Audio but no picture after TV has been off awhile?

When I turn on my TV after it has been off 3-4 hours, it takes 15-20 minutes for the picture to come on. I have audio but the screen goes black and then doesn’t appear for 15-20 minutes as though it has to warm up. I can sometimes see color around the edges. I never have any problems with the picture other than when turning it on.

ANSWERS:

greener_bs  could be a power board or main board issue. Vizio is known for poor soldering connections on their ribbon cable connectors as well as other components. Colder solder issues are the once that usually are responsible for this. The connection closes after the component heat up etc. Post some good pictures of your boards with your question so that we can see what you see. Use this guide Adding images to an existing question for that. Possibly capacitor issue, however those usually manifest in the opposite way. It is also possible that this is a MOSFET issue etc.
