I have a Ms 908s that i purchase about 4 weeks ago thats giving me a problem now.The 3rd day i was scanning a vehicle and the screen went white,so i power off and back on and the screen start rolling like them old black/wht. TVs.
If it was sitting on seat in a hot car with the Summer Sun beating down and temperature of unit reached 120 degrees Fahrenheit or more , turn the unit off and let it cool down and don't start it back up until is cool to the touch.
