I have a 55PFL560/F7 will not turn on

sheilrdr you are not telling us what your TV does. If you get no light anywhere, check the power cord and your outlet. Make sure you have power going into the TV. After that, you'll have to remove the back cover and check the fuse on the power board. See if it is blown. It might help if you can post some good pictures of your boards and the interconnect cables, with your QUESTION. That way we can see what you see. Edit your QUESTION and follow this guide Bilder zu einer vorhandenen Frage hinzufügen

Also, please verify your TV model number for us. Just to make sure it is correct.
