Psr-s500; no display at all but everything else is working properly.

Connect shows when USB flash drive used. If Connect is not showing I would expect this to be a non stand USB drive or the drive is not formatted

Look at the back of the keyboard,there is a small knob that controls the screen clarity,turn this to fix it,if that don't work,you need to get the screen replaced.

guys i am using psr s 550b for 2years,,.and the problem was i stopped useing it for 2 months ....and when i started using it again my keys r not working only the styles r playing ....and i thought to do format since the keys r not working i am enable to format it ple tell me any solutions for it .ple.pleeeeeeeee

The display is an LCD. From your limited description, it would appear that, electronically, at least, everything is working correctly, but perhaps the LCD has become warped or damaged.

Yamaha has a parts order website, but you would need to create an account to actually order the part, AND you would need to know the part number of the LCD. Not only that, but you would have to perform the repair yourself - - - not recommended, unless you're an electronics geek already. ~LOL~ But if you want to take a look, here is their parts web site:

I'm assuming you're in the U.S.A. If you really wish to talk to Yamaha about the part, they do have a number you can call: (888)892-6242

Prior to making the call, be sure to write down the model# and serial# of your keyboard. It is probably found on the back or under side of the unit. They will advise you on the availability of the part.

Another alternative is to go on Ebay and search for PSR-S500 under the category Musical Instruments.

You can locate an authorized Yamaha dealer at this web site:

Problems like this are a REAL PAIN in the you know what, and I know how aggravating it is to have to spend money on a repair for an instrument you've already paid over $500 for. I'm assuming this is an out-of-warranty situation.

Anyhow, good luck on getting this fixed, and let us know how things work out.

Thanks ~Jim :-)

It is shop replaceable. I have heard this is NOT an uncommon problem. You can get the parts through Yamaha America in California. Here is your service manual:

Check that your adapter is a 12VDC with a current rating of at least 1 amp (1000ma) AND that the center pin of the connector is the POSITIVE.

1. Try the volume

2. Your adapter may not be the proper voltage/amperage. If the adapter has ratings listed, make sure they match the keyboards ratings.

3. Try it with the headphones. If they work and the speakers don't, you've narrowed down your problem. There may be some damage or wiring problem within where the board meets the speakers, and/or before processing.

4. Try it with batteries. If that works, you need a new adapter.

Turn off the "ACMP" button... that is the "Accompaniment" function that controls whether the "Style" you select will accompany your playing or not...

The key removal is around page 15 of the file.

The computer processor in these is NOT subject to the viruses like PC's are.

Do a factory reset on the keyboard to restore factory settings.
