I am looking for the boardview that shows both the top and bottom of the board. I was able to find 1 boardview but it only shows the top of the board and not the bottom and that file has to be open in allegro. The model of my board is NB8511_PCB_Mb_V5

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
