None of the CD3215's are producing 1V1_LDO I tested the CPU and PCH rails for shorts and did not find any as stated before.

No H2O on this board. When testing the usb power would cycle on / off I discovered one of the CD3215's was toast as a small hole was blown in it and it showed up quickly on thermal. Replaced it and it stopped the bounce but PP3v42 was a little low and the CD3215's were not talking to the...

Both speakers. Is digital sounding failure distortion speakers are good. voltage stable at U6410 Have replaced the DC-IN and ribbon (no change)

I have a 820-00165 that has digital audio distortion. The sound starts out ok then becomes digitally staticly garbled and fades out with some click click then will come back. Any ideas?

hello, I have a 820-00923-A I can not find any indication of liquid damage in any way. The Touch Bar display works and is normal but it does not respond to touch. I verified that the power rails to the touch bar are good. I have no clue as to the data and do not have a touchbar laying...

any way to modify the EFI I have all the programmers and a Medusa

DO these things exist? I have already found the ones for RAM. I have successfully changed the memory on a 4G board to 8G but I had to move a few resistors around before the board would see it. Where are the resistors that set the clock frequency.

usually PCH issues are pretty black and white. it's shorted it's usually really shorted. I use a water pick to spray soapy water under the BGA chips then clean with compressed air. I am not sure I would give up that easy on that board unless it's a 4g board or something of little value.

I purchased a used A1707 on eBay and am the victim of a bait and switch. The machine was listed as dead no power. I fixed the logic board 'which had no water damage" only to discover someone had also changed out the screen. They put a water damaged screen on it. So now I have a perfect machine...

I will take them. I have been building a battery pack for my golf cart and can use more. :) message me at 913.901.7626 I am in Kansas City Home of the Chiefs!

Good vendor list! This is a list of vendors that has sent me quality product at a fair price! _____________________________________________________________________________________________________ AliExpress LAP Electronics Co.,LTD. We have purchased 120 iPad 5th and 6th generation docks...

I have had repeated problems with Chinese chip vendors on AliExpress. If you are purchasing small quantities (1-5) you are better off buying them from Rossmann Repair Group! I wish Rossmann repair group offered special pricing for quantity purchasing as we would happily pay to have him filter...

Well the SMC is what I am after right now. I had to order the direct heating stencil and got abused over it. Cost about $20 Will be a few weeks before I come back to this one. I need to get a working board so I have a reference machine at least.

I was able to source a ISL9240 for $37 maybe these will start to be available? I now have one in stock!

My Medusa 3 broke. He sent me a new one. It started getting a error. The replacement works better than my original did so there must of been something wrong with it. I believe you need both. A regular programmer and a Medusa. Once in a while the Medusa would mess up a serial reprogram or...

Could this be a analog fail? Is the flickering random? I had a back light that was killing me. Under the scope the resistors looked ok. Nice solder blobs present. But I later discovered that it got under the resistor and released it from the pad even though it looked OK on top! First time...

Translated "In the initial phase the charging circuit receives only 5V from the charger. In this case, U7000 controls the Q7030 / 40 MOSFETs in Boost Converter configuration (step-up). Q1 is always closed (ON) and Q3 / 4 perform the SMPS switching functions; Q2 remains open (OFF), does not...

I am currently digging in the toy box trying to fix a junk board to replace a customer board that could not be fixed. This one had repair work done to the PP3V4 supply Now I do not get the 12V on the PPBus I get 1V I have already checked both Q730 and Q740 The 20v is present on Q730 but the...

I appreciate that input. It basically tells me that was a rabbit hole anyway. I decided enough was enough

After this repair I gave up. This board is not getting fixed. I will harvest it's processor to save a different board.
