Hi, new to this forum and would love some help! We received a 26" Sharp Aquos LC-26D6U as a gift a little less than a year and a half ago. Less than a year after we received it, it developed two apparently separate problems. Most annoyingly, it spontaneously turns off, stays off for a few seconds, and then turns back on. Sometimes it will do this a bunch of times in a row, turning off every minute or even every 10 seconds or so. Sometimes it will be just fine for a week and then start up again.
