We just got a new vizio tv and we have all the same receivers. we have a 722 receiver but the ir remote will not work.

possibly bad batteries in the transmitter. could also be a blocked IR receiver at the TV(do you have something in front of the IR receiver in the TV?) last resort could be either IR receiver PCB or the MAIN PCB.

It is possible that those buttons have failed, but a bit more likely the remote lost the codes for the TV itself... since almost everything the remote controls... is on the DVR. I apologize if I am guessing wrong in assuming other "TV" buttons (like INPUT) don't function either.

To re-program your remote to recognize your TV (like when the tech first set up the system) choose from the following receiver types to find the correct remote control TV codes for your Zenith.

Remote TV Codes for 722/622/612/411/222/211 Receivers
Remote TV Codes for 625/522/512/510/508/501 Receivers
Remote TV Codes for 811/381/322/311/301 Receivers

jholsinger1,

It sounds like this is TV 1 that you are having this problem with the remote, is that correct? What has changed from when the remote was working till now? Was anything moved like the TV/receiver? You may have some type of interference with the UHF signal. Without getting more specific information, I'm generalizing the trouble shooting steps. Would you clarify if it's TV 1 or TV2. Please post to this site and I will respond back to you.

It can be the IR remote receiver board inside the TV. Is the new remote setup for VIZIO TV?
Old VIZIO remote is bad for sure?
Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

judileighahl,

If you have replaced batteries and had a new remote sent out to you, either the Vizio TV is emitting an IR signal that is interfering with the remote IR signal to the receiver. To test if the TV is emitting interference, is it possible for you to turn the receiver in a direction away from the TV and see if the remote will work? If it does work after moving the receiver, that indicates interference from the TV. If it doesn't change the situation, you might check for other interference from other components (florescent lights, etc.). I hope this helps.

Had same problem - turned off Adaptive Lumina, Backlight control, and Ambient light sensors on the Vizio advanced picture settings and the Dish remote now works. Vizio was emitting an infared signal that interfered with the Dish remote signals with these settings on. TV still works and looks just fine... But best of all Dish remote works too.

Not all remote are compatible with all our receivers. Depending on the receiver and remote model numbers, if they are compatible you can readdress the remote to the receiver. I have provided a link for readdressing the remote to the receiver. I hope this helps.

I had the same issue with the 55LD520 and my Dish 722 receiver.
Check out this link for some suggestions:

Putting black tape over the receiver IR sensor seems to be working for me.

You can try speding $20 for the new IR receiver
http://www.shopjimmy.com/vizio-3642-0042-0189-ir-remote-sensor.htm to see if it will fix the problem, worst case will be the main logic board.

It seems the new, larger tvs these days put out too much light and it interferres with the remote signal. Simply put a post-it note or tape a piece of paper over the lights on the receiver and you have an affordable and instant fix. This isn't a good looking fix and I would be upset if the set were in a living room. Luckily ours is in the family room downstairs.
