Samsung TV Model #UN46EH5000FXZA...

Samsung TV Model #UN46EH5000FXZA lost picture completly but still has sound. What do I look for?

Technician's Assistant: How old is your #UN46EH5000FXZA?

TV was bought in 2015

Technician's Assistant: Does the TV menu work? Do you have the same problem on all sources/inputs?

Have no screen at all. Totally black no matter what button I bush on remote.

Technician's Assistant: Anything else you want the TV Expert to know before I connect you?

Could this be a backlight circuit board, can I replace it myself?

Have looked at some other suggestions that it could be the backlight circuit board, could this be the problem?

OK, most likely it is the mainboard failure (EEPROM chip failure) and next possible cause is backlight LEDs failure mounted inside the screen that is a serious problem because the screen will take apart for backlight LED strips replacement

Please click the following link to get required identical replacement mainboard if you have a plan to work on it yourself

Ask Your Own TV Question

Mainboard swapping will either fix the issue or confirm it is the screen problem/ backlight LEDs failure and you can return the mainboard to supplier and get the backlight LED strips, but taking apart the screen is very risky as any wrong move will end up on broken screen

I hope this info will help. If you have any additional questions, feel free to ask.
