What do you mean by, wd my cloud tv? Is Google Wi-Fi your Internet Service Provider? You say you have a Sony TV XBR-905. Does it have a browser on the TV?
I have a Sony Bravia, Smart TV, 4K etc. If I want to view things from my WD MY CLOUDS I would select Music to see my music, Photos to see my pictures etc. If I want to see the Dashboard I can enter the address in the browser.
I am going to add some example images from my Sony Bravia TV. Hope this will help. Click on, tap, or activate images to enlarge them.
Photo One, I used the address for my My Cloud in the Browser on my TV.
Photo Two, I sign in and open the Dashboard
Photo Three, Using my apps on my Sony TV I can choose what I want to view or use the browser.
Photo Four, After selecting Music and opening it this is what I see.
Photo Five, signing in by way of mycloud.com using the browser on my TV.
Photo Six, I select my device.
Photo Seven, after signing in I can view whats on my WD MY CLOUD.
