[Fizzl92]

Hello,
i have an Macbook Air 820-2375-A witch has no image. It also dose not chime. I dont know if the volume is turned off or it it is not starting properly. But im sure it has no image (not only no backlight). It also shows no signal with thunderbold on an external screen.
Thanks for the help!
Felix

Dead MCP79U. Do NOT fix this, these machines are hopeless.

OK thank you very much for the fast reply. I guess you know from experience . So no measurements needed. Normally if the fan spins its fixed. This time the fan spins and its dead. Something new to learn for me here
