If checking the capacitors does not reveal any rounded caps and all the capacitors look ok then the problem could be the back light. I am not a repair specialist but i get tv's and monitors from ppl that arent working and make a hobby of fixing them. The first thing I try on screens that have gone out is adjusting the brightness. if the screen is dark but a picture is still displayed the backlight is failing. To fix this turn the brightness all the way down and the backlight may not require as much power so it does work in cases of both backlight failure and low capacitance issues. also a repair shop will have a test kit to test the power flow through different parts of the circitry system to find faulty components.

First of all check out the tv power cord wire is it fine or seems like it got cut from some where or do you get any burning small from the wire.if this the case then repair that wire.if the wire is proper then try that wire in another electric outlet.if everything does not works.then is naturaLLY the internal board error.any of the capacitors or the ICs have gone short .the faulty 1 should be checked and replaced.
