my REV 7 if broken?? PLEASE HELP!?

smalltownjon · 5th November 2006, 04:23 AM

All my yamah REV 7 will display is this message. I just got it and have never used it before. Is there some sort of Factorly reset i can do? Or do i need to get it out of edit mode or something? None of the buttons seem to respond. thanks for looking...

That's the initial startup "message" that I see on mine when I turn it on - then it flips to the particular patch that was last used. Sorry I can't be of more help than that. I don't have a manual handy.

It just gets stuck there. I think that what it could be is the internal battery for the memory may be dead. and i might have to find a replacement. I wonder how hard that would be. Because int he manual it says that they should be replaced every 5 years. I'm sure this unit is older than that.

Does this sound like what it could be? Do you know where i could get a battery?

I think that the battery only stores settings you create , but I could be wrong.

I do know this...
There are certian chips in the REV7 that ARE NOT available any longer.
I can't recall the symptoms they show when one of those chips fails.
If the problem involves any of those chips then it is trash or rack filler.

About seven years ago I had an SPX90 that had a bad power supply.
Yamaha informed me that they didn't have any more of them.
I also had a REV7 that was un-repairable (it was the chips I mention.)
I took the power supply from the REV7 and wedged it into the SPX90.
It was essentially the same supply in both, but I had to rig up a remote on/off switch once I put it in the SPX90.
The REV7 went in the dumpster!

My good friend has a REV7 that is dead and he wants me to look at it.

Generally when REV7s are dead they are DEAD.

Sorry to be the bearer of bad news!
