Lag is where your HDTV screen takes time to cope with the commands of your wireless devices. 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. Fix this by clicking the ‘Menu’ button and go to the ‘Game Mode’ of your HDTV and adjust it from there. Then try to play with your gaming console again and see whether the lag improves.
There are many types of picture distortion that is evident in HDTVs. Some of these common problems are the following:
Mosquito – This is when the picture is filled with dots or noise. The main problem here is not your HDTV but the broadcasting. But if you want to correct this problem, it will cost you a lot. You will need to buy an outboard digital noise processor, like the Algolith Mosquito HDMI.
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. Also try to adjust the contrast, brightness, color, etc. for better picture.
Pixilated Picture – This is when the picture is breaking into pixels and turning into these horizontal stripes that continuously goes up. This is caused by low level digital signals that your HDTV is receiving, that are constantly dropping in and out. 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 I’ve listed above. So, if your HDTV has these problems; Crawling Moss, Burnt Edges, etc. where the pictures are unrecognizable. Or the edges of the objects in the picture tend to burst into bright colors. These cases are severe and you need to return your HDTV to the manufacturer and get your money back or let them fix this.
If the backlight in your LCD HDTV is too bright it can affect the picture. Therefore to correct this problem, go and click the ‘Menu’ option, then ‘Picture’ then ‘Backlight’ and adjust it from there until you get the desired brightness.
If your newly bought HDTV doesn’t turn on or the power supply isn’t 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. Here’s how;
First; open the casing, this might be intimidating at first, but taking your TV apart is fairly easy to do. Just don’t forget to remember where the screws go, so you can put it back after you’re done.
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; spot the bulging capacitor or capacitors and take that out with a soldering iron. Replace it with the same capacitor that you have taken out, but of course with a newer one, make sure they have the same serial number. And your HDTV would be as good as it was.
Having a professional mechanic to fix your damage HDTV can be very expensive and time consuming. You don’t need to be that skillful to fix certain problems; you can even see some tutorials on the internet on how to use a soldering iron if you don’t know how to use one. It’s as easy as this.
