I'm sorry about the issue. No, you cannot display the password ***** the TV, but there are ways to get your Wi-Fi / wireless password.
What is the model of your Internet/wireless modem/router device?
Do you have a laptop/wireless computer that is currently able to connected via wireless? If so, does it have Windows xp, vista, or 7, 8, or Mac?
Please reply at the box below. Thank you.
