How to Diagnose TV Screen Problems

If your TV is not displaying properly, there could be uncountable problems in existence. This is a very simple issue to solve. On the other hand, it can be a complex complication that requires professional service. Before that, you need to do a diagnosis of the problem that may be beforehand before resulting to contacting a professional repairer.

Do not forget that there can be a simple problem that you can solve without a repairer and avoid using your money for no good reason. Even though the current LED TV price may be favorable, you don’t need to head that way! You can follow the steps below to diagnose issues to do with your screen and narrow down the problem

Step 1

Start with turning on your TV. If it does not turn on at all, you should first check the power cable to ensure that it is plugged into the socket. Furthermore, check the outlet to ensure that the outlet is working and has an electric charge. If one outlet is not working, the obvious thing is to try another one to see if that will work. When you are certain that the outlet is in good working condition and your TV still does not turn on, you may have a faulty power supply. This is a simple problem that can be solved by the repairman by replacing the power supply unit. If there is nothing to salvage, search for a retailer with the best LED TV price in the market.

Step 2

When the TV screen is having a blank blue or blank display, you can plug in an external device, such as DVD player, cable box or video game console. Ensure that you connect the video input correctly. If it is not displaying anything from the external source, this may be an indication that your video connection is faulty. This means that you should try fixing the video inputs properly or use a different video connection. For example, if you connect your LG DVD player via HDMI and it does not work, you can resort to using a yellow, white and red composite cable. You could be having a faulty video input while you take almost an hour whining that your screen is faulty.

Step 3

Check the bulb. When you are using an LCD projection or DLP TV and the TV turns on but nothing displays, the bulb might have burned out and needs to be replaced. You should take some time to consult your manual to determine where the bulb is located. Replacing the bulb is easy and you can do it yourself.

Step 4

Check the video settings if the screen colors are off or the picture is blurry, you can adjust them to the proper settings. This can be done through the TV’s video settings from the menu. Many TV models have preset r default settings that give you the best picture. However, you can adjust them to levels that will give you the best picture.


If all this fails, you can consult a repairer or the manufacturer if the warranty is still valid. If all this prove futile, just buy another set from CompareRaja who have the best TV deals.
