 Now a days, the price of fixing a tv can cost just as much as buying a new one people say. Well, that really isn't always the case. Today, I will teach you a few tips to know if it is even worth calling a repair center for your tv.
The most expensive part of a tv, is what we technicians refer to as the grid, or the panel. This grid/panel, is the actual screen that you see where all the pixels are located. This is not to be confused with the thin layer of plastic covering it. Many people confuse the thin layer of plastic protecting their panel as the panel itself. If the panel breaks, cracks, or gets water damaged, then you are looking to spend more on the repair than you spent on your tv almost every time.The reason for that, is because the cost of the part is extremely high, and can range anywhere between $500 for 42" tvs all the way up to $1500 for bigger 50" to 60" tvs. Now how do you know if your grid needs to be replaced? Sometimes it isn't always obvious that the screen is cracked, however a sure way to know is to turn the tv on, and look at the image. If the image on the screen looks anything like the picture to the left, then you know your screen is cracked even though when turned off, it may look perfectly normal. Water damage: This will occur often when people are trying to clean the tv. If you are trying to clean your tv with some sort of solution, never spray it on the tv itself, and here is why. When someone tells you not to spray the tv itself, it is not because spraying the tv will harm it, after all you are really spraying a piece of plastic. We say this because of what happens after you spray the tv. The solution will start dripping down the screen, and once it reaches the bottom, it will start to go inside the tv. At the bottom and the top of every tv there are several electric boards which we call buffer boards. These boards are directly attached to the panel/grid of your tv, and are not detachable. If one of these boards gets damaged, you will need to replace the entire panel. For other issues you may be having with your tv, please go to the repair service page, and see if your the issue you are having with your tv matches our list of symptoms we commonly fix. If you find your issue listed there, then your tv is most likely experiencing an internal issue, and can be fixed at a reasonable price.

More and more often you will find that your TV will stop working properly after a few years of use. Sometimes it will only last a year, and sometimes you can go 10 years before something happens. This is partially due to the fact that we are using newer technology, with a lot of different functions, and options we did not use to have. Smart tv’s, 120HZ smooth motion and other options are now available, and can cause firmware malfunctions. Just like a computer, newer tv’s can benefit from a system reset even if it does not have internet or 120HZ capabilities. Here are some symptoms a basic reset can fix:
The idea behind a system reset, is to deprive the tv of all electricity it may store. This will allow your smart IC chips, on your internal circuit boards to reset. A system reset will only fix software/firmware issues, if there is physical damage, such as bad components or shorted electric lines inside the tv, this reset will not fix your issue. Some TV’s, especially Plasma TV’s can store lots of electricity with very high voltage for several hours after being unplugged. Power supply boards along with other boards inside your tv can have very large capacitors that store all of this electricity which is meant to speed up the process of turning your tv on. In order to perform a reset on your tv, you must unplug the power cable where it meets with the tv. If for some reason your tv’s power cable is hardwired to the tv, then you can unplug the cable out of your wall, or power strip/surge protector. Once you have done that, you must keep your tv unplugged for at least 4 hours if you have an LCD or LED TV. For a plasma TV, you will want to leave it unplugged for up to 8 hours. After keeping your tv unplugged for the durations listed prior, your TV will be deprived of most or all of its electric residue. In order to make sure that there isn't any electricity left in some of those larger capacitors, you will want to press the power button on the side panel of your tv for 30 seconds. You must press the power button on the tv itself, and not on the remote. By doing this, you will trick the tv into trying to turn on, which will take out any residual voltage out of the capacitors. Once you have performed the above test, you may plug your tv back in. I would recommend waiting at least 10 seconds after plugging the tv back in before trying to turn it on again. This will allow the tv time to charge its capacitors back up. If performing this reset doesn't fix your issue, this means that you may not have a software/firmware issue, and that you will need to bring your tv into a technician for diagnostic. |
