Switch Alpha 12 -- screen glitches, dancing lines on righthand, and glitch freeze fade to black
I've only had my Switch Alpha 12 for a few months. Since I first got it there've been intermittent glitches that appear sometimes on the righthand side of the screen, like little scanlines dancing around. More recently sometimes the screen like freeze half-dark with scanlines like a bad digital photocopy and fade to black, and a clicking sound comes out of the top righthand side of the monitor. I have to press the power button to turn if off and back on to get the screen working again.
How can I resolve these screen glitching issues? The freeze-fading to black glitch is more than annoying, and is driving me crazy.
