You either have the power supply module or back lights inverter board problem, need to narrow it down.
Please see my basic troubleshooting guide here:

Hello,

Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.

if otherwise the power supply board is faulty you can try websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Hope this helps
