You will get a white screen when you unplug the t-con from the main board. Doing so removes power to the LCD panel. Verify that all of your voltages from the power supply are correct. If they are, I'd look at the t-con board. It sounds like there is a problem with the t-con that is pulling down the main board.

SOURCE: White screen when I turn
The problem is that the t-con board is not receiving signal to the logic board or there is no supply coming to the t-con board. T-CON board gets the signal to logic board to produce image in to the screen if T-CON board fails white screen is produce. Try to check if there is a bulge up in the top of the capacitor. Note before opening the back cover of your tv be sure to unplug the unit feel free to send feed back good day and best regards.
