My Samsung 4k 55 inch TV randomly turned into a negative inverted color. I tried to reset settings and it didn't work. Is there anything else I can do.

Hello, I have a samsung 4K as well and one week ago when I switched on the tv the picture looked like a negative. For the first few days it took a minute or two and then returned to normal. However now it takes 15-20 minutes to return to normal. Can anyone help?

@alberius Go to Settings > Picture>Accessibility >Colour Inversion and switch it off. It will resolve the problem.

We can't hold the volume button down and go to contrast at the same time, I don't know what you mean?

I had the same thing with a samsung as well.

In that tv the problem was a bad ( polluted) t con flat cable. i cleaned the contacts with isopropyl. first remove the dust.

if this doesn't work : try to check the Pcb of the T con board. probably a bad IC. ( as15.. )(most of the time)

try to measure out first if thats possible.

if you are not sure, send us some pictures when you open the tv. we will show you what the t con board is.

Kind regards,

kevin

I had the same problem and I found something called picture inversion and shut that off and now it works fine.

Not sure of the model number but it's a 55 inch Samsung curved screen. Hope this helps.

Volume button just turns the volume up or down mute will just mute the set. It seems like when the set gets to operating temperature, and the set is then power cycled, when the set is turned back on it will go back to normal. This leads me to believe it's a loose or dirty connector that expands with heat.

Samsung universal remote

The newer Samsung TVs don't have volume or contrast buttons on the front panel. However, if you experience the inverse video issue, you can fix it using the TV remote's SETTINGS feature on the remote. Go down to General and turn off Inverse Video. Then exit SETTINGS to return to the normal color. settings

When I view recordings or menu page for Amazon prime, the images are displayed as negative, but this disappears when I start the viewing. Anyone help? My tv is LG 4K 49 inch.

HOW TO FIX: I don’t have a tv controller or settings on my Samsung tv, but I hit the back of my tv and disconnected the power cord or DCV, DC ,DV thing I don’t know but I disconnected that and connected it and then turned my tv back on and my screen was back to normal, hope that works for whoever had the same problem.
