I bought a 46" Samsung HDTV (UN46EH500F) about 2 weeks ago and I was really satisfied about how great it is for the price I paid. But about 1 weeks ago while playing on my Playstation 3, I paused the game, went to get a drink, came back and the screen was black, as if it turned itself off. I turned it back on and everything was fine. A few days after I was playing Xbox 360 (different console this time) for about 3 hours straight and while playing GTA5 the screen turned itself off again! Actually it wasn't really off, the screen went black because when I press the "Power ON" button on my remote, it would turn it off and I had to press the "ON" button a 2nd time to turn it back on! Then the same thing happened again a few days ago while playing PS3, I was playing Killzone 3 and the screen went black again in the middle of a 1-2 hour game! This is when I started to panic... for a few seconds.
You see, I had overheating issues with my PS3 slim and a 24" 3D Sony TV over a year ago. My PS3 would get so hot and occasionally crash after several hours of gaming! I read on a Sony support forum that if I plugged the power cord with the white text facing upwards into my PS3 (http://i57.tinypic.com/33w2uls.jpg
), the positive and negatives would be connected correctly and it would resolve the issue. IT DID!!!!!!! Ever since I started plugging the power cord into my PS3 with the white text on the cable facing upwards, my PS3 slim isn't burning hot anymore and it hasn't crashed since!!! I did the same thing with my 24" 3D Sony TV by connecting the power cord with the white text facing up and it doesn't feel burning to the touch at all!
So guess what I did with my UN46EH500F. I plugged the power cord the other way!
It's been about 3 days now, I've been forcing myself to play long sessions of games and watching 2 to 3 hours of Netflix videos in a row and so far the TV didn't get any black screen issues! Also I don't know if it's just me, but I felt the back of the TV and it doesn't feel as hot anymore!
Could it be that plugging the power cord in your TV the wrong way could cause overheating? It did with my PS3 and 24" 3D TV! So maybe it's the same thing with these Samsung HDTV's!
If any of you are having overheating issues or your Samsung TV randomly shuts itself off, can you give this trick a try to see if it fixes the problem because I really want to know if this fixes the issue or not! Because if it does, someone needs to smack Samsung on the back of the head for not being more careful about this kinda thing! Plugging the power cable the wrong way on my PS3 nearly broke it! I don't want to repeat the same mistake on my $700 TV.
