TV turning off my itself after a couple minutes.Was told to replace the main board.Replaced the main board and tv played perfect for 1 month.Now it is cutting off my itself again.Whats going on?

Hi Johnny,
Please take out the main board, keep it immersed in mild liquid detergent solution for some hours, rub it thoroughly with a tooth brush, wash it with clean warm water, dry it thoroughly with hair drier and fit it back. Hope it works. It has done the trick for me several times.
Good luck.

You have to buy its main power regulator board as card basis. Normally, repair to these boards are almost not possible. There should be a number printed on the board, and you have to buy the exact replacement board only. If you wish to get some more details about the power board replacement to LCD TVs, check this link.
Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.

Samsung UN46D7000 red light blinking and clicking

I have this exact same model "UN46D7000LFXZA" with the exact same problem and I also replaced the power board expecting that since that is where the clicking was coming from that would fix it even though there were no swollen capaciters. However, it didn't and the board is from a working pull so I knew that was not the issue. What I did is I unhooked the main board connection from the power board and turned it on to test a hunch, and instantly the LEDs powered on and no more clicking. I just received a main board in the mail switched it out a few minutes ago to confirm it was indeed a main board problem. I got mine for $114.99 on eBay after confirming that the part numbers that were slightly different were interchangable. I lost all of the firmware upgrades changing out the main board obviously but downloading and installing those is a small price to pay for finally having a working 3D TV back for less than the cost of the extended warranty.
I would suggest carefully trying the same thing and disconnecting your main board and make sure your LEDs light up. I bet they will. I was just guessing at the main board but since there are only two boards left after the power board was replaced and the other board should have no affect on the power board to my knowledge I think this will fix your issue too.

Philips 42PF9956/37 Plasma TV - Looking for y sustain board

it isnt the Y-SUS board, it is the Power supply, iv fixed this exact problem twice in the last month, try turning the tv on, and when it turns green, unplug it real fast, while light is still green, after 15 seconds plug it back in, then hit the power button, if it dont come on, hit the power button again, this time, as soon as it turns off, hit the power button again to turn back on, sometimes you can trick the tv and it will turn on, at least i was able to do it, and once it comes on, it should work fine, untill you turn it off again.

No screen display - VIzio 50" Flat screen TV

If you purchased the TV 6 months ago, still under manufacturers warranty. They normally give customers 1 year warranty coverage.
It looks like the main board will have to be replace on this TV or fix to the component level.
