There are ways to test the strips and there are spares on the web (shopjimmy.com) but you are a TV tech so you know what to check now. This is not a TV repair forum so I pause here.
Blinking Samsung TV (UA32EH4003). 3 years old and no warrenty. This is how it looks after turning on the TV. Pls watch video. Any suggestions? Power board?
I have this problem on an smart tv uhd samsung(connected with 1080p devices), just blinks when i turn on, after a few minutes stops. The samsung support came to see it and change it her main board, the blinks continues. I still didnt discovery what is the problem with the blinking, what i can say, she only blinks when the hdmi cable is connected, when take out the hdmi cable, and open any app she doesnt blinks. Maybe some problems with the tv's hdmi (using hdmi 2.0 on tv in hdmi 1.4 devices).
