If you have a broken LCD LED TV Screen that has any type of damage such as lines running vertically, spots or patches, cracks or breaks, this page will give you tips to get it fixed. Many TV’s nowadays (Plasma, LCD, LED) are large and delicate.

If a large flat screen TV is not attached to a wall, it has a higher chance of falling over and cracking the screen. If your flat screen LCD TV has fallen over, most likely the screen has taken a hit. See below for some ways to possibly fix this without having to buy a NEW TV.

If your TV does not have a cracked screen and the problem has just appeared on its own, you may be able to fall back on the TV manufacturers warranty. If your TV screen has developed spots, vertical lines, small dots, unusually bright pixels, fading, distorted shading, or color issues, you may be able to use the warranty.

To make contacting your TV manufacturer easier, we have included links to most TV manufacturers below. Be sure to have your purchase receipt, and take note of the model number and serial number on the back of your TV.

TV brand links for warranty claims listed by popularity: Samsung, Vizio, LG, Sony, Sharp, Panasonic, Insignia, Toshiba, JVC, Philips, Magnavox, Sanyo, and Emerson. These links will help you to contact the manufacturer to file a warranty claim. If the TV has a been cracked or a hit to the screen has caused colorful vertical lines, then this is something that has happened from physical damage and is not covered under warranty.

If your flat screen TV has the dreaded vertical lines, half of the screen has turned darker, the screen is cracked, or the screen is broken, this can be repaired but may cost more than you paid for the complete TV. If your screen is cracked or broken, you can try replacing the Screen, LCD, Plasma, or LED part. On some flat screen TVs there is a glass panel on top of the actual screen. You need to determine which is broken before you attempt to order parts.

Repairing a Broken Flat Screen TV
If you are going to be repairing a flat screen TV there are certain problems you may encounter. The most likely issues on broken TV’s will be a cracked screen, picture lines or black spots, or image distortion problems. If the damage to the screen has NOT gone past the screen, and has NOT gone into the LCD, LED, or Plasma behind the screen, then fixing the flat screen TV is going to be possible if you get the parts you need cheap.

If your TV screen is severely cracked and the damage has penetrated beyond that, then it is deep enough to have damaged the LCD, LED or Plasma. If this is your case, then it may cost more to repair your TV than to replace it.

There may be some LCD LED PLASMA TV repair shops near you that can answer some questions for you. Some flat screen repair shops do not repair broken screens as the cost is not worth it. They will however replace different internal parts in the TV that may have failed. These failed parts in the TV may have caused the TV to not display the screen correctly, ghosting, or a screen that is not turning on.

It can be done but is not recommended if you have no knowledge of using a multimeter or have no electronic repair experience. However if this is your situation, you can take the TV to a repair shop and they can troubleshoot the issue for you.

If your TV is NOT fixable, most people take out the circuit boards and part them out. Selling the audio and video components in your broken TV may be the only way to try and recoup the cost of the value of your TV. This is not recommended as some used TV parts are not worth very much. If you do decide to remove the parts, you could try selling them on eBay.

  1. My TV has a blue screen, with a crack and with a lot of lines. The screen itself is not cracked. How do I fix it and what part is it.

    John,
    If there is no sound and the screen won’t power on, you may have a power supply board issue. Was the screen struck or hit before this problem appeared?

    Kim,
    The inner screen is what is probably causing the lines. They range in different prices depending on where you buy it. A good place to look would be eBay for a replacement screen. May be better off just buying a new TV.

    John,
    Yes we agree, it is a shame to throw away a giant TV that has one bad component. We always try to tell people to fix it themselves by using used spare parts to keep cost down. Try to find the same TV online for parts. Many times we have fixed a TV by simply finding the same exact TV online on a website such as Craigslist. We had a t-con board go out on a 55″ Samsung TV. We found the same TV with a cracked screen online for $50 dollars. We bought it, removed the board, and put it in our other TV and it fixed the problem. We now also have other spare parts, a new remote control, and another TV stand in case we ever need it. If you have the money, buy new, if you don’t have the money, get creative and try to fix it yourself.

  5. Its well out of warranty….so I’m on my own with this….is there a quick fix ?….is it economical to repair ?…seems a shame to trash it ?

    John,
    May be a thermal heat defect issue. Check the warranty and call the TV manufacturer and you may be able to claim it is a thermal heat issue that has caused the screen to malfunction.
