I just had the chance to test the DVD and it's almost dead and the HDD is completely dead. I guess the PSU problem send wrong voltage to everything. I have 2 questions I need help with: 1) The DVD drive is still recognized in ConfigMagic, but when I push Eject nothing happens, not even the classic blinking. Is there a way to fix it? 2) The HDD was connected using a startech SATA adapter that I guess should be also dead (considering the HDD) and the best approach is probably just discarding it. I wonder if it may be the cause of my whole issue, what do you think? I am asking because I am going to need a couple new adapters. Thanks in advance

Thanks@SS_Dave, I really appreciate the offering and your help. I think I have a eeprom.bin in my computer for that HDD. I have some final questions: 1) Should I try to fix the first PSU replacing the 47uf 25V? Or doesn't worth the effort? 2) What could cause the clicking noise I hear at the start? A transistor, IC? 3) I have another working xbox with the original CPU capacitors, should I replace those with the ones I soldered to this xbox?

@SS_Dave I got some new findings: A) Video cable detection still works, if it is disconnected the console flashes green/orange after 3rd attempt B) I powered the console without fan and noticed a strong "click" sound during each power on attempt (3 times), I got the impression it is around the MCPX X3 chip. I can feel the smell if I leave the console on during the christmas lights phase. C) Also, the MCPX X3 gets hot quickly. I can't maintain my finger on top of it during the power attempts sequence. D) minebea PSU measures (with mainboard) Blue (POWOK) 3.31V White 2.84V Brown 3.21V Orange 3.31V Red 5.12V Yellow 12.34V

I though the smell could be related to the fan and I disconnected the console fan, BUT forgot to disconnect the GPU fan. I am powering the console without HDD nor DVD Edit: New findings: A) Video cable detection still works, if it is disconnected the console flashes green/orange after 3rd attempt B) I powered the console without fan and noticed a strong "click" sound during each power on attempt (3 times), I got the impression it is around the MCPX X3 chip.

Is it possible that mainboard get worst because of turning it on constantly with this failure? Is there a way to test shorted capacitors in the pcb, without desoldering?

@SS_Dave I connected the minebea and tried to turn it on, but still the same result: reboot x3 and christmas lights. I need help with the following: 1) do you want to measure voltages with the console turned on, right? 2) when I turned the console on, there was still a burned electronic smell, that makes me worry (it dissipates a couple seconds after I turn it off). IS it safe for me to measure the voltages meanwhile? I mean, could something explode suddenly if there is a short??

@SS_Dave this xbox was never hard modded. I soft modded it just the past year using Rocky5 softmod. The only soldering made in this board was for: 1) removing the clock capacitor 2) replacing the CPU capacitors I just measured the voltages of the new delta PSU when its powered on: Blue <nothing> Brown 3.28V Orange 3.31V Red 5.33V Yellow 10.80V I gonna measure the minebea and let you know. Edit: minebea PSU measures Blue (POWOK) 3.27V Brown 3.23V Orange 3.28V Red 5.17V Yellow 11.43V Looks like the delta is failing right? Could it be my mainboard that damage it?

Some images: https://imgur.com/a/aw4d0Ml There are some images of the OLD PSU, maybe it helps pointing to what could got damaged in the mainboard. I think the FRAG started as soon as the PSU capacitor exploded, I am not completely sure because I hurry to turn it off. At least I am certain that when I changed the PSU, but haven't replaced the CPU capacitors yet, everytime I power on the console it restarted 3x and then displayed red and green lights 50/50 fast, PLUS a strong smell. Now that I replaced the CPU capacitors there is no longer a strong smell, could that be related to the old CPU capacitors? And currently, the "light" smell starts everytime I turn on the console, it is not longer a big smell, could I still have a small capacitor dying or about to explode? Please let me know what else can I attempt, I have a cheap multimeter if it helps in something.

Let me share some context: The past year, I read about the clock capacitor, so I decided to open my xbox to check the clock capacitor status and I found there was some leakage, but fortunatelly it didn't corroded other components nor traces. So I removed the clock capacitor and cleaned the area with isopropyl alcohol. Then proceeded to softmod the console with Rocky5 tools and I also updated the harddrive to a 2TB SATA HDD. Then I played almost all Rally Sport Challenge 2 cups (except the last one) to test it and after that I moved the console to the living room. Another day, I started the console to continue playing and, as soon as I started it, I heard a strong crack inside the console and some burned electronic smell, so I turned it off. Then I opened the console and I found a small tube moving around, so I started looking for its original place until I found it was one of the PSU capacitors, the one rated as 25V 47uf in a delta PSU. Then I ordered a couple of new PSUs from ebay, a delta and a minebea. As soon as they arrived, I replaced mine with the Delta one and the console can be powered on, but there was a strong burned electronic smell, so I quickly turned it off. By looking at the CPU capactitors, there was some brownish color, so I changed the 5x 1500uf 6.3v by 3x 3300uf 6.3v Panasonic FM, then turned the console on again and it was FRAGed and the smell it's not longer strong, BUT I still can smell a light "funny smell", this time it smells like "new" electronic. Please help me to throubleshoot this issue, I really would like to repair this xbox as it is the one I used 20 years ago. If you need pictures of anything please let me know.
