Hi, I need help with this Mac. The trackpad is clicking. The only components showing signs of heat are the T2 chip and the battery coil. There's no short on the coils, and diode mode is normal. PPBUS_G3H - 12.6V SLP2 and AWAKE voltages are present. NAND power rails are at 0.9V, 1.8V, and 2.5v...

The Mac is liquid damaged. Keyboard and probably screen. No power. On the LB there was liquid on the U5700, UT00, UF750, around the UR630. There was some liquid coming out from under the shield opposite the CPU. The customer took it to me 30 minutes after the liquid accident. On the amp meter it...

Hi. Got this Mac to repair which has no signs of liquid. No previous history. Battery is dead, but I tested with a good working battery and still same. PPBUS_G3 - 12.7V PP3V3_G3H_RTC - 3.38V PP1V8_SLPS2R - 1.8V Cycling. T2 is glowing from one side and cycling. SLPS2 and Awake is all cycling...

This LB has no signs of life. Stuck on 5V 0.294a on all ports. No liquid, very clean inside. Tried DFU and it gets stuck half way on installing system. SLPS2R and AWAKE voltages are present. No short on the board and all coils measurements is good. S5 voltages are missing. PPBUS_G3H - 12.28V On...

Sure! Here's your corrected text with improved grammar and clarity: Hi, I have an issue with this MacBook Pro 15" (Late 2013). It has kernel panics and everything points to a GPU issue. Using GMUX software, I can disable the GPU, and it works fine. I’m not sure how long it will last, but it...

Hi. I need help with this LB. Mac CPU gets mad hot while on battery, trackpad clicking. LB stand alone gets 20V and current draw varies between 0.05 ~ 0.1 amps and stabilize at 0.04amps. CPU gets hot just when battery is plugged in. Standalone it does not turn on. All the coils measurements are...

Hi, I need some help here, please. I have an iPad 11 (1st Gen) that came in for repair due to a “no power” problem. Upon inspection, I discovered corrosion and burned pins on the charging port. Many of the pins were damaged and shorted together. I replaced the CD3215 and 610A3B components. Now...

Hi. This Mac came in for no power after is stays not touched for a year. The main issue was the battery, so after replace it and charge to 100% I left it discharging to test how long it would hold charge. But after 1 hour I came back to it and there was no backlight. For some reason the...

Hi, everyone. I need some help, please. This Macbook came in with no power. After inspection I found Liquid damage, corrosion near USB C controller (CF300) Both ports were initially stuck on 5V Replaced the USB C controller that is stuck on 5V, no difference. Replaced the second USB-C...

Hi, Good morning. Please, I need some help with this repair. It turns on only on battery, but it won't turn on when it runs out of battery. C520D blown/melted (PPDCIN_AON_CHGR_R). Removed. Diode mode readings to ISL appear correct compared with a working board. PPDCIN_AON = 5V...

I know this is a niche and its unlikely there is any answer, but a shot in the dark is worth it I replaced the LCD on a 2021 16" and customer complained about no FaceTime camera being detected and backlight issues - I replaced both ICs and backlight works fine now. I have tested the customers...

Hi, I have this A2337 with liquid damage to the audio board and to the keyboard connector (PPBUS_AON_IPD_FLT - 3 pins completely gone on the FPC connector). I removed UC850 and replaced but still had abnormal reading on this line, so the IC wasn't the issue. PP1V8_AWAKE had a short due to...

Hi, everybody. I need some, please. This Mac had liquid damaged on the Audio board and its cable. I've replaced both of than and Mac started to turn on. But it sometimes will have a backlight for a second when turned on and then goes off. PPVOUT_S0_LCDBKLT_F - 43.45V Even when the backlight is...

I need help with this M1 Air, please. According to the customer, it was liquid damaged a year ago and has been off since. The main corrosion was on the U5200 and around. I've replaced R5230, U5200, U5215 and U5216. Was stuck on 5v 0.04A and after replacing all components it changed to 5V 0.190A...

Hi, good morning. According to the customer, the Mac restarted after a few hours of working on it and then stopped booting into the system. All awake and main power lines are present in the NAND modules and are not clinging. I have tried the revive option, which goes through all the steps...

I need some help, please. The Mac has no signs of life. There is no liquid and no short anywhere on the board. All the coils measurements in diode mode are matching with the measurements on the FlexBV. I've tried to connect to another Mac, but it won't recognise it. Both USB-C ports are getting...

Hi, everyone. I'm working on this board with liquid damage near U1900, R5614, C1210 and U5800. I've replaced a few resistors and caps in those areas; some weren't turning on before. So, after all the work I've done and doing a U.S cleaning. The board now comes on and the fan is spinning at...

Hi everyone, I need some quick advice, please. The MacBook came in with no power. Trackpad clicking and cycling. It has been opened before, presumably by the customer. The screen shield is missing for both the backlight and LVDS connector. There are no obvious shorts under the thermal camera...
