I tried the two bios, but it still doesn't seem to work, the fan increases to maximum speed when first turned on, then it restarts and always gives a black screen, you can encounter problems with the CPU

thanks, already tried with isopro alcohol. blown with air etc, nothing, from what I read there is a contact in the connector that without the jack inserted must be closed to enable the internal speakers, if open the digital output with the red light remains active, I was thinking of bridging these two contacts, do you know which ones are on the connector?...Leave a comment:

IMAC A1418 no internal audio
hi, i have this imac that does not emit sound from the internal speakers, when i turn it on i hear the boing, but once in the system it has no audio from the internal speakers,

i disconnected the headphone jack plate on the motherboard but it does not solve the situation, do i have to replace it? ic audio?... -

here SMBUS_SMC_3_SDA 3.3 v SMBUS_SMC_3_SCL 3.3 v all connected track, battery etc, when turned on there is no rotation of the fans, I ran the diagnostics and it is without errors, the fans started to turn first the right one then the left one, but when I turn it on the fans remain stopped, I don't think it's normal, can I check something else? thanks...Leave a comment:

I carry out measurements and update, I noticed that the SMBUS_SMC_3_SCL and SMBUS_SMC_3_SDA line between u5860 and u5850 measure 8 ohm and 3 ohm on the common points, if I disconnect the flat trackpad the fans start to spin quickly and the Mac slows, if I connect the fan remain still...Leave a comment:

I checked the connections again and they all seem correct, A0 to ground, A1 not connected, I recovered the spare part from a 820-01949 board, looking at the diagram this is U5850 TMP461-S, could this be the problem? The diagram instead of my sensor gives me TMP461 without the final s...Leave a comment:

mac 1706 fan not working damage U5860
Hi everyone, I have this Mac that had flaxgate problems, it was repaired, I noticed that the fans were running at maximum, I inspected and found the u 5860 torn away, recovered the chip on another main, I rebuilt the tracks, but now the fans don't turn really, if I unsolder it the fans go to max and the Mac is very slow, could I bypass this sensor? I attach the diagram+brd thanks...
