Macbook A1932 Sensor Issue

[Instafixx]

Macbook A1932.
Machine switches on Normally. Screen goes blank at Apple Logo and Half Status Bar.
Tried different trackpad cable and different trackpad. Didn't work.

Did a DFU Restore. Now Machine boots up fully and then the screen goes off sometimes at the password screen. Sometimes after login.

Close the Lid and Open it. It will some-time turn on sometime not.

Check the screen behavior disconnecting audio flex.

Tried Disconnecting Audio flex and both speakers too.

Still the same.

Check SMC_LID_LEFT/RIGHT behavior when open/close the lid.

I tried checking with another LCD assembly. It works fine. Can it be a LCD issue ?

Test it more time, assuring correct sleep/wake events.

But is it ever a lcd issue ?

It's basically an EEPROM issue. Where can I find a clean eprom file for it ?
