If this is an LCD tv the backlight inverter is bad, a good way to check it is to shine a flashlight close to the screen and see if you can see a faint picture.
Let me know what you find

You will have to isolate the main board and Inverters.
Unplug the inverters and turn on the set.
If it "turns on" then try re-connecting each inverter seperately to see if only one is causing the problem.

you need to check first the power supply board whether the output supply 12-24vdc for the inverter board is stable and not flactuating..you can measure the output voltage with a multitester..you get a voltage output of 12-24 with the inverter board is connected or loaded to the system.be carefull of the high voltage at the inverter board..once the output is stable replace the inverter board or you can measure the output of the inverter be very carefull..the output range upto 500vac.be carefull..if the high voltage is stable replace the lamps...tnx and good luck..

No this model is LED. I open back cover of a TV, then turn power on, hear sound, backlight does not on at all.
I try to unplug these cable from main board to T-cond board to check inverter board good or bad...light of a screen is on, show white screen, but as soon I connect these cable back to T-con board, a screen turn back to black (light of a screen totally turn off)
An LED tv dosn' have a traditional inverter board,
If possible post a picture of the tv internals
I am having a problem with the model#
