I have sony bravia model kdl-46ex500. It went off after lightning strike. When I try to power it back on it will come on long

Your post seems to be a bit incomplete: Are you saying that the TV does come on after a long time?

Have you tried plugging it into other outlets on a different circuit. Do other devices have a problem using the current outlet?

Are there any surge protectors or power bars in use with the TV?

Please add some additional details. Thanks.
