if not then may be another board probem

I have a UA40EH5000M samsung led tv. Suddenly the screen went blank. only sound is there, no display. Which part may have the problem..please suggest..

It sounds that one or two of its back-light CCFL lamp/s has burned out. Check it.

Blank screen , check for Video Drive circuits

Check power supply , could be capacitors

Check

Flyback Transformer

and surrounding components


hope these helps,

thanks for choosing Fixya for assistance!

Well, at least you got it sorted out and everything is working fine now.

It may be a problem in the digital section of the TV. If you find a part of the movie that blanks out, try rewinding back to it and see if it goes out again. It may also be the HDMI cable you are using. The blank out is often the result of the TV trying to adjust to the correct resolution for the program being played, and we need to diagnose why it is changing resolutions. Microwave interference and voltage fluctuations can also cause these issues.

the problem has sorted it's self out after 4-5 days

You need to check the back light is still on when the screen is blank (check through the back).

If the back light is on, need to change the Powwer Board.
but,
no back light, need to change the inverter.

its broke lol its mostlikely the sreen itself
just go andf replace the screen

i have a samsung LCD tv 32 inch tv. when switched on the pic is seen for about one sec then goes off. when i change channels the audio changes but the screen is blank. every time i switch off and on the same thing is repeated there is no display on the screen looks like a back screen light fail . can the problem be sorted out by changing the inverter or the whole LCD panel needs to be changed? pl be free to answer.
