Green Screen

Talman — Fri, 09 Jan 2026 21:43:56 GMT

I have been having issues with my TV losing internet connection there is no pattern to it sometimes I have to reconnect two or three days in a row and sometimes I can go three days before I have to reconnect.

However now I am getting a green screen on occasions, which is rectified when I reset the box.

I have been in touch on chat as requested because a test found a fault with my service. I am not sure if this is all connected. The young lady had me try several things and at her request I reset the box.

Occasionally the internet connection drops for my pc and I have to restart it.

So I am not sure if this is being caused by a router fault, a dodgy box or something else! Any suggestions / help would be appreciated!

Many thanks.

Which tv box do you have so we can offer advice?

Have you tried changing the HDMI cable as this can cause a coloured screen if faulty or not seated correctly.

Hi

Thanks for your response! I have this box. I have checked all the the connections, but will try another HDMI cable.

Best wishes Dave.

@Talman thanks for that. Are you using the HDMI cable supplied with the box or one you already had? The box really needs a 4k rated cable and some older cables are not capable of transmitting the full signal from the box to the TV. The supplied cable meets the requirement.

even so, mine sometimes starts and has a purple tinge to the picture, which is easily resolved by turning the box off then on again.

When you say a green screen is it a total green screen with no picture or sound, or the picture is there but coloured green?

If a new cable does not help then you will need to try a factory reset of the box. You will then need to log into your apps again as these too will be reset.

Details can be found here.

Please let us know how you get on.

Thank you.

It is the one that came with the box I have an older one, which I had with a previous box but swapped it out.

There is sound, no picture and a completely green screen!

I will try the factory reset and see if things improve.

Thanks for the help.

Best wishes Dave.

Hi Phili

Unfortunately not! I have also changed the HDMI for a brand new minimum 4 k rated cable.

Any further help or advice would be appreciated.

Best wishes Dave.

Sorry for the delay in response, we have had a family bereavement, so things have been a little fraught.

I am home most evenings ( alternate Tuesdays I play chess ) and I am generally home every afternoon. I have recently been in touch via chat and they checked various things with me and we also reset the box at that time.

Best wishes Dave.
