subject: How You Can Restore An High Ddefinition Tv [print this page] A harm High definition tv can be quite difficult. But before a person leap into conclusions and begin panicking, take the time to assess and look into these details because you can really do something about this.
Try testing the HDTV first before buying it.
But if certain problems and issues about your HDTV starts to materialize in the future, dont freak out and Im not saying that you should just relax, but some problems can be fixed and all you need, is a little know how.
Lag
Wireless devices that are connected to your HDTV takes a little bit more time for the screen to catch up and process the image or this is better known as Lag. This kind of problem usually occurs when using your gaming console. Lag is significant when using wireless gadgets, like; the controllers to your PS3 or XBOX360. You can press the Menu button and then press the Game Mode to correct this problem. Try playing again and see if there is any changes in the lag.
Picture Distortion
A damaged HDTV has many picture quality setbacks. Some of these common problems are the following:
Mosquito - This is when the picture is filled with dots or noise. Dont worry, there is nothing wrong with your HDTV set. The broadcasting is the problem. The way to repair this is by buying an outboard digital noise processor, such as an Algolith Mosquito HDMI. But this will cost you a lot.
Unnatural Colors - The tones and shades of colors in the picture is unrealistic. Fix this by choosing the Standard or Movie mode in your HDTV. Dont forget to adjust the color, contrast and brightness option for better picture quality.
Pixilated Picture - This happens if there are visible horizontal stripes that are continuously going up in your HDTV screen. This is because there is low digital signal that is coming in to your HDTV. Ask your cable provider to fix this problem or you can buy an inline amplifier/preamplifier to boost the signal strength.
There are also these types of picture distortion that is considered to be worse than those Ive listed above. So, if your HDTV has these problems; Crawling Moss, Burnt Edges, etc. where the pictures are unrecognizable. And having very bright outlines around the objects. These cases are severe and you need to return your HDTV to the manufacturer and get your money back or let them fix this.
Backlight Problem
All LCD HDTV has backlighting, either led or cold cathode backlighting. Backlight can alter the image in your HDTV. To adjust the brightness of the backlight, go to the Menu option and choose Picture then Backlight and start correcting the problem.
Power Supply
If your newly bought HDTV doesnt turn on or the power supply isnt properly working then I suggest that you return it immediately and have the manufacturer figure this out. But if your HDTV is quite old and is already out of warranty, you can actually fix this problem and will save you a lot of money. Heres how;
First; open the casing, this might be intimidating at first, but taking your TV apart is fairly easy to do. Just remember how you took it off piece after piece, so you wont find it difficult to put it back.
Second; the main problem with power supply is the capacitor. Find the capacitors, they are usually blue in color and are located at the right side.
Third; How do you spot the defected one? Find the capacitor with a ruptured casing or a bulging capacitor. Change it with a new, and it must be the same of a kind capacitor that you have taken out. Use a soldering iron to perform this task. And the power supply to your HDTV will be working just fine.
Having a professional mechanic to fix your damage HDTV can be very expensive and time consuming. And some problems are not that difficult to solve; all you need is well researched information to help you troubleshoot these problems.
