Panasonic 55" TV "HELP PLEASE"
I have a Panasonic TV model TC55CX420U and it will not turn on and there is no sound either. When I turn it on, with the remote or the TV button, the red light just comes on steady. One thing it does, back of set taken off, when I turn it on the red light turns on and in about 15 to 20 seconds I see light blink one time through the holes in the back panel, picture #2. I have replaced the power supply board but it does the same thing, picture #1. There are other boards but I really don't know the names, picture #3. Hope someone can help because it is the only smart TV in the house. Hope all this information helps. See images
