I took the back panel off to check it out and i seen that 8 capacitors were bad on one of the circuit boards. Would that cause the problems that i am having?
Thats just normal take the tv to a tv shop and have those capacitors replaced and you should be fine

Hi, could be the main board but first you need to look for swollen capacitors on the power supply, here is the process:
, the solution to fixing your TV is most likely the power supply, if you are wanting to repair it yourself and can solder, it is most likely going to need (2) 1200 or 2200mf at 35volts electrolitic Capacitors, or you can replace the whole power supply. The back is held on with a few screws around the back and edge and then you need to pop the edges loose starting at the bottom side corners. once the back is removed the power supply is mounted inside a rectangle metal shield , remove the screws around it and the little ones going into the jack/input section (using a short philips there), there is a wire running from a circuit board to the USB input be careful not to pull on it, unplug its wire from the CBA. then look at the power supply (top center board) the cylinder looking capacitors that are bad will be bulged on top, usually there are two 2200mfd at 10 or 25volts. changing them should get it working. A repair shop will charge you around $250 for this job, FYI
hope this helps
thanks

SOURCE: Bad backlight inverter on 42" RCA LCD
Does the backllght go out after a few seconds? Could still be a lamp or something else on the inverter boards. You could try used inverter boards from the same set with other problems (broken screen), Or a complete working backlight from another set but very delicate operation to swap the LCD display from one panel to another.
