The brightness (backlight) of my nüvi 1440 screen is not steady but flickers randomly and rapidly. It does this only when the brightness is set to more than 30% and only for the first 5 or 10 minutes after switching on. Thereafter the screen brightness is steady, even when set to 100%. As if the screen has to warm up first. It does this in day as well as night mode. I tried tapping the screen, knocking the unit with "calibrated force", putting slight torsion (twist) on the housing, all having no effect.
I wiped the internal storage clean with RMPrepUSB, flashed new FW, updated with WebUpdater, cleared NV, loaded detailed maps, but still the screen flickers.
Considering what I have tried already, I'm assuming it is a hardware issue. Apart from replacing the screen, anyone having other suggestions to try first?
