Ive tried all the solutions I can find online, it made things worse.
Got a Samsung TV Series 5, 32 inch (Model LA32A550P1F). Its old, deffo 10+ years but the old dog has served us well. Covid19 income affected household so buying a new TV isn't an option.
About 18 months ago dark colours displayed as green, we dusted the HDMI port and it fixed the problem.
Then about 9 months ago the same thing happened, couldnt fix it but left the TV on for about 4 hours and it gradually came good.
Switched it on yesterday after no use for 4 days, green haze on all dark colours. It gradually got better and for 3 brief periods went normal before getting worse again.
No difference changing HDMI port or input source, same picture.
Picture view is on standard. We reset all picture settings, it made all the colours worse, green and pink haze over everything.
That lasted 10-15 mins then picture went almost completely black, sound OK.
The only way you can tell the TV is on by looking at the screen is a dark grey tinge around the perimeter of a black screen.
My next move is unscrewing the back of the TV. Ive read it can be a loose cable connection.
The only thing is we are totally clueless about stuff like this.
What do yoos reckon?
Im sitting here with a screwdriver in my hand waiting for approval.
