I'm sorry you're having trouble with it, I need more info to troubleshoot the problem.
- What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?

Ask Your Own TV Question
Customer reply replied 8 months ago
i have a cable box attached that is it
Customer reply replied 8 months ago
Ouch and a wireless adapter
TV Technician: Shahid, Technician replied 8 months ago

OK, can you please try another video source such as Bluray player or gaming console into HDMI input of TV?

This will verify the TV.

Customer reply replied 8 months ago
Yet again f I plug this same cable hdmi into a different tv it works there
TV Technician: Shahid, Technician replied 8 months ago

Nice, that means TV itself is fine and problem would be within cable box.

- Have you tried to disconnect TV and cable box power cords from power outlet for 10 minutes to reset, replug back in, let cable box reboot that may take several minutes and check?
If not yet, please try it now and reply back with the result

It is still not working
TV Technician: Shahid, Technician replied 8 months ago

This is odd, did you reboot TV and cable box exactly as requested in previous reply?

Ask Your Own TV Question
Customer reply replied 8 months ago
I did. I unplugged both from power and from each other for 10 mins
TV Technician: Shahid, Technician replied 8 months ago

OK, does the same cable box work on another TV?

Also, can you try a different HDMI cord between TV and cable box?

Ask Your Own TV Question
Customer reply replied 8 months ago
I connect the same cable box with the same cord to another tv and it works
Customer reply replied 8 months ago
I have tried a different cord and that made no difference
TV Technician: Shahid, Technician replied 8 months ago

This is odd, let me invite other experts to look into this issue so reposting this question for other experts.

Hi harry yes I still need help
TV Technician: Harry, Customer Service replied 8 months ago

I would like to summarize what is going on:

The HDMI ports work if you use a Firestick or streaming device. If you use the HDMI cable, it won't work but if you take that same cable and plug it into another TV, it works there.

Does that sound accurate?

Ask Your Own TV Question
Customer reply replied 8 months ago
that is correct
TV Technician: Harry, Customer Service replied 8 months ago

Now if you take that same device that won't work on the TV and connect it to the other TV, does it work?

Ask Your Own TV Question
Customer reply replied 8 months ago
I have a cable box with an hdmi cable. I attach the hdmi cable to a different tv and it works. I attach it to this tv and it doesn’t work. The source is not able to detect the connection
TV Technician: Harry, Customer Service replied 8 months ago

Yes, I understand the cable works on another TV.

Does that cable box work on another TV?

Ask Your Own TV Question
TV Technician: Harry, Customer Service replied 8 months ago

If you attach different HDMI cables to that TV, does it recognize any of them?

Ask Your Own TV Question
Customer reply replied 8 months ago
I’ve tried a different cable and it still doesn’t work.

Have you tried a factory reset yet?

Ask Your Own TV Question
Customer reply replied 8 months ago
found online that I can hit mute-1-8-2-power and get to the factory reset option so tried that but did not work. I also did a software upgrade and no diff
TV Technician: Harry, Customer Service replied 8 months ago

I am stumped on this one. I would say that the ports are faulty but you said it works with your firestick without any issues.

Have you tried all HDMI ports?

Ask Your Own TV Question
Customer reply replied 8 months ago
i have tried all the HDMI ports
TV Technician: Harry, Customer Service replied 8 months ago

I am completely out of ideas on this one.

How old is the TV?

Ask Your Own TV Question
Customer reply replied 8 months ago
7 years old
TV Technician: Harry, Customer Service replied 8 months ago

To be honest, I am stumped at this point.

I would recommend having someone locally come out to take a look at it because there are not anymore suggestions that I could try.
