First of all they are metric fasteners. The best thing to do is measure the diameter of the hole with a metric of English ruler, then measure the depth of it with something skinny Using that info go to a hardware store and look for a fastener that fits the description. There are going to be different thread sizes. Get one of each and try them out to see what is the right one.

turn it off, then get a Tech ?

Could be bad connection of the LCD glass to it's socket. You need a specialist to look at that, very delicate. If not---- Change the screen, probably the whole board with driver chip. Check with Yamaha.

Contact Yamaha agent in your area, or take the "dc in 6765" to an electronics component store. If this is a DC power pack that you're describing, just get the same equivalent or higher amps rating at same DC volts. DC plug must match size to piano socket.

You should try to contact Yamaha through their customer service/email and include the serial number.

True

Just a shot in the dark but a lot of keyboards allow for splitting the keyboard in half or even in quarters to assign multiple sounds... have you tried a total reset? Or explore the manual for setting up a split keyboard. Might help.

Try unplugging it and also remove batteries if it has any. Then plug it back in and everything should be back to factory settings. I don't know what to to beyond that.

Purchase a new power supply.

first - check the power supply if it's really giving power. Get voltmeter or plug it to something else you know it's working. If you are sure it does and still nothing, you need to check the fuse inside the P80. I've been there, it's not so hard to open it (from below of course) BTW, it's advisable to user surge protector on such delicate devices like computers and keyboards if there are any fuses that have blown. I can't tell you how many times a blown fuse has stopped equipment from working. I had a blown fuse go in a microwave oven a few years back. I called a repair guy while on a job to fix my Leslie (many years ago) and the culprit, a blown fuse. I could have fied it myself if I had given it more thought. Check the internal fuses first and you might save some money and a trip to a repair center. , sometimes a fuse can look good even when it is blown. If you have a voltage tester do a continuity check on the fuse just to be certain.It's possible that the P80 does not use internal fuses especially since it uses an external 12 volt power pack There might be info on the fuse in the P80 manual. Otherwise try Yamaha support. A lot of low volage gear run of AC adaptors is unfused. Another possibility is that the power connector or switch on the P80 is broken. DC power jacks are liable to get broken solder joints due to movement, especially if they are circuit board mounted and not chassis mounted. If you know what you are doing test the connector and switch with a multimeter. If they are good then also check the wires from the switch to the main board. They a probably connected with a plug, which itself can come lose. You can test for bad connections with the power off. Only test with the power on if you really do know what you are doing! You won't electrocute yourself but you can easily damage the keyboard if you are not careful. Unless you are experienced in electronics repair that is as far as you should go.

Yamaha's have little rubber "contact strips" that run under the keys. These strips have little rubber buttons on them, exactly like your tv remote. When you push the key down, it pushed the rubber button down and make an electrical contact. These buttons eventually fail and separate where the bottom of the button meets the strip. You have to replace the strip (different sizes, depending on where on the keyboard it is) but they aren't cheap. You can find them here http://syntaur.com/yamaha_psr.html but sometimes you can find someone selling them on ebay cheaper. If you only need a single strip, or maybe two, it's probabaly worth it. More strips than that and you may find it cheaper to buy someone's broken keyboard on ebay and take the strips out, especially if it's broken for a different reason, like won't power up.

If it was playing fine and just stopped working while you were playing it, it's possible the speaker has failed, or a wire has come off. It is likely something you cannot fix yourself, and should find a local music store, like Guitar Center, who can repair it for you. It's generally not a very expensive repair at all. If the sound stopped working from one side after you were playing with some controls or editing some voices, you may have set the panning all the way to the right, which would cause no sound to come out of the left speaker. In that case, you would simply need to set the panning to the center again while in editing mode. If you are not too familiar with the editing features on the PRS 330, and not sure how to set the panning to the center again, you could always simply reset the unit to it's factory settings once again, while will return all the voices, effects, panning, etc. back to like the unit was when it was first taken out of the box and turned on. Here's the process to reset the Yamaha PRS 330 back to it's original settings - Restoring the default (factory-programmed) settings While holding the C7 key (right-most key on the keyboard), press the power switch to turn the power on. This operation erases backup data in this instrument (including backup settings in the Function mode) and restores the factory default settings. The User Songs and the external Songs stored to internal memory will be retained None of that works and you do need to have someone look at the unit, here is a link to the Yamaha Authorized Service Locator to find the nearest authorized service center near you - Servicer Locator

Tune it.

Check to see if the unit can have the electronics reset to factory defaults. Look in manual or go to web site for help.
