I ordered an entire 1600x900 factory replacement monitor (casing, webcam, LCD, etc) and took 'er apart and plugged it up, but there is nothing posting to the new monitor. note: the laptop WILL output both HDMI and rbg to an external monitor.

Anyways, as far as I can tell and multiple passovers, there is nothing damaged on the board. I've taken it apart and checked multiple times to the best of my ability, reseating the LCD connection to the motherboard and internally on the new display..

Now I know, it's possible that the new unit is faulty, but for some reason I want to believe it's more likely not than is.

So guys, what do? Is there any way I can test the power coming from the 40 pins on the mother and make sure it isn't goof'd somehow? Are there diagram showing the voltages coming from each pin and how would I go about testing that? Any help would be appreciated.

Edit : I have tested for backlight issue with a flashlight

I kind of bent the main board so this happened.

Question : I want to reflow gpu using heat gun and laser thermometer for measurement , what's the best melting temperature for it? I saw people go up to 260 but I usually solder joints melt at 200-210 Celsius , so I'm wondering if lower temperature will reduced the risk of burning the gpu completely…
