Question about Samsung LA40A450 40 in. LCD TV
Try pressing the up/down channel buttons. If this doesn't work, try replacing the batteries in the remote. If that doesn't work, pull out the plug, wait for ten seconds and then plug the TV back in. If it doesn't work after this, you should phone the warranty providers/repairmen to have a look.
