I have this board that came in due to no Touch Bar activity. Found knocked off L5110 which fix that issue. But now i noticed the keyboard backlight isn't working. The backlight is not even showing up as an option in the setting menu. Am i missing something here or does this board not support...

Same measurement. Though, D6950 did appear blown, has a hole through it. Went ahead and replaced it. Wondering if the smc was affected as well?

SMBUS_BATT_SCL - 0.484/3.3v SMBUS_BATT_SDA - 0.609/3.3v Only info give was it failed due to static electricity. From what i guard, they may have been trying to replace the ssd card when this occurred.

P_IN - 20.5v AUX_DET - 5.1v SMC_RST_IN - 0.0v VDDA - 5.1v VDDP - 5.1v EN_VR1 - 5.1v SMC_RST* - 3.4v AUX_OK - 3.4v AMON - 0.0v (battery not connected) BMON - 0.0v (battery not connected)

C7050 - 2.7v F7000(2) - 3,75v

Have this board that originally wasn't switch from 5v to 20v on PPDCIN_G3H. Troubleshot it down to U7000, replaced and PPDCIN_G3H now goes to 20v but no current draw. PPBUS_G3H is reading 3.76v. Any suggestions on where to go next?

Have this board that doesn't recognize the SSD. I've tried clean bios with same issue. PP3V3_SSD_NAND, PP1V8_SSD_FMC, PP12V_SSD_VPP all come on to their respective voltages, but after a few seconds, they all drop out. After about 5 seconds PP12V_SSD_VPP try to come back on, goes up to 10/11v...

So just as a last attempt at the board, not sure this was the actual fix, but i noticed U7710 had a short, so swapped it out. Was able to then do the DFU. The board appears to power up as caps lock comes on and off, there's usb activity and the laptop chimes when i plug in the power. I still...

Yep and no image external.

No usb activity. It lights up but doesn’t pulse Cap light also doesn’t come on.

PPVCCIO_S0_CPU - 0.96 PPVCC_CPU_PH1/2 - 0.85 PPVCCSA_S0_CPU - 1.02 PPVCCIO_S0_CPU - 0.95 PPVCCEDRAM_S0_CPU - 0.02

Yes. Both revive and then restore. It goes half way and just hangs for a long while before then switching to the locked symbol.

Have this board that won't power up at first. Found missing PP5V_G3S. Isolated to U8110. PP5V_G3S restored once U8110 is replaced. But board still isn't powering up. The fan does spin but that's it. Any suggestions? Here are a few voltage readings PPVCCGT_CPU_PH1/2 - 0.0v PPVCC_CPU_PH1/2 -...

Realized i never updated on progress. New OS fixed it. Thanks.

SMC_LID: 3.4v open and 0.0v once close. But the issue is present even when I don’t close the lid, when it goes to sleep.
