The sound quit working while playing the

This looks like an overhaeting problem at fiirst glance. This shouldn't happen however. Have you had it long before it started failing? Doe it happen every time you play it, and also at low volume? If so, all I can think of is having it checked out by a technician.

All sound equipment has to operate without overloads in any given place. The power source should always be examined at commercial gigs and worked out with other performers along with management. The only fix is to do these checks up front and make safe arrangements.

Sounds to be getting old and has some dried out filter capacitors that need replacing.

It sounds like you have a part overheating and failing, then cooling off and starting again. i would take it into the nearest Yamaha repair facility or contact your local authorized repair to come take a look before it goes out of warranty.

The same thing just happened to me but without any shorting out sound. And the sound came back after I played around with turning things on and off and unplugging and plugging things in again. Not at all god during a gig. Anybody have a solution or diagnosis for this problem?

is there power to it? does sound come out of it? if not it could be fried or about to fry. Behringer makes low end products, which tend to break fast. if you dont have any sound or lights chances are its unfixable

Just because the voves are lit doesn't mean there is the high voltage power to the valves.

ALSO the smaller valves have TWO heaters in them and if one half has burned out that would cause the symptom. Check if the smaller 12AX7/12AT7 types all have two heaters burning. Verify that the standby switch has not gotten bumped off.

I have Tyro I and II myself.

If somehow the registration is being bumped up or down during playing that would do it. VERIFY all the settings for the external pedal inputs regarding levels and function. Some of these can be set to do more than one thing. As a result, a pedal connected to the three jacks MIGHT be used for sustain and also triggering a step in registration number that is unwanted.

One needs to analyze the state of the unit when this happens...this should be possible UNLESS the whole thing including the data entry and display is freezing.

With the thousands of internal settings that are possible, it will be hard for us to give a definitive answer.

If you can afford to lose user created stuff, do a complete factory reset of the unit.

I have read that the problem is in the FX send/return jacks which oxidize if not used much. All you have to do, apparently, is ram a jack plug in and out a bunch of times. This breaks up the oxidation, and allows the amp to work properly again.

If this is happening on all keys it sounds like your aftertouch is not set right. You may not have gotten the key assembly lined up quite right also. Check these first.
