The remote don't work. added new batteries. need a

Infrared sensor inside the TV is damaged. Replace it.

Your keyless entry system is going bad and you need a battery for your keyless entry system once you replace your battery with the new one thing should work properly

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

If the remote is not working,try to open the remote and check the battery terminal the one that is connected in the pcb if loosed, then if you have a cellphone with a camera, point the sensor in the camera lens then press any button, then try to look the monitor of your cellphone you will notice that their is a glowing red light it indicates that the sensor is in good condition if you do not see anything try to replace the sensor.

Hello,

If new batteries did not fix the problem, then it means the problem is either from the remote or the TV.

Remote: Check the remote battery terminal, see if its not rust. Also, disassemble the remote, can check the connection between the terminal and the remote board, see if there is no disconnection of any kind.

If after checking and all seems well, then it means the remote is defective. To confirm, borrow a remote, test it with the TV. If it works, then it means you need to replace your remote. But if the remote you borrowed does not work, then it means the problem is from the TV and not the remote.

TV: There is a sensor in the TV that communicates with the remote. If this sensor is defective, the remote won't communicate with the TV.

The TV sensor might have loosed contact from inside of the TV or it maybe defective and need to be replaced.

So do the above troubleshooting and let me know if the problem is from the TV or remote. If problem is from the remote, you need to do a replacement. But if otherwise, let me knows as well.

Lastly, please don't by a remote with confirming it is a remote problem. You have to be sure before thinking of a battery replacement.

Regards.

Have you tried replacing the batteries? Do you see any damage on the remote? Have you spilled any liquids on it? If the batteries have been replaced and it does not work, you may want to try reprogramming the remote control. If all that fails it may need replacement.
