Here is another video showing a step-by-step procedure on how to fix a Samsung 52” LCD TV having some power issues, which I am seeing is one of the most common issues people encounter after a while of using their flat screens. This is actually a very similar to the Polaroid LCD TV problem I posted about a while back.
This problem is characterized by the failure of the unit to turn on. Trying it a number of times might eventually do it but if you leave it as is and not do anything to fix the problem, it may get worse and stop turning on altogether.
Like the Polaroid TV problem in my previous post, the problem can be traced to capacitors gone bad and the video will show you how to get to them safely and replace them using very simple tools, one of which is a soldering iron. Operative word here is “safely” so if you are in doubt whether you can do this due to safety concerns, I’d suggest you just bring it to a professional.
This fix can also be performed on other Samsung models in the same line like the LN46A750 46” LCD TV and will cost you just around $15. You will definitely get charged more than that if you have it done at a repair shop.
As usual, if you are interested to learn more about how to repair LCD TVs, I’d recommend checking out this LCD TV repair course by Kent Liew.
Below is the 2-part video of the repair:
