its connector with 4 wires in square...

If i connect led tester to connector of led strips, it should automaticly adjust to how much power it needs and i can leave it longer time there will be no damage to leeds, becouse i want to test will it shut off after some time ?...

So i opened back of tv and on power suply there is marking like on image im uploading,,,LED 67v==========154V/650mA/max 71W
And when i test on 2 wires going to backlight with multimeter im geting 139.1V DC it works short time and then turns off backlight, video is still there and when i usse remote there is menu click sounds, im thinking its probably one led diode failed and there is some other with interiminent failure , it works and when heated it goes of, and power suply is compensating for one thats why its on 139V and when next diode fails it trigers protection from power suply......

Hi guys, i hope i get some help with my tv as i dont want to just throw it away
Basicly if its turned off for some time and cold, i can turn it on and it works 10-15 min, and then it turns off backlight, if i switch it off and on back it works again and goes off but each time in shorter period of time, there is image in background when it turns off so i gues its back light.

So now to the point, i cant find ANY info abaut wich backlight is in this tv, and no disasembly videos, i have done one tv before by my self and repaired it, it works till this day, so now would like to try...

Hi, im 37 years old and i like to learn new stuf abaut electronics daily, for hoby each weekend i repair something so it does not go to landfill...
