hideehoo Posted August 25, 2020 Report Share Posted August 25, 2020 Got a version 1.0 that is flashing orange (high temp) immediately after power up. ADM1032 chip looks good and meters out fine for power and I2C bus connections, but when I throw a logic analyzer on the bus, it never returns a READ response. 1.958481000000000,I2C,Setup Write to ['152'] + NAK 1.958792500000000,I2C,Setup Write to ['152'] + NAK 1.959192000000000,I2C,Setup Write to ['152'] + NAK 1.959548000000000,I2C,Setup Write to ['152'] + NAK 1.960861500000000,I2C,Setup Write to ['152'] + NAK Compare that to a "good" box I have than returns both MB and CPU temps over and over during the boot process. 1.069577000000000,I2C,Setup Write to ['152'] + ACK 1.069807500000000,I2C,'1' + ACK 1.070072000000000,I2C,Setup Read to ['153'] + ACK 1.070300500000000,I2C,'24' + NAK 1.070584000000000,I2C,Setup Write to ['152'] + ACK 1.070815000000000,I2C,'0' + ACK 1.071078000000000,I2C,Setup Read to ['153'] + ACK 1.071306000000000,I2C,'23' + NAK Before I replace it, any other thoughts? Clock cap was still on the board, but actually looked pretty good (minimal leakage), and the ADM1032 and surrounding area has been cleaned several times with IPA.

SS_Dave Posted August 25, 2020 Report Share Posted August 25, 2020 I have read about that chip failing in the past. Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing. Quote Link to comment Share on other sites More sharing options...
KaosEngineer Posted August 25, 2020 Report Share Posted August 25, 2020 Yes, I've help someone repair their Xbox by having them install a new ADM1032 chip since the console instantly indicated an ovverheating condition with orange flashing eject ring, fan sped up to 100%, then shortly after that shutdown. After replacing the chip, all was good again. Edit: Another Xbox had a major clock cap leak that had reached the ADM1032 temp sensor chip. After cleaning the area around the chip especially between the pins with IPA, the overheating condition was cleared and the console started working as expected again. Both of these were remotely assisted repairs, I did not see all of the steps performed by the repairer. They both told me that their consoles were once again functional after everything they did.

hideehoo Posted August 27, 2020 Author Report Share Posted August 27, 2020 Pulled an ADM1032 off another fatally damaged board and this one fired right after replacement. So it looks the chip was bad even though visually there was no apparent issues. Quote Link to comment Share on other sites More sharing options...
