Question about Akai LCT2715 27 in. LCD Television

1 Answer

I have a samsung le46m51b with backlight sound but no picture

The screen is blue/black but lights up slightly cos the back lights are working as you change channels the screen slowly goes darker each second just like a pulse no pixel movement whatsoever, any ideas, many thanks if you have.

    Hi thanks for your reply, I am not sure if the answer is for my set, only the email I received said it was for a LTC2715 27, and mine is a samsung 46m51b, I just wondered if the backlights are working ie. they are lit and you can see them lit from the back of the set, does this still mean that the inverters are faulty, or is it the screen control board at fault No.460wsc4lvo.1, many thanks Neil.

    Many thanks once again, will this be the inverter on the left or the one on the right of the set looking from the back, I assume one is the master and the other a slave, many thanks once again Neil.

It's the back light inverter.
they are common to fail. you will have to change that board.

    no, the back light inverter is the one that powers on your screen not the lights in the back.

    it's going bad that's why it gets darker.

    you will experience a black screen but you will have sound.

    that's when it died.

    is just a card and can be replaced, you will have to take the other one out to match it up.

If this is an LCD TV, show a flash light on the screen from a safe distance. If you can see picture, it means the backlights have gone off and the TV might need servicing.

Picture gone from TV Model LE46M51B

I suspect that your backlight has gone out. If you shine a light on the screen can you see remnants of the picture that should be displaying? If so, it's definitely the backlight, and most likely the power inverter for the backlight. You can probably find a replacement inverter, but you may need a repair manual to install it. I'd recommend checking the warranty status first and sending it in for repair if you can.
