My DISH tv remote works sometimes and sometimes it doesnt. The only SURE way to get it to work is if i light up my phones screen and point that light, about 2inches away from, my remote. After ive done that the remote will work correctly. For one or two times of switching channels etc etc. After that i have to light up my phone and shine it on the remote again. This is very anoying. What is causing this? DISH has sent me new remotes. A new cable box. A new antanea. Ive replaced the batterys. Please tell me how to fix this problem

well to be honest i don't think shining your phone on the remote is making any difference, except your probably changing the height your holding the remote so it has a more direct/better line of sight angle to the box so it then works.

 

had a similar problem with a device once and had to change it's placement slightly so i didn't have to move my arm 5 inches to the right to get it to work.

 

apart from that i can't think of anything else that could be the cause of your problem, seeing how you've had new remotes and boxes and still have the problem.

 

 

some info on how infra red remotes work :- http://electronics.h...te-control1.htm

 

On the component side, the infrared receiver sits on the front of the device where it can easily see the signal coming from the remote control.

You've probably noticed that some remotes only work when you're pointing them directly at the receiver on the controlled device, while others work when you're pointing them in the general vicinity of the receiver. This has to do with the strength of the transmitting LED. A remote with more than one LED and/or a particularly powerful LED produces a stronger, broader signal.
