LCD TV Repair Review Power Supply Overview-No Power Common Power Supply Repair & LCD TV Power Supply

I would like to say that if you are having a problem with your TV be sure to check the model number first. The model number appears in this little box over here. Every TV is different, this is a Sony LCD TV but you will see the model number and serial number over in a box like this. The model number are very important because that is what will help you to identify what parts are needed to repair your TV. If you are having a problem with your TV, please feel free to comment in the comments section below this video or send us a message on YouTube with your TV model number and the problem that you are having. This way we will be able to help you diagnose the problem and suggest a fix. So the first thing you are going to want to do is make sure you have unplugged your TV from any power source and that you have also grounded yourself properly. Next you will want to take out the screws in the TV that are holding the back cover on it. Every back cover of at TV is different but most are help in by screws and can be easily removed. So we have removed all of the screws here on the back of the TV, now we are just going to remove this back panel. One thing to consider is that not every TV is going to be the exact same. So not every TV will just have these four main parts some may have more and it may have less. Some of the parts might be connected, where you might have backlight inverters and power supplies on the same board. There are typically two different levels of repair for TV parts. You can open up your TV, find the board number and then look up that board number to find a replacement part or you can take your board and try and repair it at the component level. At the component level you would be testing different components on the board and making sure that they work. The first board we are going to look closer is the power supply. Now the power supply again, takes in power and distributes it throughout the TV. So the first thing that could go wrong here is that the TV set will not turn on. If you are not able to power on your TV the first thing I would do is double check that the outlet works. Try plugging something else into that outlet and be sure that it turns on. You could plug in a clock, you could plug in anything, but just be sure that the outlet works before you start taking your TV apart. If the outlet works and you are still not getting power to your TV, then you will want to take a look at the power supply. Power supplies will have a fuse on them. You can check the fuse to see if it is blown and if it is you can try replacing that and plug the TV back in. If the TV powers on and the fuse stays good, you should be set to go. If the fuse blows immediately after plugging the TV back in then you will have another issue on the board that is blowing that fuse. If you are going to try and check you fuse on your power supply, sometimes it can be a little bit more difficult. Some fuses are ceramic and you would need a meter to test that fuse to see if it is bad. Some common things to look for on these boards are blown capacitors, where you will have a capacitor like this that has become raised at the top or is leaking fluid. Again, just a reminder that if you have any issues with your TV and you can't quite figure out the problem, feel free to comment below this video in the comment section and try and be sure to include your TV model number, possibly the serial number and any symptoms or problems that your TV is displaying.
