Lcd tv turns off after 5 mins, leave 2 mins comes on to stand by

No guarantees, but first unplug the unit (when it is on), wait 15 or so minutes, plug it back in and see if this recycling move will fix it. Also, check to make sure you haven't inadvertently set some kind of timer. Good luck . . .

Check and replace its main system memory IC.

replace capactors on mains power board they will have raised tops and look like little batteries with white kine on one side replace with same value e.g (2000.mf 25v) make sure line is on same side take picture to help

I think you are looking at a power board problem. I had the same thing happen to a Vizio and I replaced the power board and it solved the problem. It could also be the input board but most likely the power board.

Thanks,

Leave tv on and unplug it for 10 min. and plug back in should reset your tv.

I want to save you time and money here.
A new TV just like the one you have at Walmart cost $189.

A TV repair shop will most likely charge you $100 just to look at it. And the part, Backlight Inverter/Power Supply Board ( I believe that is broken ) will cost $110 min ( That's a used part).

It would definitely cost more than $210 to repair the broken TV vs buying a replacement 19" TV at Walmart for $189.

I would suspect overheating of an electric component in the power supply of the lamp (backlight) of your lcd tv. bring it in for repairs.
