I have a Panasonic TC-P42S30 that wont turn on. I haven't used it in about 3 or 4 weeks, during that time there was a thunderstorm that caused the power to surge. I do not believe it is in shutdown mode because the lights do not blink at all after being unplugged for a few minutes and replugged in. I have already tried a different power cable and bypassing my powerstrip. All of my other electronics that are plugged into the powerstrip/outlet are working correctly.
