Are There Any Known Problmes With The Hdmi Ports, No Signal

When you turn on the TV you get a no signal message. You can switch the HDMI port # and change the channel and eventually you can get a digital signal. This problem started about 1 month ago but was not consistent. It now happens every time you turn on the TV.
