Where do I find a replacement remote control or universal remote control for my DSP-E492 Yamaha amplifier? TY

If you wish to buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. They can either give you a genuine remote control to your device, or can direct you, from where can you purchase a suitable one.
To select a proper universal remote control, you should know about the number of digits to its set-up codes. There are 3 digit, 4 digit, 5 digit, 2 digit and even single digit codes, to some brand devices. After confirming this, check the sites linked here. Both the sites have set-up code list and set-up procedure to many popular brand remote controls. Check which brand remote control has set-up code/s to your device brand, and buy that one according to availability. Brand name of the remote control isn't a matter, but it should have set-up codes in its code list, to the device brand you have.
Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its pack. Never accept a remote control, that hasn't both of this. For more details about the set-up codes, visit the sites.

Universal remote controls are available at most of the electronic spare part selling shops. Visit some on-line sites too, which deals with electronic spare parts.

Be careful - most universal remotes only control the most basic of functions, volume change, channel change, mute, on/off. They rarely include operation of sources, menus, etc.

U are , no doubt, going to need an original unit for the menu access.
Check for remote on ebay or google.

Hi,

found on internet thanks.

Are you certain they are at fault? It could be that the Yamaha isn't responding, due to a faulty remote censor. Try a good universal first to be certain, before attempting repair of the remotes.

Check ebay for a remote. There are also several online dealers that sell replacement remotes. Do a search using "replacement remotes" and you'll find most of them. If you don't have the owners manual, I suggest getting one. It can probably be downloaded for free at Yamaha's website.

THE MUTING CIRCUIT IS ON AND IT CANNOT BE DEACTIVATED BY UNPLUGGING UNIT...YOU MUST HAVE THE REMOTE TO DEACTIVATE.

Dear Zforce, The Yamaha DSP A1000 has three different options of on-screen display. Try using the On-screen button on the remote control in order to remove the disturbing display. If this fails or if your remote control malfunctions then you should contact Yamaha for further assistance.
