Hello, This is my first post here and i must say...this is a great forum!
Anyways, I've been getting into repairing Tv's lately. I know my way around electronics pretty well but I am not really sure how to accurately test an LED backlight inverter. Normally, i will check the pins through trial and error and if it comes up with a reasonable voltage, then i would consider it to be ok. I know many of the backlights will be in the 24v-50v range, depending on the number of LED's and how they are wired. I come across boards like the one shown below and am not understanding the terminology. The 9-pin plug is for the Backlight cable. Can anyone shine some light on what these markings stand for and what is the correct way to check it? I will add that not all pins are used on this particular backlight cable.
Thanks!
