Yamaha Electone MR-700T electronic keyboard / organ. When I turn it on a number of lights are flashing but it is not responsive. Has anyone experienced this?

You have a fault no one else has reported. There appears to be no reset procedure. Take it to a Yamaha Service Centre.

I have an electone organ that when turned on its all static nothing else

If you have speakers connected to it, disconnect them to see if the static stops. If there are no speakers clean the on / off switch and any volume controls with electronic switch cleaner.

I have a Yamaha FS 30 Organ it powers on but all the operation buttons do not respond and the sound coming from the keys are abrupt. Please, what could be responsible for this?

first, how old is this unit? according to this page https://en.wikipedia.org/wiki/List_of_Yamaha_products#Electone_(electronic_organs) they were built between 1983-1988. In other words, it's over 30 yrs old and it may have had some internal electronics finally die.

Go to the electone forum at electone.com and ask there.

Also the organ forum

When there, go into the home organ section.

This is likely in the power amp or the drivers for it.

The key to troubleshooting is a schematic. Try to procure one.

You MIGHT try using circuit cooler in the area of the power amps to isolate a bad component or cracked circuit board.
