after inspecting the mainboard i see no liquid damage. i did find the lid angle sensor corroded but still no backlight after detaching it but the keyboard started working again 12v on ppvout_luxe_xw. i can see an image on the screen though
this board had a spill on one side of it and after cleaning it thorougly the 3v8_aon rail was missing.. u8100 got warm with voltage injection so i removed it. now 3v8_aon is 1.4v. Is that because u8100 is needed for that 3v8_aon to be 3.8v?
i have a 2020 intel mac air board that had liquid damage and after a thorough cleaning the only issue i found was that pp1v1_s3 has a 5 ohm resistance to ground and the charger was stuck at 5v. i used a dump that found on the internet to program u3060 but now the charger stays at 20v even in...
It has no visible liquid damage. When using a 60 watt charger, the ppbus is 12.6v but it does not boot with the charger alone. When booting off the battery, it will power cycle. The cpu vcore it disappear every 8 seconds but when i plug the charger in then the cycling will stop. Is this an smc...
had an a2251 830-01949 with a cracked screen and replaced it with a new screen purchased from amazon. the new screen is being sold as compatible with multiple models. It never showed an image but i did the mouse test and the optical mouse registered and sometimes the caplock key worked but no...
could you help me out with this board? it had a burned phase mosfet on the cpu circuit and when it powers up the fan never spins and the cpu never gets warm. dabkxdmb8e0 is the board model
this board is look similiar to the a2485 logic board. It had a spill in the audio amp area (ur600, ur630 and ur660). the rest of it looks unbothered. f5200 and f5201 are reading 3v. pp3v8_aon is 0v. this is very unusual since 20v is showing the usbc port meter
3v8_aon_spmu was shorted to ground after a liquid spill and the rail was restored after removing a burned capacitor. The board booted up fine and everything worked until the next day when the display had no backlight. I probed around UP800 and must've shorted something else because now ppdcin...
the board does just like the older mac board used to do. The fan slowly ramps to full speed and it's laggy. Is there an smc bypass procedure for the newer models?
this board has me vexed. i've reprogrammed u3060 and changed both u3200 and u3100. i've also used several usb-c jacks. it basically gets to 5v 0.215a and then it loops. I can get it boot all the way with a charged battery. can't get it into dfu at all
i don't work on many non apple board so i'm a bit confused by this asus board. There was very low resistance on three power rails. +1.8VSUS and +1.05VSUS and +3VA_DSW. I removed the pch and the shorts were gone. i'm assuming they were shorts because they measured 0 ohms to ground. I replaced...
It had a dead short to ground at c7804 which is pp3v3_g3h_pmu_vddmain. I injected 3 volts to find it. now pp1v8_slps2r is 0v. do i need to replace to capacitor or no?
this board had a liquid spill and now it will not start with the charger alone although the magsafe charger has an amber indicator . it only starts with the battery but it appears to charge
i tried a revive it with the configurator and it gets stuck at step 4 of 4 installing system. force quitting the configurator is the only option. the board remains in dfu mode afterwards.
i have a playstation 5 with faulty gddr6 memory.. the resistance on the power rail is very low but when i inject 1.5 volts it doesn't draw more amperage than a good working board. is there a way to single out the faulty chip without removing all of them? it has 8 of them. Could I damage it if i...
