With the importance of home entertainment in modern society, many people are choosing to invest in a flat screen TV,, which offers many benefits over preceding types of television sets, like the old CRTV TVs. However, these newer, classier-looking flat screen TVs often come at a hefty cost, making it even scarier when your TV stops working. Fortunately, troubleshooting and fixing flat screen TV problems is much easier than you might think. Sure, the repairs may still require a nice chunk of change, or may even require the help of a professional, but it is better than buying a new flat screen TV.
Repairing a Flat Screen TV
When it comes to repairing a flat screen TV, there is a wide range of issues that can cause problems. The most common problems people seem to have are screen and picture-related. As long as whatever damage to the screen has not penetrated the layer of plasma or LCD pixels behind the screen, repairing the flat screen TV is possible. If the damage is too deep, it may be necessary to replace the TV altogether.

Scratched Screen
For a scratched screen, varying methods for fixing the TV are available. This includes using a scratch kit, auto rubbing compound and clear lacquer, or petroleum jelly.

Keep in mind that the third method is a temporary fix, but it does involve less risk.

Cracked Screen
For small cracks, you can use the above-mentioned petroleum jelly method. First, clean the surface of the area of the screen surrounding the crack with a rag dipped in diluted isopropyl alcohol. Then, apply a generous amount of petroleum jelly to the cracked area of the screen using a clean eyeglass cloth. Be sure to smooth out the jelly, as well as to remove any excess jelly from the screen.

The petroleum works well as a quick, easy, and affordable fix, but it is not a permanent fix, and generally only works with small cracks that are not easily visible. For large cracks, or cracks in the main focal points of the screen, you are likely better off replacing the screen completely.

Broken Screen
For those who have a broken screen, there are three options: get a new TV, replace the screen yourself, or have a professional do it.

If you are going to be replacing it, start by locating the frame screws and work at unscrewing all of them. Remove the frame from the TV and set it aside. The next step requires you to disconnect any cables connecting the frame and the screen. Be sure to take note of which wires go where. After removing the broken screen, put the new screen in place, and trace your steps back, plugging in the wires, re-assembling the frame, and securing the frame with the screws.

Screen Distortion
A common problem with flat screen TVs, plasma TVs in particular, is screen distortion, which includes issues such as dead pixels and screen burn. There are many different solutions, but one cost-effective method requires an external DVD player (even if the TV has a built-in DVD player) and a pixel corrector DVD.

Start by disconnecting all devices from the TV except the DVD player. Use the TV’s menu to navigate to the resolution selection screen, and choose the highest resolution supported by the TV. Insert the pixel corrector DVD into the DVD player and choose the repair function you need, or use the software wizard to guide you through the process.
How to Buy Flat Screen TV Replacement Parts
Whether you are looking for a new flat screen, circuit board, or other flat screen TV parts, a reputable place to find parts for many TV models at a fair price is eBay. Simply enter the keywords “flat screen TV replacement parts” into the search bar for a list of available items. You can further refine your search by entering more specific keywords.

As flat screen TVs are typically quite pricey, they can cause a huge headache when they break. If you’ve thrown your Wii remote at the TV during a vigorous round of Wii Sports, have no fear; fixing your flat screen TV may be much easier than you thought.
