    820-00840 Won't POST

    Hello. Got this board from another store here. For what they said this machine got liquid damaged some months ago, their client brought the machine to them, they cleaned the board and it worked for some months. Now the machine came back not working. They sent it to me and the symptom is that...

    820-00138 Intermitently Working

    Hello. Got this board here. No signs of corrosion anywhere. No liquid damage. It works for some time, then dies. If I let it cool down for a couple of hours it works again for some time and dies again. No crash report is generated when it turns on again. Last week I tossed it into ultrassonic...

    820-2936 External Video Only Works Via VGA

    I tried 3 different working adapters. Also, costumer complained it wasn’t working with his own HDMI adapter before machine died. So it’s for sure not an adapter issue

    Hello. Got this board dead, no power. ISL6259 failure. Replaced it and R7051/52 as they were fried. Board works now. Internal video ok, external video only works with Mini DP to VGA adapter.

    820-3476 Orange Light No Power

    Hello. Got this board here that initially had no light on charger. It had been poked by another store already and had flux around PP3V42_G3H area. I managed to get green/orange light and 12.56V on PPBUS_G3H replacing SMC and U7090. Now I have a full short to GND on PPVRTC_G3H rail. Tried...

    820-2936 Strange Behavior on ASD

    Board had some corrosion. SMC has been reballed. Board was not turning on when it arrived. I think I’ll try to reball it again because today when I reflores it the machine worked for some hours and now it stopped again. Will try those resistors as well

    820-2936 Strange Behavior on ASD

    Now it’s worse! 4 sensors are reading wrong. TC0D, TC0P, TM0P and Ts0P. All of them telling SMC IO failure

    820-2936 Strange Behavior on ASD

    I will try flashing your file to test. Anyway, I flashed mine again and now it shows up sensors on ASD. Palmrest sensor is reading wrong. I tried replacing Trackpad and cable, but same results... Full speed fan and laggy trackpad. I think it may be some communication dateline that's wrong. I'm...

    820-2936 Strange Behavior on ASD

    Was what I thought... I will try flashing it again. Do you have any known good clean file for 2936?

    820-2936 Strange Behavior on ASD

    Because BIOS could not be read. I needed to change even the chip itself as it was fried... Machine was not starting with it. Edit... Ah, I understood now what you said... Will test without putting costumer's serial in it. Will post back, thanks!

    820-2936 Strange Behavior on ASD

    I could not copy FSYS from original bios, it was unreadable. Actually somehow original chip got fried. I flashed a supposedly clean BIOS from my database, which I already had used before and worked on other machines. Yes, I put client's serial on it.

    820-2936 Strange Behavior on ASD

    Hello! I got an 820-2936 board here that was not turning on. I fixed it and now it turns on, but sometimes fans go high and machine gets extremely slow. I then decided to run ASD to see if there are any sensor errors. But, neither ASD EFI or ASD OS show me the option to test sensors. It simply...

    No go... Now I don't have VCORE anymore... Will send this piece of trash to costumer again as a no repair.

    I don't have IR oven. Can I just put flux and try reflowing CPU?

    810-00045 Has All Voltages, No Video/POST

    Hello. Got this piece of shit here that costumer says data is crucial for him, but I'm suspecting as always on this model to be a bad CPU. Problem is the board powers on, draws around 300mA from charger out of the case, connected directly to genuine 96W power supply but has no POST/Image...

    Those would be L8360, L8310, L8930(already removed) and L8960(also removed). Any other coils? Will do it tomorrow as soon as I get at my store.
