I just purchased a POD HD500X last week. It only has a few hours of use and I am losing half of the LCD screen randomly. All of the firmware is up-to-date using Line6 Monkey. I have submitted a ticket about it, but I'm not sure how long it might be before a response and can't do much once I am back on shift at work. I can probably just bring it back to where I purchased it to get a replacement, so I was hoping I might be able to get a little more insight a little quicker here so I don't have to wait another week. I was just curious if this is a known issue or not. I haven't been able to find anything about it that is similar to my situation. I can't force it to happen and it will reset if I unplug the unit and let it discharge before plugging it back in. Any help or suggestions are greatly appreciated.
