I bough a line 6 spider iv 75 w, in less then 1 month, and when i was playing suddenly the sound went off,  i restarted it and still no sound, i activate the tuning option it get no signal by guitar, the lights are still on, i can still change the presets but i got no sound,
Its very frustrating to have a 1 month new item and having problems like this !!!!

Have you tried a factory reset?  With the amp off, hold the 'A' button in and turn on the power, keep the button pressed in for about 5 seconds. 

 

Is there any sound from the headphones jack (you would have to plug in headphones)?  Have you tried a different guitar and input cable?

I am facing the same problem with a spider iv 30 w. My friend was playing and suddenly ... No sound... Nothing working... You can and move any knob and nothing happens...

According to some videos from YouTube maybe the problem is caused by a overheating of the processor of the amp, so you should use some pieces or fan etc to dissipate the heat.

But i am not sure about it when talking about the IV series...

Hey Leonardo, no need to post the same thing in multiple old threads - start a new one, if you need to.

After 'cooling off' does the amp work again?  If so, then it may be a bad solder joint on the circuit board (no way for you to find it, though).  If not, then it could be an internal fuse.

Could be problem with a jack contact, if it fails, it can trip the power amp mute. Or, the

power amp chips have failed. 

 

Should be dealt with by a Line 6 authorized service center who knows the product. Not a self repair sort of thing.

Same here, turned on like normal. I always noticed turning on the the amp would do a brief volume spike then mute. With or without the FBV MK II Shortboard attached.

Except now, no sound at all from guitar input. It appears many are facing this problem. One would think there would be a response after so many times of this occurring for so many years now. Really disappointed by modeling amps. It takes a lot of time to setup things for a reliable jam rig. Makes me consider going back to straight solid state amps. I love the Tap loop function and being able to turn FX on and off with the FBV ShortBoard Mk II. Never could get the Wah to work right. I think the activation switch in the ShortBoard is bad.

I'm going to try the Software route and see if anything repairs. But I doubt it. It seems like a system board failure and fairly common to these amps by design. Otherwise we would see answers here. I saw a video of a guy hot wiring to the CD input so that's a major warning to me about board failures. This amp has not been stressed in the least. The jack has not been abused in any way. I'm a veteran player and take a great deal of care. I know how to care for things. Some of my guitars are 35 years old. My 1990 Fender M80 Twin Chorus works great. It's just too loud for home practice.

Had a similar issue with my 15 watt spider IV, POD X3 Live.  Can't tell you exactly what I was doing when it went out, just that it went from working to not working.... It was extremely muted,   Likely what psarkissan described.  Couldn't get anything to work with the amp and ended up doing a factory reset and that resolve the issue.

 

 How do you soft reset (spider IV 15)?   Or is there a specific way to 6 the mute issue other than hard reset?

 

 Since I the problem, I've changed how wine turn the amp on.   Master volume gets turned to the lowest position, anything plugging into the amp is at its lowest position then I turn the amp off.   Turn the amp on but 1st everything is in its lowest volume position... Haven't had a problem since.

Thanks Psarkissian. Can I just send rack portion of it and save myself the case and speaker weight shipping?

Or can I just physically take it to authorized service center nearby? I'd like the Short Board serviced too.

Either one. Log a support ticket and they can go over the options with you.

Hold down  "A" during power up, wait for it to flash twice, then let go of "A".

Okay, I updated the amp to the 2.0 file from original. The mute went away. Amp is working.

Updated from the Monkey interface.

Trying to edit using Line 6 Edit to change my presets names. Interface saved the file and bundle to PC.

When I try to send updates to the amp though it just stays at 0% receiving. Amp user presets names remain unchanged.

What am I doing wrong? I restarted amp and PC. Reconnected using the Line 6 Edit software. Edits now send to amplifier.

Amp mute failures went away. I can now play the amp fine again. Thank you.

Monkey is for updating firmware, not editing.

Go to the Downloads page and get the Spider Edit.
