Motherboard P8Z68-V LX NO VIDEO
The video card and ASM 1440 chip burned out. I replaced the chip and installed a new video card. The computer starts and all the fans spin, but there is no picture. Can you advise what could be wrong? -

MacBook Air A2681 M2 no backlight 820-02536

If there is no crack on the LCD from different angles but the backlight works, look for debris that may have gotten under the cable. Based on the user's indication that the image faded gradually and with artifacts, this points to a broken cable.

This thread describes the lack of voltage in the GPU, not the integrated GPU, as in my case.
