Yamaha RX-V359 the remote sensor in in the unit is not working. I have tried the remote control on another machine and that works

To perform a factory reset on a Yamaha RAV 352 remote for use with an RX-V2500 receiver, follow these steps:
1. Turn on the RX-V2500 receiver using its power button or remote control.
2. On the remote, press and hold the "VCR 1" and "ON/STANDBY" buttons simultaneously. Hold both buttons for about five seconds until the remote's indicator light blinks twice.
3. Release the buttons. The remote control should now be reset to its factory default settings.
4. Test the remote by using it to control the RX-V2500 receiver. Make sure the remote is within range and pointed towards the receiver's IR sensor.
If the factory reset doesn't resolve any issues you're experiencing with the remote control, you may need to try replacing the batteries or consider getting a replacement remote from Yamaha or an authorized dealer.
Please note that the steps provided are based on general instructions for Yamaha remotes, and there might be slight variations in the specific procedure for your RAV 352 model. Consulting the user manual for your specific remote or contacting Yamaha customer support can provide you with more accurate and detailed instructions tailored to your device.

You need another remote, just buy one! $23 on Amazon.

Most Yamaha receivers have a remote ID so if you have more than one Yamaha you can control one without bothering the other, do you still have your owners manual? If not have you tried the people at Yamaha they are very helpful with a problem like this but for an example I have my Remote ID set at ID1 because I do have 2 Yamaha receivers the RX-V1300 and the RX-A3020, see if you can find the section in your manual that talks about remote IDs and let me know if that fixes the problem and you can always goto http://usa.yamaha.com/products/audio-visual/ but that is the site for the United States they do have sites for many countries at http://www.yamaha.com/

sounds like you need to take it in to have it looked at. no simple fix unless you are an appliance technician. hard to walk a beginner through. i suggest calling an stereo repair guy.

Since Insignia and LG share compatible codes for digital-to-analog converters, review your remote control's manual for LG VCR codes as they should work to control the Insignia converter.

Replace the remote control with a universal remote (e.g. Logitech). It is more advanced and very user friendly with a help function if anything doesn't work.
Just follow the instructions in the unit's manual.
If you drop it; be sure to replace the batteries correctly.
Keep good batteries in it and enjoy the convenience of only one remote.
If still in trouble; just visit your local Yamaha dealer for help.

Try reseting the Yamaha-Shut the power off, and while holding down presets 1,2 and 3 press power on.

The volume keys should be working by default, but you may have volume punch through turned on (meaning the remote is sending signals for TV or CABLE volume function no matter what mode you are actually on). To unlock volume control for AUX mode, do the following:
1. Press and release AUX
2. Press and hold SETUP until the remote blinks twice
3. Type 993
4. Press and release VOL-
The remote should blink four times to confirm unlock.

The types of remotes are as follows

- Single item, or fixed. This unit will only operate the unit it came with
- Multi function, this type can operate the unit it came with and a fixed set of other types. Normally the remote comes with a list of supported device it could work with.
- Learning, the combine both a predefined list with the ability to learn functions by sensing input from the original remote.
- Programable. These are the newest remotes that work like multifunction but the list is maintained by the manufacturer and down loadable from the web.

I would guess that the DVR has a multi function remote.
If you can't find the specific Yamaha in the list, then
try another brand, this could take a while.

Some multi function remotes have an option that allow a semi automatic configuration.
You turn on the item and then using a special key sequence try to turn off the device. once the item turns off you should be able to control it.

If you can't the Yamaha has a learning remote. If you really want an easy solution try looking at a programmable remote. I just got a Logitech, (Harrmony). Life has never been so easy.
