Eight: Use a Small Flathead Screwdriver

Use a small flathead screwdriver or any other long, thin object and gently push the circuit board back into place if you see that it has fallen out of position. Do not force this in order to avoid damaging anything else within your TV set-up.

Step Nine: Checking for Any Lines on-screen

Once the circuit board is back into place, use the Phillips head screwdriver to put the screws in. You should now be able to turn your TV on and confirm that it has been fixed successfully by checking for any lines or artifacts showing up on-screen.

Step Ten: Place the Circuit Board Correctly

If there are still lines or artifacts, you will want to repeat the steps above until they have been resolved. The most common reason for this is that the circuit board was not pushed back in place correctly.

Step Eleven: Place Screws and Other Small Objects

Once all of the issues with your TV screen have been fixed, be sure to return any screws and other small objects to their original location. Since you have already had your hands on the interior of your TV, dust will have collected inside. It is important to remove any dust that has entered your television so that it does not build up and begin to interfere with its operation.

Remove Dust From Television

Once you have finished cleaning your TV, put everything back together, reattach all of the cables, and turn it on.

Step Twelve: Before Plug in Check All the Issues

Finally, before you plug in your TV and turn it on for the first time after fixing it, be sure that there are no visible cracks or other issues with any of its surfaces. If there is any visible dust or dirt on this area, be sure to remove it with a damp cloth before proceeding.

Reasons Why Tv Screen has Vertical Lines and There Solutions:

1) Old Tv Without a Digital Tuner:

If you have an old analog TV, it may be showing vertical lines because the TV is not picking up any digital signals. To fix this problem, get a new digital converter box or go to your local electronics store and purchase an adapter that will convert from analog to digital (this will allow you to connect your old TV and watch digital signals).

2) Old Tv With a Digital Tuner:

If you have an analog TV but with a digital tuner (wireless or cable), the problem may be that it is not picking up any channels. To fix this issue, try moving the antenna around until you find a spot where it is picking up the signal. If you are using a cable, try unplugging it and plugging it back in to make sure that the wire is plugged into both ends securely.

3) Power Cord Is Loose:

If you are still experiencing lines on your screen, it may be because the power cord is not securely plugged in.

To fix this issue, try plugging it into an alternate outlet or surge protector and see if that works for you. If that is not the problem, the cord may be damaged and in need of replacement.

4) Broken Screen:

You may have broken your TV screen if there are horizontal lines or black bars on one side of the screen. This means that there is a loose connection on that side. Try to reconnect the wires and see if that fixes the problem.

5) TV Is on the Fritz:

If you are still experiencing lines, it may be because your TV requires service. Contact a qualified technician to come out and check things for you or buy another TV altogether if there is nothing that can be done to fix this problem.
