Just finished writing a feature in FlexBV that does just this sort of thing. Here's a snap shot of other boards that have that part, maybe you have one as a donor.

I went mad with this issue months ago --- was the charger at fault, even though it was an original/genuine Apple one, but I had a magsafe 1->2 converter on it. Try with a known good working magsafe 2 charger for that model.

Try a donor bios just to check, but double check all your clock / BIOS lines continuities and pullups.

Funny end to the story - turns out that the SSD was originally set up on a 3437, and it works fine on that, but... the moron n00b at work here, when tried in the 00165 it came up with the crossed out circle, which is why I was getting confused, because to my understanding the crossed out circle...

I replaced the entire top-deck. It was certainly more expensive and it definitely wasn't brand-new (I wasn't expecting it to be, thankfully the client's own top-deck wasn't pristine either). The extra $150 likely saved me more than that in frustrations. Upside, I now have a spare top-deck...

CLK100M and continuity are the ones I'll have to check, everything else is appropriately present. Thanks.

U8005:9 was corroded out, cleaned up, restored boot / fan behaviour, still no SSD detect. At least though it's a step forward.

At least they'll be new, as opposed to "new".

"We just bought MS VisualStudio 2017 --- we're going to write apps and be riiiiich [how hard can it be?]!". Indeed, having tools is no good without the skills.

For sure, we all started out doing dodgy work, though there's a certain level of competence that typically needs to be achieved before we go "Okay, time to start offering this as a paid service", and that's the qualifier that's missing with too many businesses, especially when you see...

Good luck with that. Rossmann has stood tall on a mountain of easy money waving his "You can do it!" flag for so many to see. It's always the inevitable outcome, who can resist easy money?

I've modified the existing Windows BK-390A software that is being used on the current live streams to handle the different protocol used by the BK-393 (which seems overall to be a better meter). This hasn't yet been tested with a real meter, but at least it's a starting point (it works with the...

Thanks Duke, appreciate the clarification.

No Title Replacement deck finally arrived and installed. I do have one item I want to get clarified if possible Duke; Regarding the flipping up of the screen flex retainer / connector, Are you referring to the top retainer plate, or something else? ( as per shown in this picture ) After...

Would be nice to have a working reference. No donors of this model on hand, awaiting supply. I agree the TON pin voltage is a bit strange, unfortunately without a comparison on hand I'm unable to ascertain if that's normal or not for this model ( but yes, it's a flag in my mind ).

I did, same outcome. I would have liked to had access to a data sheet on this because it'd be interesting to see if the chip uses the TON pin as a status indicator too (ie, pulls it low to indicate a fault).

Waiting on replacement SMC from donors. Reflowing, and reballing produced no change.

Thank you.

Prior repair. Liquid damage. Arrived with no fan spin. Repairs to corrosion on U7600, replacing R7981, reconnecting trace between U7600 and C7981 (CPUVCCIOS0_EN) restored fan spin. No chime. No LCD_EN. I now have no PPVCORE_S0_CPU_REG or _AXG_REG out of U7400. U7400:1 EN (CPUIMVP_VR_ON) is...
