PSR-2000 will have to sit in a corner until problem figured out :(:(:(

Until I figure out what's producing all that static in my PSR-2000's speakers the board is just going to have to sit in a corner. I can't play it with that noise, and it really stands out when playing now. It's frustrating having to move the board around my entire home trying to find a clean spot (which most often is dead center in a room). I know I'm going to hear it from the wife now. She was against me getting the board in the first place. Now I'm sure I'll get a big ass "I told you so"

Right now I'm at a loss as to what I should do. The problem is localized, and I have no idea on how the hell to pinpoint what signals I'm picking up that cause this problem. It is the only electrical device in my home that I have this problem with. My Casio WK-3500 doesn't do it and no other device in my home with speakers has this problem. I honestly don't know what Yamaha can do about it either. So currently the board is unplayable to me and will sit for I don't know how long until I figure something out.

Check your gain, if it has one. If its too high its guaranteed to cause the noise. Have you tried different circuits in different rooms? Often times when the circuit has too much on it and when you turn on a ligh or something it will cause clicking or popping. Try using studio monitors, or headfones, if the sound remains it may be internal.

Phil,
I've tried every available outlet in my condo. And it's the same in every room. Turning down the mic input level was one of the first things I did, and that did not help. I later found that static is also present in headphones, and in the output jacks. The noise comes primarily from the tweeters. The speakers I used were a PC based set up with two satalites and a subwoofer. The sats didn't have tweeters so the noise wasn't as loud because the tweeters weren't there. I then hooked it up to my stereo system, and since those speakers have tweeters the sound was louder. I'm beginning think it's an internal problem with the amp. It's possible it got damaged during shipment. Currently I don't know what the heck I'm going to do. I spent a good chunk of change on the board and right now it's unplayable in my home. I don't know anyone who's qualified enough to open the thing up and take a look. The nearest authorized repair center to me is hours away, and I have no idea what they'd charge. I also don't know what Yamaha would charge me either considering the boards not covered under the warranty anymore.

Well id suggest calling the place to see what they could do for ya. Im sure they can quote ya something in the ball park. Major companies such as Yamaha shouldnt have a problem helping you as long as you send them a proper and repectful e-mail. They can also help you with troubleshooting. Shoot off a few e-mails, and see how it goes.

Phil

Was the shipment insured? You might be able to make a claim if whomever sent it stated that it was in fine working order before being shipped.

Just a thought!

Just some thoughts....

Is this interference coming down the mains wire, through the air, or is it the 2k itself?

SO

Try feeding the power apapter through a main filter or (even better) a PC UPS system. Can you get your hands on a portable generator - try it in the garden!

Is the behaviour the same at a neighbours house? Different block / town / state?

Do you have light dimmers in the house? Dodgy flourescents? Does the noise go away if you turn off the Lights / TV / Freezer / Fridge / Aquarium?

Squeak, you've got mail

Desperate times need desperate measures:

Supid enough, but maybe do factory reset???

After reviewing both threads of this topic, I think I understand your problem more. You can forget plugs, grounds, locations, etc: Your keyboard is not filtering to ground rf thats surrounding you, You could be located in a high density area of rf. That is, radio staion across the back fence etc, but not to likely, Would be helpful if I knew if this just started or has been the case since you first plugged it in.
Trident's idea isn't so dumb in my opinion. A re-install of the OS is a possibility. I had a similar situation one time and the OS re-install cured it.

Its sorta like a portable tv with rabbit ears. you get close to the antenna and it changes the picture, or if you touch it you become the antenna, when you get close to the board you are a antenna for rf and help the amplification out. the metal stand is also a antenna. I think the 2000 is defective because it should filter this out. but it could be possibly cured by a re-install of the OS. If this dosn't do it, it's time to send it to a pro. It could be something very simple a wire rubbing against something (caused be shipping or handling) or some small component has failed,or a loose ground wire etc etc....Hope you get it fixed......Pose

Unfortunately, even though it was widely advertised as having the OS in software, the PSR2000 in fact does not have an upgradeable OS, unless you change out hardware (chips).

Thanks for the advice. Like Don said the OS is fixed and not upgradable.. Yamaha originally advertised it as upgradeable but later retracted that statement. I did factory resets and the problem is still there. It was there the moment I turned the board on right out of the box. Here's what I think happened. I think the board took a knock during shipping, and some how damaged the amp because the sound is in the speakers, headphone jack, and output jacks.

Boards I've had in the past with faulty amps were a little tricky. They were more sensitive in some environments and not in others. Even though the noise wasn't there when I took it to another home to test, there was still a considerable amount of "white noise" (hissing) even with the volume all the way down. Teh hiss can be heard while playing too.

I did a very detailed inspection of the board today and found something. I ran my hand over the right speaker grill and it was smooth without any dents. When I ran my hand over the left speaker grill I could feel an area where the grill has been pressed in. It's hard to see (need to look at an angle), but it's there. I'm speculating that it took a knock on that side.

I've contacted Gary regarding the possibility of filing a claim with FedEx for damage. I know this board wasn't damaged when Gary shipped it. Those of us who know him know that Gary pampers his equipment. I'm waiting to hear from Gary and I guess we'll go from there.
