corona2222 Posted January 16, 2022 Report Share Posted January 16, 2022 (edited) Hi I've got another dead xbox the mobo is corroded by the clock cap. The previous owner tried to repair but components flaked off. I'm hoping I can add the missing components and get it working again with some help here. It's bad. It looks like 5 SMD transistors and 5 resistor or diodes are missing. serial and gfx chip (focus) suggest board is v1.4 according to https://www.informit.com/articles/article.aspx?p=367210&seqNum=2 The same area on v1.6 is very different so it would be a big help if anyone can photo the components on a v1.0 to 1.4 board thanks Edited January 16, 2022 by corona2222 Quote Link to comment Share on other sites More sharing options...
sweetdarkdestiny Posted January 16, 2022 Report Share Posted January 16, 2022 Resistors : R6F7 = 0 ohm ? Get no reading. R7G2 = 2940k ohm R7G1 = 1100k ohm R7G1 = 288 ohm R7F6 = 100k ohm R7F7 = 10k ohm R7F8 = 84k ohm R7F9 = 2000k ohm Pictures of the area : https://imgur.com/a/lYWnXeZ 2 Quote Link to comment Share on other sites More sharing options...
corona2222 Posted January 16, 2022 Author Report Share Posted January 16, 2022 (edited) thanks for supplying the values and pics I'll order and apply new components and go from there. I note the components silk screened Qxxx are transistors, and CRXXX are diode volt regulators I found a useful thread on reddit which concluded its the clock cap circuit and should boot without the three missing components. But when I switch xbox on, it flashes orange led, sometimes it flashes red and greed. but never gets further. (possibly im missing critical components for this circuit) Edited January 16, 2022 by corona2222 Quote Link to comment Share on other sites More sharing options...
JackedLynx Posted July 21, 2022 Report Share Posted July 21, 2022 I believe those components are just part of the clock circuit. I had an xbox once where they just fell off but it worked perfectly. I could be quite wrong though. Quote Link to comment Share on other sites More sharing options...
KaosEngineer Posted July 21, 2022 Report Share Posted July 21, 2022 Flashing orange is an indication that the System Management controller has detected an overheating condition. If the clock cap electrolyte reached the dual temperature sensor on the motherboard , the electrolyte may be causing the sensor to malfunction. The temperature sensor, an ADM1032, is the 8-pin surface mount chip located at located U7F1 edit: oops, U6F1. Clean the area around this chip and its supporting capacitors on the left side of it. You may have to remove the chip to get underneath it to clean any electrolyte residue and worst case replace the chip entirely. Edit: I originally posted the wrong location, U7F1, for the temperature sensor. The correct location is U6F1. 1 Quote Link to comment Share on other sites More sharing options...
