If you are not afraid of taking the tv apart you can check the connections of the ribbon cables and check to see if you have any swollen capacitors. If these look good your control board may be going out.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
