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.
If the screen is not broken but the screen does not come on but your warranty is no longer valid, here are some things you can do. One single part has probably failed in your flat screen TV. There are many circuit boards and wiring harnesses inside your flat panel TV. Some of the parts in an LCD or LED TV are power supplies, t-con boards, capacitors, inverters, controller boards, IR sensors, signal inputs, and more.
One of the best places to purchase TV replacement screens is on eBay. If you need parts like control circuit boards and wire harnesses, useful parts online has LED, LCD, and Plasma TV replacement parts at good prices.
Cheap TV replacement parts are available to fix your TV.
If you need a main board, T-CON, LED driver, or signal input board.
One of the parts may have failed in your TV therefore causing the screen to not turn on. Determining which part that may be bad inside your TV may be difficult. 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.
Have them tell you the part that has gone bad, pay them the $40 or so bucks it cost to troubleshoot, and go home and buy the part online yourself. This will save you money and your TV should work like new.
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.

We’ve just moved homes from the UK to Zurich. We moved our belongings by road including the TV. We have a SamsungUE55D800YU model. Since we set up home the TV screen is completely pixelated. With horizontal green lines. It’s 4 years old. Has been brilliant until now. It hasn’t fallen or has even a tiny scratch. Any advice would be appreciated.
I have an LG LCD. Light horizontal lines just started to appear. No damage visible, mounted to a wall closer to the ceiling. Happens more visibly when showing greens or blues, but seems to fade in and out. Can you tell me what the problem might be, and a possible solution. Thank you.
Tony,
May be as simple as a loose ribbon cable in the TV. If not, then it is most likely a board issue not the screen, if the screen rolls. It may be a power board that is on the fritz. Did you personally change the t-con board?

Camilia,
If the screen is cracked, it will need to be replaced to fix the colored lines.

I have a Samsung 48 smart TV it fell over and it shows a crack and colored lines. Way to fix my Samsung TV?
I have a Sanyo TV DP46849. When you turn it on you get a white screen with thin color vertical lines. You see some of the lines start getting lighter and lighter and then go white. There is no sound before this happened the right side of screen would roll like so i had the t-con replaced but no change. I spoke to a repair shop they say it may be a the main board just went out it powers up fine and the repair shop said the LCD screen was not cracked what do you think the problem may be.
Gail Patton,
If your TV has a blue screen and you see many lines, are the lines horizontal or vertical? What make and model is your TV?
