I have a Panasonic TC-60PS34 60" plasma, built 5/2011. Periodically getting white screen (like looking through cheesecloth), with sound, when turning on. Turn off and on a few times and it finally works normally. Tried cleaning back, changing cables and inputs, unplugging unit, etc. Seems to be happening more often and harder to get it to work. I did notice that it usually clicks when turned on (red light comes on, no flashing) and clicks when I turn it off. When I turn it on and get a white screen, I notice that it does not click. When it does click when I turn it on, it seems to work normally. Any help would be appreciated.
