board came in with high fan spin no brain. once i got to work on it the board started working again it chimed and booted so since it had prior water damage i placed it into the ultrasonic to get rid of any lingering corrosion. upon putting it back together it wouldnt power on. after inspecting i...

as stated no voltage for cpu. board had very unnoticeable water damage as if its been cleaned. one of the ton resistors (r7403) was giving a wrong resistance changed it even changed u7400, Q7510, Q7520, Q7550. Checked traces from ton resistors to u7400 and nothing was wrong there. yet no...

got this random board had a couple knocked off components replaced n retraced i get no green light and ppbus_g3h is around 1v, 3v42_g3h is present. replaced isl but nothing changed. no green light on charger. i dont have much hope for this thing i can tell someone may have tried reflowing it...

so 3v3_s5 seems to be shorted to ground i get a beep on my meter but when i inject voltage my power supply doesnt helkp me find it. must be too small of a short to be detected? what other tricks can i use?

The macbook turns on cpu heats up and fan spins but no chime no image nothing on external monitor. I use a backlit keyboard to test machines to see if theyre at least booting on these ocassions but it doesnt even light up. My guess is that its brain dead but cpu is present at 1.8v so not sure...

Macbook had water damage retraced some areas reflowed smc and got it working but had no backlight. After working in backlight for a bit i realized the machine stopped posting. ppvcore cpu is 1.1v not sure what happened but last thing i did was replace the led driver thats when it stopped...

already tried a known good speaker and i get no sound from it. no chime. j6703 does get voltages under 1v each pin gets. but on a known good board those pins get no voltage at all tried swapping out u6620 and u6610 no luck. machine produces sound from the small speaker but not sub

checked all spi termination reistors and traces all is good even reprogrammed bios with no luck. board had prior water damage it did at one point keep fan spinning but got no cpu checked the cpu ton resistors for u7400 even replaced u7400 still no luck and board is back to quarter fan spinning...

I get a chime and a backlight but no image tested with a known good screen and no luck i just get a black screen. voltages on pins 2,3,4 of j9000 are 3.2v

no pm_slp_s5_l no pm_slp_s4_l S5 rails present at proper voltages Smc has been changed with a known good still nothing battery charges i get a green light on charger using original charger PM_BATLOW_L = 3.3v PPVRTC_G3H = 3.3v PM_PCH_PWROK = 0v PCH_DSWVRMEN = 3.2v PM_DSW_PWRGD = 3.4v...

turns on boots into OS but no image on screen. j8300 pin 1= 0v pin 2= 0v pin 3= 4.5v pin 4= 1.5v pin 5= 1.4v pin 6=1.8v pin 7= 2.5v pin 8= 2.5v pin 9= 1.8v pin 10= 2.8v pin 11= 0v pin 12= 1.5v pin 28= 5v pin 29= 5v pin 30= 5v I can see the screen turn on but its in a blank state with no...

customer stated they left it charging overnight with an external HDD plugged in and it just stopped working. did extensive troubleshooting and found out theres what seems to be a short on pp3v42_g3h (multimeter beeps when checking) now in these cases id do the usual inject voltage to find what...

this laptop came with water damage got it to power on and everything works fine but the fan spin rises and stays loud. i tried 3 different smcs. 1 smc was from the model with less ram but of course it didnt work correctly although the fan speed stayed normal. then i tried 2 smcs of the same...

Will LFXP2-8E5MGCAD2 work on a 820-2610?

So this machine runs fine battery is detected and charging. issue is it wont turn on unless power adapter is plugged in. I cannot pinpoint the issue any ideas? This board had prior water damage and was cleaned by someone else. seems like the power button is unresponsive until adapter is...

So this is a macbook i fixed about a year ago initial issue was 2 damaged caps from possible water damage. so customer tells me it wont turn on. I go look at it and I see the hard drive light is on but no life on the macbook as if its just restarting losing power and repeating. i take it open...

history is severe water damage i completely cut off the thunderbolt circuit and replaced everything that looked severely damaged also restored some power rails. reflowed smc which brought back charging orange light while battery connected. I do get a green light. so im down to the 3v3/5v_sus not...

anyone know where i can purchase a stencil for this gmux chip?

board delays to turn on, once fan spins it will spin for about 5 seconds then stop and spin a second time and stay on. no image on display, no chime, no image when connected to external, cpu gets hot and when connecting a usb mouse it has power i thought it was bios but nothing changed after...
