Hi everyone,

Something to share, in the event any other users have these problems.

You can imagine my dismay to turn on my like-new POD XT Live, only to see the words "Invalid Code Error 01".  After turning it off and  on again, now the screen was simply blank.  Even more alarming was that after doing a search on the internet (and these forums) I found that I am not the only one with these problems.

When connected to my computer, Line6 Monkey would not recognize my XTL by USB, but strangely it would recognize it via MIDI to USB.  I was able to flash the firmware (according to Monkey).  Still, nothing from the XTL and only a blank screen.

These are my symptoms.  I could not stomach paying to have it repaired when it is in like-new shape and nothing unusual had happened to it.  I decided to open it up.

Here's where I have to add:

If your POD XTL is still under warranty, you should not do what I am about to describe.  Opening up of any electric device is dangerous and will void any warranty with Line 6. 

If you are at all hesitant, or you are not safety-minded do not open up your POD XT Live.  There is danger in any exposed electronic item - even when not plugged in - because great amounts of voltage are stored in harmless-looking capacitors.  This voltage can stay stored for a very long time, so don't become complacent thinking it is safe since the item has not been turned on for a week.  Furthermore, you risk additional damage to the unit.

With these points in mind, I searched the net and found a few posts describing taking the bottom off of the XTL.  I strongly suggest any interested parties to do the same. It involves taking off 8 screws along the bottom perimeter of the base and, depending on the year of your XTL, you may also have to remove the two screws found directly under the base of the volume pedal.  Lastly, remove the farthest left and right screws on the rear of the unit (the side where your cables go in).  Note one of these screws also holds the power cable lock.

Opening the POD up revealed a very impressive and tidy layout.  Using only one hand (not two to avoid grounding)  I held a small thin wooden dowel (do not use a metal rod or pen which can conduct electricity), and I firmly tapped any electrical components.  I did not hit the parts, just a firm couple of taps.  I tapped ICs, Chips, Caps, Resistors, and cable clips...basically anything that might have become loose or was not conducting properly.  This only took 2 minutes.  After that, I turned the POD over, carefully plugged in the adapter and turned it on.  It works perfectly now.  I think you can imagine how relieved I was!

The reason I am sharing this is to offer an additional view on the Blank Screen problem as well as the Error Code 01 problem.  It could be, for some users, that some parts of the POD XTL need to be seated a bit.

Please be safe and consider this instance if you have a similar problem with your POD XT Live.
