No luck. Audio flex was not connected and I used PMU_ONOFF_L as power button to make sure board is turned off.

No, 0V

Cant find any corrosion. There was 5V on both ports and both CD3217 chips was getting hot under thermal camera. Both replaced and now got 20V and 0.05A-0.1A from charger. Only T2 chip gets little worm. PPBUS_G3H 12.28V PP5V_G3S 0.018V PP5V_S5_LDO 0.012V PP3V3_G3H_RTC 3.28V PP3V3_G3H 3.22V...

With battery 20V 0A from charger (MagSafe 3got no light, tested on MagSafe and USB C) PPBUS_AON = 11.05V Board only: 5V and 0.24A from charger, after few seconds drop to 0.06A. PPBUS_AON = 11.99V Diode mode on PPBUS_AON is correct. PP3V8_AON = 3.79V Removed F5200 and F5200 and F5201/1 got...

I got fully working A2337 and swaped board and the same issue so for sure something wrong on the board. Compared JE900 in diode modes and only on one line got strange reading: JE900/3-6 PP3V3_AON_VDDMAIM .320 (good board .178) "Also check around U600." Cant find U600 but I think you mean...

JE900/11 .383 JE900/13 .320 (boardview says 0?)

Audio board was affect by liquid. There was webcam connector on display board badly damaged and LP670 melted (client don't care about webcam). Replaced audio board, it boots but there is no audio from internal speakers. When pressing vol UP/DOWN I see on the screen volume change. Audio input...

Cant find any liquid damage. One port charge only on one side, nothing on another side. 'Mac USBC & EDP meter" shows correct diode mode readings of JB500. Replaced CD3510 just in cases and no progress. Diode mode values RB630, QB630 are correct. When plugged on the faulty side got 0V on FB200...

Tried DFU revive and restore with the same error. libusbrestore error:21 [com.apple.MobileDevice.MobileRestore - 0x15 (21)]

After liquid damage. Connector on Display board was burn out. Testing with know good display assembly and flex cable. PPVOUT_LCDBKLT = 51V PP3V3_SW_LCD_CONN = 3.27V PP3V3_SW_LCD = 3.28V EDP_PANEL_1V8_EN = 1.78V PP5V_SW_LCD_CONN = 5.1V PP5V_CAM = 5.1V Any idea?

Forced method works. Did 'Revive" during 'Installing System' around in 1/3 process with error: "Gave up waiting for device to transition from DFU state to DFU state. [com.apple.MobileDevice.MobileRestore - 0xFCA (4042)] Tested with know good battery with 60% of charge. Data is the most...

"Check resistance (ohm scale) between PPBUS_G3H and L7702." 3.97 kilo ohm "Remove R6900 and check again diode mode to ground at PPBUS_G3H." When was checking R6900 I found crack on U6903. After U6903 has been replaced I got high value in diode mode on PPBUS_G3H. With soldered F7000 I got 12.26...

OK, today there is 5V and 0.35A from charger. Removed F7000 and on F7000/1 got still 12.55V and F7000/1 got .022 in diode mode. During comparing coils in diode mode found short to ground on L7660. Injected low voltage to PP3V3_G3H and U7800 was getting warm. Removed U7800 and short on...

Will check rest of coils soon. With battery connected got 20V and 0A from charger with short spike to 0.025A. Got 9.60V on PPVBAT_G3H_CONN so will test with charged battery soon.
