What could be the problem?

Hello Guys, so i changed backlight bcuz it was blue recently. I bought new ones from aliexpress.After 7days i have been using it a few hours a day maybe. Today i turned it on and it was blue again, i turned it on and off again it was the same blue so i turned it off again. Then i let it rest for like 5 or 10 min and i turned it on to check it again and it was working normally. What could be the issue?

My tv model is UE43TU7102KXXH. It only has one board in it.

@patriknemeth first it will depend on how blue, blue is. Next turn your backlight brightness, down let's see if this makes normal lasts longer. I am not to fond of the quality of some of the strips on Aliexpress. There are a lot of "less than good" products. It's always a bit of a hit and miss.

It could be bad backlight strips but there is always the possibility that this is related to the video processor on your main board, or the Gamma IC (less likely).

@patriknemeth anything is possible. My prime suspect are always the backlight strips but let's see if they are now functioning. If so, who knows what was going on with those but just enjoy your TV. .
