I need to update my payment method on my Apple TV device. I do not have an Apple TV or an iphone. I have an Android phone and an LG TV. I purchased the Apple device for my LG TV. I can't seem to get to itunes to update my payment method.

Hey ceskeen1951,

Your payment method can be updated with an iOS or Mac device.

"Change your payment method on your Android device or Google Chromebook

You can edit your payment information on an Android device or Chromebook, but doing so will remove all payment methods except your primary method from your Apple ID and from other devices that you use with your Apple ID. To avoid this, use iTunes to update your payment information.

1. Open the Apple Music app on your Android or Chromebook device. 
2. Tap the menu button  in the upper-right corner.
3. Tap Account.
4. Tap Payment Information.
5. Change or remove your information. To remove the payment method, select None.
6. Make sure that your name and billing address exactly match the information on file with your financial institution. Then tap Done."

You can also change your payment method this way as well:

"Change your payment method at tv.apple.com

1. Go to tv.apple.com and sign in with your Apple ID. 
2. Tap or click the account button  at the top of the screen.
3. Choose Settings from the menu that appears.
4. Under "Payment Type," tap or click Edit.

If you have multiple payment methods on file, you can't edit your payment information at tv.apple.com."

Best!
