i accidentally remove some capacitor(resistor) of my logic board after i try mount cpu brackets on mac . i just see 1 and 2 led on, no chime its just going loop . i have 1x8 gb ram installed on bottom slot. please help i just buy screen and now this happen :(… @danj Hi Dan, A bit off topic I need some help. I did the same mistake on my Mid 2015 27” iMac 5K. According to schematic I need a c2340 2.2uf 20% 6.3v cerm 402/LF I search on that site but I can’t find exactly as is written. I can’t find “LF"on the end. e.g. “Multilayer Ceramic Capacitors MLCC - SMD/SMT 2.2UF 6.3V 20% 0402” from MURATA. is this good?
Here’s an image with the damaged parts marked
So you’ll need: From the Top C2340 - 2.2UF 20% 6.3V CERM 402-LFC2352 - 1 UF 10% 10V X5R 402C2351 - 1 UF 10% 10V X5R 402C2350 - 1 UF 10% 10V X5R 402 R-Pad DamagedC2453 - 1 UF 10% 10V X5R 40C2640 - 2.2UF 20% 6.3V CERM 402-LFR2641 - 10K 5% 1/16W MF-LF 402R2640 - 10K 5% 1/16W MF-LF 402C2653 - 1 UF 10% 10V X5R 402 L-Pad DamagedC2650 - 1 UF 10% 10V X5R 402 Heres the number needed of each value: Capacitors 6 - 1 UF 10% 10V X5R 4022 - 2.2UF 20% 6.3V CERM 402-LF Resistors 2 - 10K 5% 1/16W MF-LF 402
