I happen to have the same tv brand, size, and problem. The only difference is model. I bought mine black friday 2012 and its got screen problems. Im looking for a solution also to why it has the problem it has. It was working great for the time being until i noticed cloudy white spots around the perimeter edges. I found out its do to a few possibilities. One is the one thats wrong with mine that i believe is dead pixels. My tv doesn\'t look damaged in the screen butt when the image darkens while watching tv u can see it. Its like a bleeding discoloration. Me personally im taking mine back to either get my money back or new tv. From ur breaf description sounds like u have the same issue except yours came that way.if u look at my follows on here u will see pictures of my tv and the issue to my screen. I bought mine from best buy. So i got a thirty day store return warranty plus i purchased a 2 year warranty. So im going back and going to see what they are going to say. I advise u to probably do the same especially if u got warranty. As far as changing ur setting for HD picture quality with ur dish is to go through your menu options on the dish.i use comcast so mine is different butt im sure in a way the maybe might b in somewhat similar. With comcast theres a format button on the front of my box that i can press to change different format quality. If that dont give u what your looking for then see if you turn off your box while tv is on and then press menu on box and see if a user menu pops up if so then u should be able to change quality. You then can program it to be 1080 if ur using hdmi or components. One thing with comcast box is that i can make every channel 1080 bt the regular channels that dont broadcast that quality makes the picture smaller. So then u have to have HD channels to get 19080 quality. Butt u can get a good quality setting still with regular broadcast channels by overriding to 480p or to the best quality its puts out to that channel. Most broadcast channels set out a 480i or a a better HD 480p. Other than that you have to have HD channels and then ur box should automatically format to 1080u quality on the HD dish channels so you dont have to keep changing. Then when change ur channel back to standard broadcast channel it will automatically format to back to 480peither and so one as you change channels. Well hope it all helps and you got what you were looking for.
I'd guess that the surge damaged some resistors on the internal circuit board, possibly a capacitor. You may be lucky if this has an internal fuse, in which case the fuse may have blown, saving the main components. Best course of action is to take it to a TV repair shop or similar to have it checked out
Are you using it as a TV or monitor? If it's a monitor try it on another PC.
Does the same thing happen no matter what input you're using?
Is it overheating somehow?
Maybe try changing the sleep setting to 30 or 60 mins and see if there's any difference, in case there's a problem with that section. (Not that you can fix it if there is.)
Worst case scenario, the TV is faulty - if the backlight is actually going off, the picture would still be there but barely visible. But if you've just bought it there should be no problem about getting a replacement.
Sounds like the PC has too high a screen resolution set for the TV to handle Re-connect PC to PC monitor , change display resolution to 800 x 600 (right click desktop, properties, settings, slider marked "screen resolution" to leftmost side, save settings. connect PC to TV, TV should be able to display PC data now. Go through same procedure with PC connected to TV, move slider to 1024 x 768 posn. (depends on TV model as to what it can cope with) - *apply* this setting & see if TV is able to display at this resolution. If it is, desktop will appear - if not, you'll get the warning box generated by the TV...don't worry, in 15 secs, the PC will revert to the old (working) setting.
If your computer does not have a video card that supports the correct
resolutions for the widescreen monitors, then your picture may get
stretched. Much like watching normal tv programs on a an hd set. It
will eitther strech or cut off the picture.
Try different settings in you computer display settings.
You will need a TV Tuner expansion card for your computer. If you buy a TV Tuner expansion card and install it, and connect an antenna or cable TV cable, you will be able to watch TV shows on your computer monitor while using your computer. With some TV tuner cards, you can also record TV for watching it later, or even hook up your VCR and record VHS tapes and home videos to put on DVD. This is a more complicated topic and instructions should come with the TV Tuner expansion card you purchase.
TV tuner cards usually run in the range of $20-75 and will fit in most computers. You can buy them online and at computer or electronics stores. Installation is fairly simple and the instructions and software are included (unless you buy a used one)
