Screen goes slowly dimmer until almost black

Lucyboo27 — Wed, 02 Aug 2023 06:28:01 GMT

This morning I turned on the Tv and the screen was fine for a few seconds then went dimmer and dimmer until almost black. When I switch to normal Tv or apps (not within Sky) it's completely fine. Any ideas?

@Lucyboo27 are you using the HDMI cable provided by SKY to connect the SKYQ box to your TV?

If not you may have a faulty HDMI cable, or it may be too long, and needs to be a shorter one?

I'm sure someone else mentioned they were having a very similar problem with an Amazon FireTV. It sounds like there might be an issue with how the FireTV OS reads HDMI input signals.

What video resolution is your Q box set to output? Is it 2160P 8bit or 10bit?

We are currently having this issue did you figure out what was causing it? We have tried the usual things are restarted the sky box, changed the hdmi port and it still isn't making a difference our hdmi is the one provided by sky too it was fine this afternoon but this evening it's decided to stop working. We have had sky in for 2.5 years nearly and had the TV we have now for about 9 months with no issues. @Lucyboo27

Did you find out what was the problem or how to fix it? Ours has just randomly started doing it this afternoon! Weve tried everything.

We have the same problem. We have checked HDMI and reset box and still have the same problem. Please help with any other solutions.

We hard reset the TV to factory settings and this fixed the issue. So may not be a sky related issue but a tv related one.

More or less bang on the nail @StuM2585 @ . OLED tv's have asbl built in to protect the screen by automatically reducing the peak brightness, especiallyif there is a static picture on screen. On certain TV'S this can be adjusted but on some it is too aggressive. LG released a firmware recently to reduce the agressive dimming with some of their models, so it might be worth having a look to see if there is one for yours Lucy, if you have an LG that is. If you could post up your make and model I may be able to help further

I have a Toshiba QLED and mine has only started doing this today. It's only on standard picture mode though, when I switch to sport or film it's fine. Can't understand it at all.
