To avoid giving the customer a wrong budget, the ideal would be to make sure that the screen or panel is not defective or to be the cause of the problem. For that we must do tests and measurements, which tests and measurements should we perform?

To check the backlight of the TV without disassembling, turn on the TV in the operating mode and use the flashlight to light the screen, if the image is being viewed, the backlight may be malfunctioning.
