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:

Thank you!! This fix worked perfectly! on a Samsung 52″ LCD,The TV Was purchased March 2009!
All items to fix where purchased at RadioShack for $21.00! 4 (1000Mf / 35v) Caps the original caps where 16v! 35v works fine! 1 soldiering iron and 1 tube soldier! Thanks again!
Thank you so much for your video (and your helper too). You saved me lots of time and money. I wish there were more videos like this one on the web.
Thanks for the videos!! I watched your videos, went to Radio Shack and picked up the caps (my set had 4)1000mfd/10v and 2) 470uf/25v) I got the 1000’s for $1.79ea. and the 470’s for $1.49ea. Replaced them all, put it together and I am up and running!!! Super easy fix! Make sure your iron is hot like he says, otherwise you wont be able to melt the OEM solder.
IT Rocks buddy,
my TV is 46″ and the internal board look just little different than it shows in your video, but i can manage to get through it. i just spend 3$ on the capacitors and 8$ to get a solder.
Also i replace the 35v 1000nu CAP with (old) 25v 1000nu. As you said there is know issue in using higher value
Thanks a lot again for this video

Wowser! I have a Polaroid HD FLM-3732 with a set of bad caps, and the problem was just as you described. Today I am packing to move, and thought I would give this TV one last go around to tray and fix it before I took to the recycler.
Well guess what!? I came across your fix, went out to my garage and located some caps at 1000 uf/10v on an old Sun Enterprise 450 motherboard. A half hour later… Zikkity Clikk! The TV is up and running, and oh so beautiful.
The old caps were boiled and bulging, probably came from that company that used the electrolye formula that was stolen a few years ago.
Anyways, thanks for the point in the right direction!
loved your helper. i just threw away a tv with similar problem. never do that again. will keep this sight and others like it in mind. thanks. Greg in Missouri
