No Sound or beeps

Could be a wholes series of things. Does it power on? Does your amp power on? Could be the mains transformer, could be faulty leads, are your guitar pickups active? In which case the battery for the pickups require replacing. Have you checked the volume on the guitar, fx unit and amp?

It sounds like a defective/incorrect AC-to-DC adapter may have caused your problem. These adapter come with different output voltages, AC or DC output and different amperage ratings. AC-to-DC adapters list the polarity of the DC voltage as it relates to the DC power plug and you must match both the devices voltage and power requirements. As for the amp...not working on batteries either, I would suspect output transistors or IC.

Have you checked the cables? If that doesn't fix it, you probably have a loose connection inside between the "mixer" unit and "amp" unit

replace the 22xt diapraghm

The amplifier takes a bit of time to come to DC balance and same thing happens as power goes down. Some fancier units will have a relay to disable speaker until balance occurs, but this one does not. As long as the cone centers within a couple seconds it will not cause a long term problem.

Holding the page up and down buttons while powering on supposedly resets it. I have no sound except demos, but no lights showing like yours, and williams tech support said to reset that way but it didn't seem to do anything. Good luck hope this helps!

To troubleshoot the problem start with the bit that is working - the left speaker.

1. Unplug the input leads on the back of the left speaker and swap them round.
2. If sound now comes out of right speaker and not the left the problem is with your sound source (computer, IPOD or whatever) or the connecting cable is faulty.
3. If there is still no sound from the right speaker try turning the volume control knob up and down quickly several times - does this produce any sound from the right speaker? Sometimes the electrical contacts get dirty and this can help clean them.
4. Turn the speakers off using the volume control knob. Disconnect the speaker wire for the right speaker from the OUTPUT on the left speaker (push the red and black tabs downwards and gently pull the wires out. Find a small 1.5 volt battery (an AA or AAA size will do nicely) and touch the bare ends of the speaker wire briefly on the battery terminals. If you hear a slight crackling sound the wire and the speaker are okay and the problem is in the amplifier, which will need repair or replacement - not a job for an amateur.
5. If you don't get any sound from the battery test find another piece of speaker wire (any piece of 2 core cable with bare ends will do for testing) and repeat the battery test. If you get sound then replace the speaker wire. If not remove the speaker wire again and go to next step.
6. Lay the speaker face downwards and carefully unscrew the back panel (don't do this if it is still under manufacturers warranty - take it back for repair or replacement). Lift the back panel off carefully and slowly taking care not to pull the connecting wires inside the cabinet, which will probably be quite short. You may have to settle for just rotating the back panel slightly so that you can see inside if the wires are too short to do otherwise.
7. Use sticky tape to tightly attach the bare ends of the speaker wires to the terminals of the battery. Touch the loose ends of the speaker wires on the two metal terminals where the internal wires are joined onto the back of the big loudspeaker cone. If this produces a crackling sound it is the internal wiring in the cabinet that needs re-soldering. Otherwise the loudspeaker unit has failed and will need replacement.

If you just bought the guitar, take it back. Taylor has good warranty programs, take it back to the dealer. You may have a bad connection inside where the saddle pick up plugs into the graphic preamp, the fact that you hear a sound when you put the battery in or out indicates very little. You may have a bad preamp, like I said, if its new, don't wait get it back to the dealer or contact Taylor.

There should be a headphone jack... try headphones first...

If no sound from the phones with the volume control up, the unit MAY have lost settings due to depleted memory battery.

Look on the web for "factory reset" procedure for the W7.

Some of the Alesis products have a setup and data memory backed up by a battery. It is POSSIBLE that your battery expired and took the sound memory with it.

Investigate if you have a battery in yours (buried in the guts) and check the voltage. It should be above about 3 volts.

If it is below that, replace the battery and find another unit to clone the data from.
