early 2015 MacBook Air LCD is there an inverter board?

Dear IFixit reader,

I have an A1466, Early 2015 MacBook Air, whose LCD assembly was replaced and it still exhibits the same symptoms before replacement.

This begs the question, is there a separate inverter board attached to the motherboard, or does one have to replace the whole motherboard to fix the problem? I attempted zapping the PRAM, resetting the SMC, attaching to an external display (which worked), single user mode, open firmware, but all result in the same problem, very dim unreadable display.

Disconnected the battery each time, held the power button down 30 seconds, and still no change.

Thank you.

Sincerely,

A tech repair person

First if this was still faulty after the repair you really need to go back to the shop and get it resolved.

Sorry to say the LCD backlight is LED so there's no inverter like a CCFL would have.

Instead a Buck controller is used to manage the power to the backlight LED's. Check out the MacBook Air 13" Early 2015 Teardown Step7 (Texas Instruments TPS51980A synchronous buck controller). As its near the edge of the logic board it can get damaged from a liquid spill.
