Recently, when my RV12 Master switch is turned on, the Skyview blinks twice or 3 times with a screen of colored vertical lines, then the vertical lines remain, - no buttons or knobs have any effect while it is in this condition. When booting up using the backup battery, the same thing happens. On one or two previous occasions I had noticed the battery voltage display showed 1.1 volts. However, on local display setup; BATT backup status; showed 10.7 volts, test result pass greater than 45 minutes. Last test 11/24/16. Has anyone had a similar problem? Or know of any cause or cure? Thanks Dean
