Does this keyboard have a button battery inside?

When you turn on your keyboard it carries out a self check to make sure all is OK, if not the start up procedure stops

It could be a fault on the mainboard, the rubber switched do wear but as the light is coming on it would indicate this is working

Try a master reset : whilst switched off, hold down the highest note (Top C) and whilst holding down turn on, after a few seconds if this is successful then the display will show up, this function resets to factory setup

If this fails you will need to investigae board connections etc inside the keyboard

Good luck

If it was just no working on power adaptor I would have suggested the socket was faulty. However as not working on batteries I would suggest it is the on/off switch.

From what I can remember the PSS680 used a slide on/off switch which when you look inside has a metal piece that makes the circuit on the PCB track. Over a period of time this can wear or get clogged up with dust etc.

The other thing you could check is, do you think a wrong adaptor might have been used. Check the polarity against the picture shown on the back of the keyboard. If it is wrong you may have blown some of the power diodes.

Sounds like the connections may be oxidised. With a long, sharp knife scratch at the metal contacts at each end of the battery compartment until they are shiny,and make sure your batteries have good life in them. If that does not work there may be a broken wire connection inside, or, less likely, a short circuit has occurred that is draining the batteries (I doubt that though)

Try a factory reset.

Turn the unit on, and while the display says "Please Wait", press and release the Panic button. Press the right arrow button till the display says "Hard RESET". Press Enter, then the button under "Yes" in the display.

If batteries or power adapter does not power up the keyboard...possibilities are...if it has a fuse inside or fusible link check it.replace if blown.Another possibility is power component has a short. maybe from constant movement of power plug into keyboard.sometimes just by inserting the plug and wiggling it can solve the issue..having this fixed by a technician can cost a lot of money.but,if your keyboard`s value is less than the cost of fixing it,might as well replace your instrument.

It sounds like one of the OTS buttons is getting triggered accidentally. There may be a build up of residue behind the button. With the unit off, try rapidly pressing the OTS buttons, one at a time. This should help to move any debris which may be creating a false contact.

If you are feeling brave, you can try opening the keyboard and getting inside, under the button with some electrical contact cleaner such as DeOxit or Servisol.But be warned: it can be difficult to get the parts back together properly! So if you don't have much servicing experience, call your local music shop to find a service technician.

Hello,

The battery needs to be charged before it will work in your keyboard. Maybe, the battery is out of charge that's why your keyboard is not working.

You need the wire to turn on the keyboard and at the same time to charge the battery. If the battery is already full, you can remove the wire and the keyboard will still work until the power in the battery is drained out.

I hope this helps.

This is the factory reset procedure: While pressing the three lower left buttons in the Rythm Group Section ( Soul&Disco, Gospel&Blues, Country&Western ) at the same time; turn the Power button on. If you don't have the manual it is here:http://www.retrevo.com/support/Panasonic-SX-PR903H-Music-Keyboards-manual/id/619ci856/t/2/ I hope this helps.Most keyboards have a memory battery inside that has to be eventually replaced also which might be the problem.

The 2013 button battery must be replaced to boot up. You should find or make a battery holder with two leads to replace the soldered in battery.

Normal 0 Assuming that you have good batteries installed, turn the Keyboard over and locate the small reset/connect button on the back of the keyboard and press it. Then try to see if it is working. If not try pressing the button on the receiver and then on the keyboard.
Turn the mouse over and find the small rest/connect button on the bottom of the mouse and press it. This should connect the mouse to the receiver and work properly. If not, try pressing the receiver button and then press the button on the mouse. This should be done whenever you change batteries or glitch.
Hope this helps. Bud
