Samsung UN60EH6050F has audio, dark blue screen

My Samsung UN60EH6050F is having a picture issue. I can hear the audio playing but all that is present is a very dark blue screen. I’m thinking either the backlight or T CON board from what I have read, but need more insight. It would not let me select my exact model the above tv is not mine.

Kristen Todd  shine a flashlight at an angle against the screen If you can make out shapes etc. it is your backlight. You can of course also remove the back from your TV and take a look at the small openings in the metal to your LCD. If the backlight comes on, it will shine through those openings. You can also disconnect the mainboard from the power board and then turn your TV on. It should come one with the backlight only (no sound/no picture). If it is the backlight you will have to do some voltage measuring on the power board as well as the LED connector. Let us know what you find and if you can post some images of your boards with your question. That way we can see what you see. 在已经存在的问题里加入图片

My backlights shine through the back. And I can't see anything with the flashlight just a dark very dark blue screen ( can tell its blue because it goes completely black when I turn it off)

So you can see the backlight turning on? If you backlight turns on then go ahead and measure the voltage on the T-con board fuse. You should get around 12V

Yes the backlight turns on when the tv is on. If the backlight isn't the problem it's more than likely the t con board correct? I will try to measure the voltage this week.

Kristen Todd I'd go with the T-con board then the main board....
