Hi! My name isXXXXX am happy to help you with this! Please bear with me and be patient as sometimes these issues take a little bit of figuring out before we know what's wrong. If you could give me some more information it will be very helpful:

-What is the model number for the television? (this can be found on the back of the unit)
-How old is the unit?
- Do you have this problem while watching all different devices hooked to this television? (DVD player, cable, satellite, game console, etc.)

Please give me this information and I will be happy to assist you further.
Thank you,
Tim Nolan

No other problems with cable, etc.

Have you tried all inputs via the INPUT button on the Sony remote?
You get no picture on any of them?
Tim
Customer: replied 1 year ago.
I have and still no picture
Expert:  Tim Nolan replied 1 year ago.
What are all the options you had when using the INPUT button?

Tim
Customer: replied 1 year ago.
Actually it's Video Source and they are:
TV
HDMI 1 - 4
Video 1 and 2
Component 2
Expert:  Tim Nolan replied 1 year ago.
Is the cable box the only thing you have hooked to the tv?

Tim
Customer: replied 1 year ago.
cable box and router
Expert:  Tim Nolan replied 1 year ago.
How is the cable box hooked up?

The choices are:

Component cables: 5 wires between the tv and the device, these are color coded on the end and have a green, a blue, a red, a white, and another red cable

Composite cables: 3 wires between the tv and the device, these are color coded on the end and have a yellow, a white, and a red.

HDMI: 1 wire between the tv and the device, this is a single wire and looks like a computer plug on each end, similar to a large USB connector.

Coax: This is 1 wire between the tv and the device as well. This is the normal cable wire with the end the screws

HDMI
Expert:  Tim Nolan replied 1 year ago.
OK so we could have a problem with:

The HDMI input on the TV
The HDMI output on the cable box
Or a bad HDMI cable itself.

We are going to need to start testing to determine which one is bad.

Probably the easiest is to switch to a different HDMI port on the back of the tv to start with. Can you try this?

Tim
Customer: replied 1 year ago.
Sure
Expert:  Tim Nolan replied 1 year ago.
OK, let me know how it goes please.

Tim
Customer: replied 1 year ago.
There only is 1.
Expert:  Tim Nolan replied 1 year ago.
You have 4 HDMI ports on that tv. You only see the one you are using?

Tim
Customer: replied 1 year ago.
Wait. They are on the side. Hold on.
Expert:  Tim Nolan replied 1 year ago.
No problem, take your time.

Tim
Customer: replied 1 year ago.
The problem is the remote and the manual buttons will not let me scroll to select another source. It is stuck on TV as the source.
Expert:  Tim Nolan replied 1 year ago.
I thought you said you could go to all 4hdmi, compontent, composite and tv via the input button on the Sony remote?

Tim
Customer: replied 1 year ago.
Sorry. I can get the list of them on the screen but cannot scroll down.
Expert:  Tim Nolan replied 1 year ago.
Oh ok are they all ghosted (or greyed)out other than the TV option?

Tim
Customer: replied 1 year ago.
Nope. The only one that is grayed out is component 1
Expert:  Tim Nolan replied 1 year ago.
You are using the remote in the picture on the left at the link below right? And pushing the down arrow wont move the selection?

Tim
Customer: replied 1 year ago.
Correct
Expert:  Tim Nolan replied 1 year ago.
If you push the input button several times in a row, it wont cycle through the options either?

Tim
Customer: replied 1 year ago.
That worked! And got it to work by moving the cable to HDMI 2. Thank you!
Expert:  Tim Nolan replied 1 year ago.
Awesome! Glad its working. Please let me know if you need anything at all in the future.
