Recently, a small squiggly line has appeared on the display screen of my Legacy Cab-2 remote. It can be seen in the attached photos, just below the engine RPM display bar, above and between the ACC and RTE icons. I first noticed it last week, and after being shutdown and restarted numerous times over the weekend it is still there. No extreme external forces such as dropping or bumping has occurred to either the remote or the screen. Notice that it is present with or without the remote being turned on, and even when the batteries are removed, yet the line appears to be the same as lines on the display when it is energized.
The complete Legacy System was purchased new 12/31/18 from an authorized Lionel dealer. I fear it needs to be sent back to Lionel, but after reading and hearing many troubling comments regarding their customer service, recent repairs and quality, I am hesitant to contact them, and only desire to do so as a last resort. Any comments or suggestions on other options (if any) on how to possibly correct the situation would be appreciated.
