My remote stopped working all of a sudden. The batteries are new, so don't think I didn't do that! At first it was the middle section that stopped working, now it's the whole dang thing!

if its not batteries it will be a replacement remote. try cleaning the terminals and see if helps,

You can reset your remote control by removing the batteries, pressing all of its buttons, and installing new batteries. Also, ensure that your TV's sensor is clean and unobstructed. If the problem persists, try using a universal remote control as a troubleshooting step. This will help identify whether the original remote or the TV is at fault.

Hi:
The IR receiver inside the television is becoming intermittent and needs to be replaced. You might also check the connections on the receiver small circuit board for cold or loose solder joints.

with Hampton Fans,, normally if the remote is good with a known good battery , and it quits working,, its the remote receiver, not the actual remote that goes bad. you can contact these guys I heard they have the part you need http://www.ceiling-fans-n-more.com/hampton-bay-ceiling-fan-parts.php

Hello
You might have a cellphone with camera option. Set the cellphone co cemera mode, and place the remote control at about 1 feet away from its camera lens, and press each button on your remote control. Remote control emits infrared rys as we press each button, but can't be detected by human eye. Electronic cameras can detect it. If there is any infrared ray emission from your remote control you will see its image on the camera screen for each button press to your remote control. If there is image and still the Tv doesn't respond to it, The TVs' infrared snsor inside has damaged and should be replaced. If there isn't any image; check the battery contacts of the remote battery compartment first. Clean these contacts by using a piece of corborandum paper or with the tip of a razor blade. Improper battery contacts, due to rust and dust to these contacts will prevent the battery supply voltage to enter into the remote contro.
Still it doesn't work at all, the remote control is damged and should be replaced. Contact the nearest Vizio Authorised Service Cente fro original remote control. OK.

Just in case, I'll ask, Did you also change the remote receiver batteries, located behind the fan's cowling? If not, that should do the trick. Don't feel bad if you didn',most folks do remember they're there.
