Direct TV remote quits working - conflict with Samsung LCD?

You likely don't need a new remote. Certainly not a Universal.

Samsung remotes for LED / LCD TVs are generally RF, not IR.
Most Universal remotes do not generate RF signals, so disregard advice about codes for Universals.

Try this:

First, fresh batteries, and clean battery contacts if needed.

Then, Try Pairing procedure:

1. TV off
2. Bring remote within 3 feet of TV
3. Push Pairing button (Paper Clip or other pointed object in button hole)
4. Turn on TV
5. Should be paired. Try remote channel or other buttons.
6. If not, try 2 more times.
7. If still not working, push RESET button first and repeat Pairing.

Please rate if Helpful.

Good Luck !!

No it may mean that you need a new tuner

if you look inside the battery compartment there should be a revision number for the remote.

for a LE40b652 use -

Rev 4 or 6 Remote - 0646 or 0502 or 0615

Rev 8 Remote - 0646 or 0840 or 1340

more likely the remote sensor is misaligned in the tv, and it needs to be pulled out straightened and replaced back in , maybe even the receiver board will need to be replaced. they are small in size and if the tv is in warranty then it will be easy to get it replaced.
the picture does not interfere with rf or ir signals the image is passive. to check the remote you could simply tel direct that the remote stopped working (no matter what tel the phone person it doesnt work...
that will get you a new remote and then you will know if it is the tv or the remote.

Get a new universal change bateries

10178 or 11331 or 11610, depending on the model of your remote.

Correct solution WITH DIRECT TV is NOT going to SETUP MENU on your Samsung TV and enabling it, this won't work with Direct TV!! I'll walk you through it. Grab your Direct TV remote, hit "Menu", pan down to "Parental, Fav & Setup", next click "System Set-up", next click "Display", now at the top of the screen between "Preferences" and "Clock" is "Captioning", click on it, now the first box reads Captioning TURN IT FROM OFF TO ON! You now have Captioning.
