I am not a master of Photoshop, but i like the way masters create things by using the creative minds. I am learner of Photoshop, i love to different experiments in Photoshop. Today i decided to post a tutorial on making a 3D TV. Hope you like it, you can learn so many things in this tutorials which may help you in further use of Photoshop. Below is the final image after putting that TV in TV room(wallpaper). :)

First create a gradient with any desired color, its not necessary so you can use a simple black background.

Now create a rectangle shape and go to Layer > Layer Style > Blending Options, and use the Bevel and Emboss as shown in image.


then put rounded rectangle shape (U) in it as shown below.

After creating that rounded rectangle shape (U), go to Blending option and set the shown settings to the rounded rectangle shape.

Now you must have a suitable structure of your TV. Now put buttons by creating four or five rounded rectangle shapes (U), and put this Blending option on them.

Now you will get this image. Now Lets create stand of the TV, because a TV can't stand without its stand. :D
Put a circle by using Ellipse Tool (U) below the TV layer, and set the settings shown in the image. Then put a suitable Background in it.

Now create a new layer by pressing "CTRL+Shift+N" and select the layer as shown in the Screenshot by  "Rectangular Marquee Tool". Now press right click and select "Transform Selection".

Now Hol CTRL+Click+drag to give it the shape shown below, as we did it in previous tutorial of Making shadow using photoshop. You will get selection as shown below.

Now put Gradient in the selected area, and decrease the opacity of the layer



Now you are done, put this TV in a TV room an enjoy watching it... :D
