About 6 months ago, towards the end of a performance at a nursing home, my PSR3000 turned off and on. It did this a few more times during the show.

I did some troubleshooting at home where the problem repeated itself several times. I ruled out the adapter (I own three adapters). Why was my PSR3000 turning on and off?

I brought it into my local authorized repair center, and the repairman could not replicate the problem. The keyboard worked fine, and he couldn't find any problem inside the keyboard.

I brought the keyboard home. The problem repeated itself at home. I used my other PSR3000 for gigs. It took 6 months of playing at home for the problem to reappear.

I took the keyboard to the repair center again, and this time the mechanic could see the problem. But he couldn't figure out what was causing it.

He called Yamaha technical support. They informed him that they have two keyboards that are doing the same thing, and they can't figure out what the problem is. So they basically told my repair man, "Your guess is as good as ours."

I'm going to speak to him tomorrow, but I'm nervous that I'm either going to have to junk the keyboard entirely or I'll have to pay for a new main board. I don't know what. All I know is that the guy charges $75 an hour, and his secretary told me that he's spent hours trying to figure out what's going on.

I'm bummed out.

I had that problem with another brand keyboard spent months trying to figure it out and they found it was either a small crack in the circuit board or the ribbon cable connecting two circuit boards inside.

The explaination was when you put it on a stand with two support points ( like an X stand), not to mention the moving set up tear down ride in car, it bows the board just enough for the contacts to come loose.
If you set it on a table the problem would not soon repeat itself.

I don't know if this is related or if this helps,but the symptoms sound the same the board would shut off. Sometimes it would shut off and come right back on and reboot.

Larry,

This was a problem with the 2000, 740 and 540. In nearly every case it was a poor solder joint on the small board where the power supply plug plugs into the keyboard. I fixed three of them myself for guys that live in my area. On one board, there was no solder at all on the connections. The wires were just poked through the printed circuit board and no solder was applied during the manufacturing process.

If you have a small soldering iron, try resoldering the connections that connect the power supply jack to the printed circuit board. This could very likely solve your problem.

As for the weight of the keyboard bending the PC board--it cannot happen. Well, maybe it could if an elephant sat upon a keyboard supported by an X-Stand. The normal weight of the keyboard, and the construction angles would prevent any flexing of the case.

Good Luck,

Gary

That's kind of sickening. Kinda spooks me about psr3000 but I guess they've sold thousands. Of course, many other people might have the same glitch and not know it or not report it.

As there've been reports of pink elephants seen at places I've played (aka: bars), perhaps this explains it.

Seriously though, Gary's poor/weak solder joint explanation makes MOST sense to me. As gigging musicians, having to repeatedly insert & remove the power cord plug into our kbs puts excess stress on the connection point of the board where the power cord plugs into. I really don't think Yamaha designed the PSR3000 to stand up to the rigors of constant daily setup & breakdown. Perhaps it's time for Yamaha to consider releasing a more road durable version (including XLR mic input) of the PSR3000, yet still maintaining its appealing lightweight & compact size. Larry, hope that a simple re-soldering of the power cord plug connector board solves your problem. Keep us posted.

Hi :

I just read your post, I am almost 99.999% sure that is the false contact where you conect the adaptor, like Gary said, I see it when our customers that like you, play out constantly and conect and disconect the power adaptor, makes that situation possible, so you can say that is kind of the PSR 3000 weakness for a lot of use, this do not affect our hobbiest customer, since their 3000s stays at home.

Bill,

When you take into consideration the huge volume of PSR-3000s that have been sold, the percentage of keyboards with problems is likely less than 1-percent. Keep in mind that most electronic devices are no longer inspected to see if the function properly. Most manufacturers have determined that the percentage of factory defects is so low that it doesn't pay for them to have a person checking out each piece of equipment before it leaves the factory. I have a friend that worked for a major computer corporation who said they may have .01 percent defects during an entire manufacturing year.

Personally, I play every day, both at home and on the job, and have never experienced a failure of any kind with any of the Yamaha keyboards I've owned during the past 15 years.

Good Luck,

Gary

Is there any way you could leave the plug in?

If this is a problem with the board, should Yamaha be responsible for it?

t.

Gary sounds like he has the right solution, I guess I was trying to say was it was probably a loose connector.
The other board I refered to was an old ensoniq and the factory explaination was there was three circuit boards and ...well you know the rest, they no longer make keyboards (that I know of).
But we had the same frustration of going to many techs, many times, for over a year until someone discovered the problem.

Good luck and let us know how you make out.

Thank you guys for replying to my problem. I have been having internet connection problems, and I am at my local library. I am going to forward this stuff to my technician who is running some tests on the keyboard.

Correction: Yamaha has one PSR3000, not two, that is doing the same thing, and they cannot figure out what's wrong.
