please check your private messages and these videos I recorded to videos of my desk with the board, one just booting and the other one while getting the voltage from VCORE.

with the USB pen drive there is no activity, and yes without ram VCORE stays high, so what next then.

yes, VCORE drops to 0.76, and there is USB activity I connected a USB ethernet adapter and I have link on the adapter and the switch as well, but like I said is weird cuz if I remove the ram I dont get the beep for no ram on it and I also have usb activity without ram. I did smc bypass and the...

everything is intact there.

of course, I lifted one side of each resistor. in this case what next? flash the original bios back?

nothing happened sr. Everything still the same. no video at all, I confirmed that there is mouse activity, noticed that the DVD ROM is not powering on, before flashing it was. I also tried an external monitor just in case. I'm curious about something, why there is no beep when there is no RAM...

Hello, thank you for your valuable help, unfortunately, I don't have medusa yet. if is not too much to ask you, how can you do that with the .bin file? is there a guide for that? I'd like to learn ho to do it. https://drive.google.com/file/d/1zwrXl1b5tBnedsh_qexrI70pB6f5DP_x/view?usp=sharing BR

that sounds in part good. Sorry for my ignorance but how can I disable the GPU in BIOS?

VCORE drops to 0.75 without the battery connected and just the display and ram on it, but with the battery connected, the display, and ram it drops to 1.06. is that normal?

I bought that T862 when I didn't know anything about repairs, then I realized that it was wasted money. which bga machine do you recommend, maybe it worth it try to spend some money on that.

too bad, I guess that I need a BGA machine for that. I do have one but I'm not sure I'll be able to do that job with that. I bought that very long time ago. please see the link and let me know what do you think about that cheap BGA rework station, and please also tell me where I can get the PCH...

I turned off the OVP and let the amp to the max, the only thing the gest hot is the PCH, I used a seek thermal camera for that

Hello, this MP turns on, charge, have green and orange light at MagSafe, but there is no video and no chime either, there is no sign of water or burned parts, flashed the spi just in case and nothing, removed the ram and no beep, connected external monitor and nothing. any clue where to start? BR

it looks like it is a dead PCH since the only thing that gets hot is the PCH, also noticed that PP3V3_SUS is shorted to GND too.

yes, with no LCD connected. tried that but my dcps have and over-voltage protection functionality and because of the short is not allowing me to inject the 3.3 voltage. I selected 100 mA and nothing. do you think that if I turn off the OVP (over-voltage protection) nothing would happen?

thanks for replying. 4.8 ohm

Hello guys, I got this MP with the following problems. It turns on, the fan spins normally first then starts spinning faster, it charge, there is mouse activity, but there is no video, no chime and I noticed that the PCH gets hot when it is on, also I found a short to GND on PP3v3_s0, and since...

Hello, I'm new to this forum and in the mac hardware repair business as well. I've been fixing phones and solving PCs software problems for many years, so it is possible that someone here could help me out with the repair rates? I just don't want to be too cheap or too expensive just because it...

Hello, do you still have those untouched MLB? Depending your prices I might be interested.
