Friend this is a very common problem with LCD and also DLP within the power supply the capacitors (you will have to check the board that has the power cable going to it.)
Start to fail and the way you can tell is to check them visually for swelling or expanding of the top.
It will be easy to see the bad caps will not be as flat on the top as the good ones, But also you can have a bad resistor or diode and even a bad regulator. And this is the problem,
Exchange them and you will be ok, Good luck friend, and if my efforts are appreciated, feedback and or bonus will be appreciated
