My Yamaha electric piano, P80, will not power up


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.

Spb karaoke machine blown fuse 250volt 2amp changed it checked plug in wall still no power what could it be pls


You may have blown a component of the power supply, which is what took out the fuse in the first place. Probably will need a trip to the repair shop.

BEHRINGER K3000FX will not power on


It may be likely that you've blown a fuse. This will require removal of the amplifier unit from the housing. The fuse is a 100-120 V~: 6.3 A H 250 V. You should be able to find this in most places. If the fuse is not blown, then the unit must be sent in for servicing.

Roland ac 60 sudden loss of power. Is it the fuse?


If you mean it's completely dead, no lights or anything, then probably the fuse is blown. The question then becomes"what caused the fuse tio blow?".
If however, by loss of power you mean it's quiter but still producing sound, then the fuse is not blown.

Fuse blown on Europower PMP 3000. Where can I find a 10 Amp 250 V ceramic replacement fuse?


You don't need to use a ceramic fuse if one's not available. You can also use a glass cartridge fuse as well. Just be sure the rating is the same. Be aware, though, that fuses seldom blow on their own. Usually it's because something else has shorted. So don't be surprised if replacing the fuse only results in another blown fuse. Behringer stuff is notoriously cheap and under-protected, so by the time the fuse blows it's usually more trouble than it's worth trying to fix. But maybe you'll be lucky and it will be something simple. Good luck, and thanks for using Fixya!

Good evenin' pluged a dx626 to 220V with all as it was from stock. it light for a moment and from that time doesnt work. problem in fuse? please help


It could have blown the fuse. The fuse is a part of where the power cord plugs in behind a little cover.

Most of the electronics is fairly well protected. If fuse is blown, replace with identical size and try it once. If it blows again, some parts in the power supply are damaged and will require service.

I have a Lowery Genie 44, with a blown fuse


Do not change the fuse without finding out why it is blowen. If the glass is black DO NOT even think of changing it or you will cause more damage.
I think if you take out the fuse you will find the raring under the end caps of the fuse.
