Lcd no back light
So a customer of mine let his friend work on their computer. The screen was originally damaged so they bought a new LCD that came assembled with the frame. The back light was not functioning. The customer came to my store with yet another brand new LCD assembly also doing the same thing with no back light. If I connect the computer to a TV using the HDMI port it works fine. I found that one of the chip next to the LCD connector looks damaged. However, if I use my multi-meter it will beep only if I touch the pins on the chip and not where its soldered to the motherboard. My question is if I apply a bit of solder to the chip would it be okay or should I just replace the chip. "P" chip tested fine, but looks a bit messed up. I provided some photos below. Any feedback is appreciated.
