Welcome to JustAnswer, an independent support, pay per question website
Sorry to hear that you're having trouble with this and I'll do my best to help but need the following info to troubleshoot the problem
- Could you please get me the complete model number written on back cover or side panel of the TV?

- What video devices/ sources (such as cable box DVD player etc) are connected to the TV and does the problem occur on all video input sources?

The TV i'm trying to connect the Chromecast to is a Sanyo Dp42740. The problem does occur on all HDMI ports. I have a Cable Box connected in one hdmi port.
TV Technician: Shahid, Technician replied 1 month ago

Thanks for the info

- Just to clarify, you get cable box picture via HDMI on the TV but ChromeCast doesn't work on any HDMI input of the TV, is this correct?

Ask Your Own TV Question
Customer reply replied 1 month ago
this is correct. However, to watch TV, I don't go to a HDMI input, I go to a input called "video".
TV Technician: Shahid, Technician replied 1 month ago

ah OK, Video input is a different one, thanks for the additioanl info

- Can you connect the ChromeCast to a different TV, if available nearby, as a test to verify the ChromeCast device?

I normally use the chromecast for my bedroom TV and it works fine.
Customer reply replied 1 month ago
Also, I was mistaken about the cable box being through a HDMI port. My father has set up a new way recently so that it no longer has to go through the HDMI port. So there is no other HDMI ports being taken up besides the chromecast.
TV Technician: Shahid, Technician replied 1 month ago

OK, how do you provide power to ChromeCast?

Using a separate power adapter or USB port on the TV?

Ask Your Own TV Question
Customer reply replied 1 month ago
I used both. On my other TV, I can just use the USB port on the TV. I tried both USB port on TV and plugging it into the wall.
TV Technician: Shahid, Technician replied 1 month ago

OK, when pushing Input button do you see both HDMI inputs listed on input source list and are you able to select them?

Ask Your Own TV Question
Customer reply replied 1 month ago
Both are visible. They always are no matter if something is in the port or not.
Customer reply replied 1 month ago
I was just told by my father that the HDMI ports haven't been working recently at all, for any device.
TV Technician: Shahid, Technician replied 1 month ago

OK, following troubleshooting step should be tried that might help

- Have you tried to disconnect TV power cord from the power outlet for 10 minutes to reset, replug back in and check?
If not yet, please try it now and reply back with the result
