    A2338 5v 0.05-0.020

    This computer has come to me three times in 8 months..

    first visit came with a backlight issue; turned out to be missing turned out to be missing line from LVDS, repaired by jumper wire

    second visit came with a power issue, turned out to be bad mPMU, replaced it and it turned out..

    now third visit, came with 5v cycling up to 0.18 amps. one port cycles and one port does not cycle.. on thermal camera I noticed UF015 was pulsing also SEP EEPROM.. I measured around UF015 and found PP3V8_AON_ATC_ISNS a bit low but it has voltage..

    I went to replace both CD3217 suspecting that one is cycling meaning one is bad.. still same issue..

    Kinda tired of this device.. what's next

      Tried replacing the eprom just for the sake of it and see if the readings change; same readings..

          Samsung UN55F7050AFXZA ver. TD01 power cycling
          by high-tech
          Hello everybody, I could use some help on this one... It's got me guessing...
          I took pictures of all the boards and the pin out of the connector on the power supply that goes to the main board... I measured all the pins in relation to chassis ground, here are the result.

          (B13v)1. 12.7 volts cycling (Vamp) 2. 12.7 volts cycling
          (B13v)3. 12.7 volts cycling (PWM5) 4. 1.0 volts cycling
          (OD_LE)5. 2.8 volts cycling (PWM4) 6. 0.9 volts cycling
          (OD_ON)7. 2.8 volts cycling (PWM3) 8. 0.9 volts cycling
          9. ground (PWM2) 10. 0.9 volts cycling...

          Macbook A2338 / A2337 - Replace SSD
          by todordm
          There are a lot of Video Tutorials how the SSD of A2338 or A2337 can be upgraded. Normally they say you can order the bigger SSD chips (0 and 1) from China. But as far as I understand you can take the SSD chips of one A2337/A2338 and install on another, put to DFU mode, do the recovery, reinstall etc... I tried that several times (tried to upgrade 256GB to 512Gb, then to 1TB, then to another 256Gb)... nothing worked. So my question to the community is: can I just take the SSD chips from one A2338 and intall them on another A2338 (taking care of course of the 0 and 1 positions)? Or I have always...

          by User555111
          Currently Im trying to get this A2338 13" 2022 MacBook Pro M2 to function properly, Right now the trackpad and keyboard are not working but the power button and keyboard backlight are working. the Touch Bar shows display but does not respond to touch. I bought it on eBay and it was described as having a bad lcd. When I received it however I found that it was also missing the wifi and bluetooth antenna along with most of the screws hardware. it was also showing picture on the LCD but no backlight, I could also see some lines on the screen indicating the lcd was also somewhat damaged. on top...

          MacBook A2141 one USB port dead and one power cycling
          by dbuergi
          Hi all,

          I got a 16inch MacBook Pro showing 5v and 0,3a on the left ports and right side has one power cycling and one showing nothing. The one cycling shows 30c under thermal camera. Surrounding components show no corrosion or any shorts.
          Any ideas what to check next? The whole board looks clean compared to the other A2141s i saw....

          A2141 820-01700 Power cycling (DFU worked ok)
          by mon2
          Hi. Working on an A2141 that is power cycling. Powers up fine (20V @ 3.1A peak) -> fan spins ok and then at a higher speed (after we removed the trackpad so the sensors are missing) -> chimes ok but after the high fan spin -> power cycles and repeats this loop. We did manage to DFU the unit with revive mode (4/4 steps completed ok) -> resulted in a brief padlock graphic before power cycling. Unable to toggle the keycaps led since the boot does not reach this far of the cycle.

          Q: Does the DFU process validate that the nand flash is OK ? We do not wish to restore this board...
