Thread: Blank Screen and Buzzing Noise

I have 3 day old HP DV6t-Quad and every once in a while the display will suddenly go blank and a loud buzzing racket will emit from the speakers. If I turn it off physically and rotate it
back on, the problem will go away until the next panic assault. I was wondering if anyone
had some idea what the problem was, and how to fix it.

Please you don’t touch it because 3 days old. Replaced it.
