I turn to my Yam psr2000 many times a day and noodle around on it or play. Would it best to turn it on an leave it on or turn it off/on each time?

I keep my kb switch on and turn off and on with separate multiple outlet switch. At very least,it is cheaper to change oulets than an internal switch.

Personally I think it would be better to turn it off and on each time. I think that the electronics wear out more when the instrument is turned on than when it's not.

For PSR-3000 owners (like myself): don't keep it turned on too long without playing it, it's not too good for the display. Mine loses its brightness after a while. When I turn it off for a while, it's back to normal, but I don't think that it's very good for the display.

My studio equipment is ON when I'm around, what means from 17:00 till 01:00 almost every day.
Displays losing brightness/contrast seem to 'warm up' while the instruments internal temps get a little higher. You should be able to re-adjust the contrast-poti during operation.

Modern components don't lose quality while on, as long as they are not electronic-tubes. In fact most defects occur while switching equipment to ON.

Normally, when you power up electronics (like a TV, PC, Video, DVD Player) it's harmful because the electronics get a "burst" since the transformers in them are not yet at their default when first powered up.

In the case of the PSR's however, the transformer stays on (that is, if you leave it in the wall outlet) and the ON/OFF switch on the board only allows regulated DC to flow through, which makes it way easier on the electronics.

Now as far as the Tyros goes, I believe the power regulator is inside, so I would presume the power switch there is on the AC side, which is more harmful to the electronics each time you power on.

Have a nice day

When I was in my late teens, girls turned me on and off a lot. It wore me out.

Didn't wear me out as a teen. Wears me out NOW.

Quit messing with those teenage girls, Don.

Eddie

just to give my 2 cents...firstly the electronics dont get a "hit" or surge...they are powered by a regulated DC voltage rail post transformer...secondly electronic components dont "wear out" they either work or dont work.there is no gradual downgrading of their performance , as long as the normal operating conditions always apply ie no strange or unusual things happen.

peace, out

If you do turn on and off, it is better to use an external switch, because the mechanics of the switch can wear out or break.

I always keep my keyboard switch on and turn on and off externally.
