I have a Sharp LC-c52700un Aquos LED HDTV, hooked to a DISH box thru a HDMI cable and have a BOSE 321 also plugged in for sound.when turning the Tv on most always and usually first thing in the morning the picture will come on and then for about 5 seconds green vertical lines appear with a very loud static noise.The picture goes out(blue light goes out) and then it comes back on and no problems.I'm not sure if the problem is with the TV,or DISH,or I have the settings wrong. Any input would be helpful Thanks!
