model un50eh6000fxza tv will play for many days. do not have meter.is this power board or main board issue
Hi @mwbledsoe , Is there still audio when the picture disappears? With the TV on, when the picture disappears shine a torch at an angle close to the screen to check if there are still images there or not. They will be very faint so try it in a darkened room to help see them if they are there at all. This is to determine if it is just a backlight problem or something more. If it is just a backlight problem, without a voltmeter it will be difficult to know whether the problem is in the power board, the backlights or perhaps the mainboard. Switch off the TV, disconnect the power from the TV and then remove the back cover from the TV and visually inspect the boards, especially the power board, for any obvious problems, such as heat stressed components or blown or bulging capacitors. If you spot something and are not quite sure, post some close up images back here. Here’s how to do this on ifixit. Adding images to an existing question
