Samsung LE40R51B no picture but turns on

Hi there
I would go to menu on the remote , from there to picture go down the list, if you do not find anything there to help you. Go to Support and to the E manual .

Here is what to check when your TV is turned on, power light is ON, but no picture is seen or sound is heard:

1 - Be sure the component you are using (Xbox, Cable, SAT, ROKU) is turned ON.
2 - Check to be sure all cable and cords are securely connected to the TV inputs and component outputs.
3 - Make sure you are on the correct input as some TV's will show a black screen if there is nothing connected to that input.
4 - Unplug the input you are trying to use from the TV (such as an HDMI Cable) and plug it back in.
5 - Check for signs of damage on all cords and cables from the TV to all components.
6 - Make sure the TV is not in ENERGY SAVE MODE, press the button on the remote control to go back to normal mode.
7 - Unplug the TV for 10 minutes to see if there was a temporary one time issue with the TV.
8 - Disconnect the TV from power for 2 minutes, then when plugging it back in PRESS AND HOLD THE POWER BUTTON ON THE TV FOR 10 to 20 SECONDS to try and force the TV to reset.
9 - If after checking all these different issues, you may have a Faulty Power Supply Board, A Bad Capacitor on the Power Supply Board, Loose Wire Harness, or Loose Ribbon Connector in the TV itself.
10 - Most likely when a TV has the power light ON but NO PICTURE and NO SOUND, it is the Power Supply Board that has failed.

BTW, here are solutions for you to play iTunes movies on Samsung smart TV

While this is not a permanent solution, we've fond it helps... We have a Samsung LCD that does not turn on when there is too much humidity in the room. This only happens in the summer when it gets really humid. We moved our dehumidifier next to it, let it run for around 15 minutes and the TV turned on again, no problem. Lately, it's been raining alot so it's very humid. We've gotten into the habit of leaving our dehumidifier on through the night on low and we've had not issues turning on the tv since then. This is a hastle but it's either that or buying a new tv.

i've just some digging around and found that you can access a service menu and perform a reset which sorted the issue for me.

Access the service menu by pressing, in order, whilst the tv is in stand-by mode:

info
menu
mute
power

when the tv comes back on you will have a service menu; select option 12 (reset) the tv will then switch off.

this will reset your TV back to factory defaults.

turn tv back on and you should be prompted to go through the plug and play setup again - go through everything and then all should start working OK (it did for me)
