LED 36" SAMSUNG TV has no display but only sound

[harshali]

my SAMSUNG LED TV is approx 03 years old. last week, suddenly, the display went off. There is only sound. No sign of any display in the TV. Sound is still of very good quality. Please help me to fix this problem. Does it get resolved by resetting the TV. If so, how is resetting done ?

Hello.

When the picture goes away and the sound continues, this is usually the backlight. You can try resetting the TV by unplugging it from the wall socket and letting it rest for around 2 hours.

If you plug it back in and there's no picture, but sound, then it's two things:
1) Your LED are broken. VERY VERY common.
2) Your power supply has issues. (uncommon)

Can you still see a picture if you shine a flashlight on the screen at various angles?
