Question about Logitech Harmony 520 LCD Remote Control

1 Answer

New batteries, remote works for a few, then starts beeping

The remote only works for a few minutes before it starts beeping and it will not respond to any commands. I eventually just have to remove one of the batteries so it will stop. When it is beeping, the screen says USB Connected (even though it is not) and that stays on the screen with no response from any button. I have been told it might have something to do with the firmware installed on the device.

Update your software, then update your firmware to the remote. have it connected without batteries and then when prompted to connect the remote, add your batteries and see if the software will connect and update. Good luck.

The tv doesn't respond to remote commands. I've change the batteries. I get a slow response then nothing for a few minutes. Can't even turn volume up or down


Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. Surf the site with patience. In some cases, the remote control might need to clean.

Remote start


The remote is in the middle of its 'setup' re-programming cycle, one of you has accidentally put it into this mode. To switch it back to normal mode remove the battery from the remote for about 10 minutes.

I have a 2006 Chev Trailblazer with the RPN 474V/P/C starter and alarm. Everything worked fine for a few months and then the number of beeps the remote changed from 2 beeps to 4 when the locked button was...


Hi. I'm going to take a stab at this. You say it corrected itself after the battery was out of the remote. Now it is doing it again. I think you can rule out the console and go right to the remote. I would go down, get an exact copy of the remote. The reason I say this is because of the change in beeps, from 2 to 4. The signal is corrupt, the reason for the different beeps. There's a little circuit board in the remote, that can go bad just because of the abuse it gets. I hope this will help. If not, let me know and I'll check the dealer.

Remote will not work tv.


A working TV remote is a security blanket that allows us the peace of mind of knowing that we don't have to get up unless nature calls or the house catches on fire. People are more likely to spend more time and energy to fix their TV remote than to get up and change the channel. There are a number of simple fixes that can ease your mind when your TV remote is not working.
jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); }); Difficulty: Easy Instructions Things You'll Need:

  • New Batteries
  1. Check the batteries. Make sure the batteries are in correctly and, if they are, replace the batteries. If the batteries are dead or are not in correctly, your remote will not respond and the LED light will not illuminate when a button is pressed. Make sure the TV is plugged in. An unplugged TV will not respond to any remote.
  2. Check the selected input to make sure the remote is set on the TV and not some other device programmed into the remote, such as your DVD player, VCR, or video game console.
  3. Reprogram the sync code. If you are using a universal remote, it may have deprogrammed, leaving the remote and TV out of sync.
  4. Unplug the TV for a few minutes. During a power surge, a TV can become "confused." Unplugging it for a few minutes will give the TV the break it needs to sort everything out and work properly with your remote.
  5. Use another remote on the TV. Program a universal remote to work with the TV. If the TV does not respond, the problem is likely with the TV and not the remote control.

You have to get the remote and transceiver to talk to each other. Remove all the batteries and wait a couple of minutes
before replaceing them. Place the transceiver in the REMOTE
position, press and hold down the LEARN button, and then
press the MODE button on the remote control. A change in the
beep tone will be heard and you have MARRIED the two devices. Should solve the problem.

Oasis airconditioner broken


Unplug the unit for about 5 minutes and then plug it back in. If it still does not respond to the remote after that something has happened to the control panel. It should take 3 minutes after the unit is unplugged and then plugged in again before the compressor starts. (Self protection circuit) You can try turning off the circuit breaker and then turning it back on again also. I believe that your unit will work fine after trying these recomendations. Good luck.

My battery ran low and I jump started my car which some how caused the problem. My viper technician made me a buy new remote but the problem continued even with the new remote.
Try disconnecting the battery of your car for ten minutes and then reconnecting it. It worked for me. Now i have a extra remote which i don't need.

Won't turn on


I had something similar happen after five minutes. The included batteries are crap, try some rechargeables or brand new alkaline. Be warned this camera likes to eat alkalines but does well with nimh.

Faceplate not responding / acting very weirdly


Sounds like a bad connection with the faceplate and the multi connector that the faceplate mates with when closed. check for dirt and bent pins on both connectors. Luck
