Intermitten remote sensor issue

Evidently 2 good remotes point at the problem being the remote sensor on the TV itself. I have about 4 remotes I can adjust volume w/ including the remote that came w/ my samsung. The TV exhibits the same behavior w/ all of them.

Per the samsung site, the "test" for this (remote vs sensor) is to us a digital camera, (including the kind that's on most cell phones) to "see" if the remote lights up. Just point it at the camera/phone, and press any button. You should see a bright flashing light on the camera/phone's LCD screen. If not, REJOICE! All you need to replace is the remote or batteries in it. If you do see the light, good luck if you're not in warranty. I've been unable to find any procedures for replacing this kind of item.

Try taking your battery cover off and roll the batteries with your finger while watching that blue light. if works there intermittently then take a small screwdriver and put some more stretch in the battery springs.. dont break it now. also a cotton swab with alcohol or wd-40 on the contacts help.
