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.

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.

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.

I have a Vizio E470I-A0 and it was hit by lightning. I have replaced the power supply board and the unit now powers up with audio but I get what looks like Vertical color bars across the entire screen. Looks like a test pattern. I have two main boards and I get the same result from both of them.
My flat screen TV has had these weird vertical lines for the past week, so knowing how to get rid of them will make my TV watching experience more enjoyable. Determining whether the glass panel on my screen or the LCD or LED part of it is broken seems like something I should do right now. Both of those things seems really easy to fix.
Hadi,
It might be a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergnce select that and wait a minute the TV will adjust itself and give you a clear picture. If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the curser using TV remote and adjust each “point” so that each line is perfectly white. If you notice red or blue anywhere on that “line” then you have to adjust using the up, down, left and right arrow keys to “line up the red and blue lines with the nearest white line.

My TV Is RCA just got it a year ago and it shows green lines, and double image, and it turns blue when there is nothing connected to the TV.
BALA,
Is the complete screen showing the grey like flashing or just partial screen? Has something made hard contact with the screen or did this just start happening on its own?

I have a Toshiba LCD TV 32CV500E and have had it for around 4 yrs. Suddenly its showing light grey like flashing light.. still I can hear sound. What the issue and can someone advise ?
BRYAN,
The only way to fix this is to replace the complete screen since there are spider cracks in the corner. You can try finding a new 65″ LED screen here and SEARCH FOR YOUR RCA TV MODEL NUMBER or it may be more financially viable to replace the complete TV.

Diana S,
Can you see any actual cracks on the TV screen or is it purely color lines going vertical? If you see cracks the screen needs replaced. If you see vert lines only, it may be a component in your TV that was damaged. You could unplug, and open up the TV and check to be sure all boards look okay inside the TV. A component such as a capacitor may have been damaged when the toy hit the screen. You most likely have a bad screen but in some rare cases simply changing out a board or a cap on a board can fix this issue.

Less than 2 months after I purchased a new Sony Bravia 48″ 48R470 B LED HDTV a toy was thrown and bounced off the carpet and hit the TV screen. To the right side of the screen, there are vertical lines. It’s about 6″ wide. I can see a great picture on the rest of the screen. Is this repairable? Or worth repairing? It’s been sitting in my garage ever since. I purchased the TV in Sept 2015.
I have a 65″ RCA LCD LED backlight. While moving I must have put to much stress on it because it is now cracked in the top right corner with some spider Web action. Is this fixable and if so how would I go about it.
