My tuner shows a green flashing light, the battery is new, even checked it with another one. No matter what i do it just shows a green flashing light. picking the strings for sounds makes no difference at all. It has been working great but now i don't know what to do. I use it all the time and really need, hope you can help me. thanks robby rowland [email protected]

Sounds like your tuner is locked. Try a different tuner, not cell phone based. Try a Quik Tune. Guitar Center carries them. Cheap.

You may have the tuner too far away from the guitar or the batteries may be going flat. Check to make sure that there is nothing blocking the microphone hole and that there is no other noises in the area which could be affecting what the tuner is hearing

my on board tuner used to do that. I just tried to tune the guitar normally and it usually worked after a couple of seconds. The tuner needs sound to work - it won't work without you playing any notes :)

Is the battery installed in correct polarity? If so- try rotate it in position to rub through potential corrosion.

Since it has a remote battery, it would not hurt to look at the installation to make sure no wires are broken. Especially the ground wire to the pickup.

It might also be a good idea to apply some contact cleaner to the output plug since it is in the power circuit. Cycle the plug in and out a few times to clean the contacts. Also some contact cleaner to the preamp controls would be useful.

Be aware some lubricants may contain silicone and that can interfere with wood finishes or repairs to the finish in the future.

That is working backwards from what it should be. I suspect a wiring error. Since this is a recent purchase, do NOT risk voiding your warranty. There isn't any real good documentation on the tuner.
I am not sure which tuner you have HOWEVER with one type, the FIRST press will turn on the tuner with the sound going out as well till the tuner goes off. The SECOND press silences the sound and is tuner only, the THIRD press turns off tuner and passes the sound. This is different than a lot of tuners and you will need to do three presses to restore sound instead of the usual two.

Hi
Simply turn the tuner on using the power button. Play an open string note close to the tuner (no more than about 1/2 metre away) - for instance the low E on string 6.
The built in microphone will pick up the sound and, if your guitar is reasonably close to being in tune the led light labelled 'E' will illuminate on the lower scale on the tuner along with one of the three other leds to indicate whether the note is flat (b), in tune (green) or sharp (#).
Due to harmonics any or all of these three leds may flash but it is the one that is on the most that matters.
Adjust the tuning peg until the green is on constantly when you play the string.
Move on to the next string
Note - if the string is more than a semitone sharp or flat a different light may flash (e.g if the low E string is 3/4 of a tone flat the D light will come on).
If you wish to tune your guitar to another instrument that is not at perfect pitch (and perhaps cannot be easily adjusted - like a pipe organ) you can use the calibrate button to adjust the setting of the tuner. This temporary recalibration will be lost when the tuner is turned off.

I have this same problem. I press the button to turn the tuner on and nothing happens except the arrows on screen flash alternately. There's also no sound from the output

i don't really know what instructions you expected, although you should have received something for the tuner and amp. I suspect that you are new to playing the guitar, as, I don't wish to sound disrespectful, you would know what to do! So first, and again I hope not to sound like I'm treating you like a dummy, plug the guitar into the tuner input. Or if It's a piezo tuner clamp it to your headstock. Most tuners are now automatic so it should pick up on the string you are striking.Repeatedly pluck the same string til the tuner changes colour, or flashes, or some other indication to tell you the string is at pitch. Repeat the above for all 6 strings.
Then plug the cable into the amp input, switch it on, and bugger about with the controls til you get a half decent sound. ( thats what the rest of us do).Don't expext too much from this package, it is budget level, but of quite good overall quality.hope this helps
