    820-3437 smc_lid = 0.5v

    No Title Ok, so I put a new SMC (brand new), and still have all the same. There was only a little bit of spooge on C5021 & R5115-1 (no stuff). Fan spins, CPU gets hot, and ALL_SYS_PWRGD = 3.3V. I did try doing a PRAM reset with a new keyboard and cable (I don't have a usb keyboard). There was...

    820-4924 Turns on No Chime No Display

    No, not yet. Duke suggested the SMC because there was a drop of water there. Once I catch up on my work I am going to give it shot. Will follow up.

    A1398 Shows logo, nothing happens

    OK, give me the dumb-ass award. ASD doesn't run without wifi card installed. All answers answered. Close this out. How do we delete Louis? There needs to be a delete button, or else this looks like my fucking diary.

    Nevermind. I think it was getting too hot. I put on some Arctic Silver and the cooling fins and boots normally. However it still will not run ASD. Why not?

    Will run in SMC bypass, but won't do ASD. So SMC issue then I assume?

    A1398 Shows logo, nothing happens

    I tried all the resets, won't do safe mode. Will only show the logo and then nothing. Was water damage around the LVDS on backlight pins only, really light. No backlight, but with new LCD assembly is backlight. Don't see any other liquid anywhere. Ultrasoniced anyways. I've checked the drive is...

    [SOLVED]A1398 820-3662 No image after screen repair

    So I am trying to order some more of these from Digikey. But I can't figure out the values of what is needed. The schematics say its an inductor L, ferr makes me believe its a ferrite bead? But the 220-OHM is confusing.

    [SOLVED]A1398 820-3662 No image after screen repair

    OK. I changed L8300. Out of the several screens that I was testing with, the one that had a distorted image is actually good when I used the good L8300. You can close this mystery out ! A bad L8300 can cause a distorted image. I thought L8300 was good because it had continuity. L8300 is an...
