I am working on a clients iMac that will not boot. They state the computer rebooted on its own and then got stuck at the loading progress bar. They do not believe it was some type of firmware upgrade progress bar. After rebooting there is nothing on the display, no chime, and no caps lock. Pram...

No liquid. Board looks good. 19v .160a The fan does spin and slowly ramps up. As the fan ramps up it goes to 0.230-0.240a and stays there. No caps lock light

Logicboard Keyboard Connector.... No pins from the connector are shorted with the ones next to them. I check both sides of the connector for continuity. PIN 2 of the connector FAN_LT_PWM has continuity to Q4800 pin 3 PIN 3 of the connector FAN_LT_TACH has continuity to R4800 and R4805 I have...

That's one connector that I do not want to remove unless I absolutely have to. Although the connector looks fine, there must be a damaged pad underneath, like you said. What would my options be to run a wire? Pins 2 and 3 of the connector are FAN_LT_PWM and FAN_LT_TACH.

Moving the board to another case reproduces the same issue. SMC issue?

Resistance R4800 - 36 R4805 - 46 R4810 - 100 On my donor board, I am getting.... R4800 - 46 R4805 - 46 R4810 - 100 Would the R4800 difference matter?

I have swapped the fan with another but the same results. I guess I could order a new fan but I don't believe that will make a difference.

Replaced Q7040. The fan does not spin loudly every time. Only the first time on a fresh boot. It stays on while charging now. The fan does not seem to run at all now. If I run apple diagnostic it does the loud fan spin and comes back there may be an issue with the fan Error PPF003.

Also... I tried a replacement keyboard/palm assembly and a new CPU fan. It does the same thing. I also located a donor board in my stack.

"Small" water spill on the keyboard. Keyboard flex was destroyed. There was a small spot (picture attached) around C7051 and Q7040. Cleaned around the two components. Replaced the flex cable and the machine boots, charges, and does boot into the OS. Keyboard and touchpad work. When you first...

820-00164 GREEN LIGHT NO FAN - I removed the board from the case and noticed water stains under the fan. When plugged in I could feel heat coming from the area to the right of the fan. C7323. Confirmed the short with a little alcohol. After removing C7323 I get fan spin. I do not have another...

I replaced my USB tester. It is only getting 19.6v and not 20v.

Tried the PRAM and SMC reset. The USB tester does not change at all when I reset the PRAM. Stays at 20v 1.43a now after power cycle. That could also be my usb tester not being 100% accurate. I plugged in a usbc to hdmi adapter and nothing is on the screen. No touchbar either. How can I test or...
