Just checked, I merely get a blank screen on my TV, no theme.
Let me try and help as the receiver Dinesh has was bought from me.
The theme Dinesh is probably talking about is the Pioneer logo that will float around the screen when there is no signal. I had disabled this.
Dinesh, if you have not reset the receiver, then all the fancy screen saver stuff is disabled. All you will get is a blank screen.
On the subject of inputs, let me explain, whatever shown on the display should match the terminal label behind the receiver. Selecting TV will not do anything unless you have something connected to the HDMI input behind. To my knowledge there us no HDMI input labeled TV behind the receiver.
The way I connected it or set it up in the software , Set Top Box went into CBL/SAT input behind the receiver, Blu Ray disc player into BD input. CBL/SAT is set as the pass through HDMI feed. When the receiver is in Stand By power, you can watch TV without powering on the receiver. When you turn the input selector to BD, then you can spin Blu Ray disc. I must add that you can play a Blu Ray disc without having the receiver ON (Should be in Stand By). It is possible to press BD on the remote and switch the HDMI Pass through without actually turning on the receiver. This will temporarily switch the HDMI Pass through while on Stand By from CBL/SAT to BD or any HDMI input for that matter. It won't display the selected input on the front panel as the receiver is on Standy By. However; a red lamp on the right will light up indicating a HDMI signal. This confirms HDMI is passing through.
The only time I recall seeing TV displayed on the receiver's front panel is when I play content from a hard drive connected to the TV's USB input or when streaming content from Netflix. This is audio return channel or ARC in operation. TV is automatically displayed on the receiver display panel when the receiver detects an audio feed coming from the TV. Not otherwise.
HDMI ARC needs to be set up on the TV. Most TV's do not have this set to ON by Default. Only one HDMI terminal behind the TV will support HDMI. You should connect to this from the receiver's HDMI Output terminal. With the receiver ON and TV in Stand By, when you turn On the TV, the receiver's display with show TV. This means it has detected your TV via ARC.
About HDMI and ARC. This receiver is a little slow to hand shake for ARC. If you have completely powered off the receiver from the mains supply and then you put the power back on, it takes up to 2 minutes for the receiver to hand shake or communicate with an ARC capable device. In this time, do not turn on the receiver. Off course, none of this is an issue if all your AV gear is left on stand by and never switched off at the mains, ever.
I have not re labeled any of the HDMI inputs.
No user manual was supplied with this AV receiver other than a Quick Set Guide. When I got stuck with something, I downloaded the online PDF. It helps to print this and keep handy.
