Hello, i have another tread active and you guys are great.
I got this Samsung UN46d6003SF that has picture and everything works but image is kinda dark. I actually opened screen up and looked at led strips and they all light up. Edge lit screen from top, two strings of leds along top of screen only. No dead leds. I can stare at them and they are not bright bright. On power supply it says that power to led string TOP1+ should be 255VDC but i am measuring only 230V. I have measurements at led strip connectors as shown bellow:
BACKLIGHT ARE AT 20, multi-meter negative probe on tv chassis
TOP1+ 230VDC
TOP1- 111VDC
TOP2+ 111VDC
TOP2- 9VDC
Tv does respond to backlight level change and it gets darker to where at Backlight 1 TOP2- is about 134VDC.
Compared to working 46 samsung this one at full backlight level looks like good working one at level 4 i would say.
Picture of power supply is attached, provided by shopjimmy.
