I bought a dead device on local ebay. Water indicators are all red, it was really sodomized by someone around Q7010 (PPDCIN_G3H_ISOL), D7010 was soldered reverse, C7590 and C7572 were also cracked of the board. The board autostarts only with battery attached, goes to 0.25A(old battery is...

what about 10 minutes? I mean, i did 30 min on some PC Notebook boards (believe me, German beer is almost impossible to remove with alcohol/glass cleaner/acetone/Amtech flux). Is there something special about macbook boards? as for keyboard, i had 2 successful cleaning with alcohol bath, it was...

what about ifixit kits? are they any good? honestly, because the lack of supplies i did 2 iMacs with 3M tape, i use the one which is popular in mobile repair service, to get proper thickness i use two layers. i guess i gonna give both customers a call.

no well, all the fluctuation you see is a sign of boot loop, your main problem. the common techniques are to try good-known BIOS, check for the shorts on all peripheral chips (like audio IC), try to start it in SMC bypass mode, and so on. If you see that board starts till the FAN spin, it is...

well, repairing PC Laptop isn't bad at all. here in Germany people invest 200€ for a board repair even if it's a 400€ device. . It is not really difficult too: if you have an IO chip failure you just order a new one and program the damn EC bios chip which almost always comes in a good neat soic8...

i"m pretty sure there's a backlight parameter in NVRAM so i guess it is possible to make it always-on. But i guess you're right, KB LED PWM looks quite different and seems incompatible with Backlight control.

well, what if we could use Keyboard LED PWM to control the Display Brightness? unfortunately, do not have any device to experiment on, but if we could route and adjust this signal to LVDS Led driver, it could be a sollution. Of course, 12 -jumper mod probably takes to much time to make sense. (i...

Hello everyone. This is not an advertisement of any kind. I guess i'm not the only one who looked at the schematics feeling dumb and confused. I always thought, "shit where are people learning this stuff??" so here we go https://www.youtube.com/channel/UCJQkHVpk3A8bgDmPlJlOJOA example of how...

You should figure it out by yourself. Get a donor board and do some experiments. first of all, temperature changes exponentially, 1cm and 3 cm is a huge difference for a hot air gun, so if you see "temp" control knob on your hot air station, you can call it a "REPAIR SPEED" and use a Louisses...

So charger chip is U7100, page 50 in schematics. So here's some ids for charging shit: R7150, R7151 R7152, as well as R7120, R7121, R7122, also caps for shorts: C7120, C7121 also, Q7155 for voltage drop, PPVBAT_G3H_CONN resistance to ground also shit on lines CHGR_ICOMP, CHGR_VCOMP, CHGR_VNEG...

I might sound stupid but is it a proven good battery? check all the current sense shit on the battery charger, feedback and boost around power and charging mosfets. Read charger chip datasheet and check if your voltages are meeting charging conditions. (Be extremely careful with probes, it is...

well, so actually chips are unavailable like I said. GMUX bypass is somehow better since you don't need to fiddle with OSX kexts to disable the GPU like you do if you cut the GPUVCore. it also works if you get a fried board with bubbles under the GPU chip like the guy on this video.

no water damage, no physical. if i understand you right, there's no shorts on data lines on camera/LCD.

there's no image at all, it simply fills led matrix so it becomes opaque just from the start. i guess it happens when LCD receives its PP5VR power. eDp is not detected at all, laptop boots to osX and Linux, it detects normal display port and HDMI if connected. I will try to check if Intel GFX...

Black screen, no backlight, no image, TFT matrix switches to all black during boot (light stops coming through the logo when Laptop is on). Works perfectly with external display, does not detect eDP screen and Camera. PP5VR3V3 = 5v. I would instantly buy a new Display assembly if only ASD did...

Can you please drop a proved link where i could buy some? btw, check this out, A1278 UMA downgrade. It is Russian but video is self-explanatory: https://www.youtube.com/watch?v=wi1qst2KY6A

Just wanted to know what do you guys think about it. Since no one can really replace this chips with the newer one, i am providing my customers something like a "you asked for that shit repair": 1. Reflow 2. Liquid metal + MacFanSpeed to always keep GPU under 60°C 3. 1Y free software+hardware...

Do you think it makes sense to heat the cable before bending? I guess PVC can handle 100-120°C, but would it be enough to make it more ductile?

you have 2 knobs, C.V and CC. CV stands for constant voltage, CC is Constant Current.

looks more like system KP reboot,1 min is a long post even for apple. you need to reset SMC/PRAM to be sure it's not chiming.
