Question about Samsung LN40A450 LCD TV

1 Answer

Black screen. screen doesn't turn on...and yes it is plugged in. cable is also plugged in and the batteries have been changed on the remote. we tried turning the tv on via the buttons on the side and this does not work either. When you unplug the tv nothing happens on the screen...it stays black. When the tv is plugged in...the screen still stays black however the little red lite on the bottom edge of the frame blinks. That is the only sign of life.

SOURCE: Monitor stuck on black, menu buttons not responding

It's sort of a solution, but I work in a computer shop and got this screen in yesterday. I looked at it closely and it's actually the backlight that died. I pulled it apart and found that three of the 820uF/20V capacitors had swollen up. If you replace them then you should be fine, but I went for a different approach and took the inverter board from a laptop and put the in the screen and used an external power supply. It's a bit dark but it works fine now.

Remote control won,t work

This is how to complete a remote reset for a Sharp television:

Turn off the television if it is on. Unplug the television. Please leave it unplugged. Take the batteries out of the remote control. Leave the batteries out of the remote control. Is the television still unplugged? Yes? Good leave it that way. Are the batteries still out of the remote? Yes? Good leave them that way. Point the remote at the television's remote sensor. Hold the power button down for 30 seconds. Release it. Press and release each button on the remote control. Plug the television back in. Turn it on with the power button on the television itself. Replace the batteries. Try adjusting the volume. Hopefully the remote works. If it still doesn't work the remote sensor on the television could have gone out or you may need a new remote. http://www.sharpusa.com may have a remote you can order or http://www.replacementremotes.com but if that isn't the problem you may or may not be able to return the remote.
