Welding on the frame is a likely cause. The voltage spikes can damage the control boards. Since it's cooling and diagnostics show no errors, try disconnecting the 12V for a few minutes to reset it. If the display keeps scrolling, the front optical board may have been affected. The 2118 optical board is discontinued, but the 637082 power board (rear board) is in stock if that's the part that was damaged.
