pin 2 of D9701 = 28.90V Ya C9797/99 it's ok. no corrosion on there. i will check all resistors. but all seems ok. thanks

Sorry, my mistake. i mean pin_21_U9701 to pin1_C9796. was corroded.

Hey , Liquid damage, Area U9701 and U7100.. This one already works but backlight appear slowly and with DIM backlight like photo show. Already replace U9701, D9701, R9840, fix trace pin_24 _U9701 to pin1_C9796. LCD connector looks well and already did 3 PRAM. Any suggestion ? thanks

Hey, after check all inputs and pull up resistors and compare with a working board i reached the conclusion that SMC have problems. Replace again SMC and Now its working. But the main problem remains... "This machine when i turn it off normally in osx and after that if i want to turn it on...

Hey guys, Returning to this one, now i don't have green light and PPBUS = 12.28V Already replace 2 times SMC and U7100. SMBUS_SMC_5_G3_SCL - 0.495 - Voltage = 3.4V SMBUS_SMC_5_G3_SDA - 0.495 - Voltage 3.4V SMC_RESET_L - 3.38V SYS_ONEWIRE 3.39V ADAPTER_SENSE - 3.39V SMC_BC_ACOK_VCC -...

OK, I Already moved the ram chips one by one with flux and the machine come to life. Let's see how much time it is during! Thanks

Hello, This motherboard came with a little corrosion close to u7501, properly c7537, r7521, c7536. But i think that corrosion it's not the main problem. I found F7140 opened, and i noticed PPBUS it's shorted! when i apply 1V on PPB?S the PCH get's real hot more than usualy. I noticed to...

Hey, No liquid or components knock off! when i plug the charger the motherboard beep 3x! Already unplug all connectors trackpad, keyboard, etc. Same history no changes. any ideas ? Can't find nothing related on posts... thanks

First thing i did its try a new DC in! while i was check the voltages i noticed that voltage on pin 2 was wrong. Common R7005 problem. some times we look for the hard things and forget the basics! Thank you Mr.while i was check the voltages i noticed that voltage on pin 2 was wrong...

Hey, This one, no liquid and no signs of corrosion or components knock out! I don't have green light! PPBUS - 1.3V PP3V4S_G3H -3.5V SMC_BC_ACOK - 0V resistance 27/28 : 21 ohm resistance 17/18 : 3.4 ohm already replace U7000 2 times same history.. The motherboard already turn on 2 times...

already did the 3 PRAM reset.. no changes!

Hello, I already tested without keyboard using power pads and removed C4810 to discard leakage.. Same behavior.. Do you have more ideas for this one? I already have medusa.

Hey, Working on 820 3662, no signs of liquid or something like that. I was the first to open it and the board it's very clean! This machine when i turn it off normally in osx and after that if i want to turn it on, the machine don't turn on... it's necessary to remove the battery, press for...

I'm interested if you still have! already pm to you!

Hey Bios working perfectly! no freezing, all seems OK! If i could get into a hole i would! But for me yesterday i learn a lesson! thank you one more time Mr.Vali!

i will try the bios! and i will commend! Thank you

thank you!!!!

Hey 2informaticos, sorry for boring you but i need your help to build a bios! Please, can you try to build a new one from my old bios?? https://drive.google.com/file/d/1uuj...ew?usp=sharing i wont bore you anymore related to Bios because i already bought a medusa 2! But only next week...

Thank you Mr.Vali! My doubt is were is Fsys area on this bios. in another post you say: " change Fsys area (Fsys <--> $SVS marking strings)" But in this bios i cant find ?SVS ... But i already decided that i will buy a medusa from Ccmizapper! I don't want take more time from you and me...
