CrossfireCam Posted February 1, 2023 Report Share Posted February 1, 2023 Hi guys, I've got a mate who owns an OG Xbox (Xbox #1). Unfortunately, Xbox #1 had corrosion on the motherboard from a leaked capacitor. So I'd given up until hearing another friend had a broken OG Xbox (Xbox #2). I found in my research that swapping the hard drive over wouldn't be possible, so my mate would lose his saved games. But accepting that, I took Xbox #2 to repair, and found that it was experiencing a problem. Fan spin while holding down the power button, but the console would stop responding once the button was let go. I proceeded to troubleshoot, and found a suggestion that the 5 large capacitors near the CPU should be replaced (if there's fan spin but nothing else). So I bought new ones and did just that, but the console is still unresponsive besides fan spin. I've checked all over for evidence of corrosion or burst capacitors, but can't determine what's wrong. I'm hoping that posting pictures here of the motherboard from all angles will yield some good advice for how to continue. I'd appreciate any ideas to help my mate out. https://imgur.com/a/9pySTGX Unfortunately using Xbox #1's PSU in Xbox #2 yields no fan spin at all. I haven't bothered posting Xbox #1's pictures because I assume the motherboard is toast due to the corrosion, and saved games can't easily be salvaged (I saw something about extracting the key from the CPU using some tool or other; that's too much for me).

KaosEngineer Posted February 1, 2023 Report Share Posted February 1, 2023 What versions are these Xbox's? Note: I see that Xbox #2 is a v1.6 model. Power supplies cannot be swapped between all models. There are 3 different types of Xbox power supply units. v1.0-1.1, v1.2-1.4 and v1.6 compatible. Even though v1.2-1.4 models have the same motherboard connector as v1.6 models they are NOT interchangeable. Quote Link to comment Share on other sites More sharing options...

Even though v1.2-1.4 models have the same motherboard connector as v1.6 models they are NOT interchangeable. Xbox #1 is a v1.6b (Hynix RAM, Xclaibur CPU), while Xbox #2 is a v1.4 or v1.5. I checked here https://www.youtube.com/watch?v=Vxs2o3u22K4 Xbox #1 is likely a lost cause. I've got a pic of the corrosion here: https://imgur.com/F8bUVkK. It looks like a corroded clock capacitor as warned about in this vid https://www.youtube.com/watch?v=uy-btflp0-U. If only my mate had seen it sooner. Maybe the fix is easier than I expect? I'd like input on how bad the corrosion looks. I only have a standard soldering iron. Xbox #2 I already tried replacing the 5 CPU capacitors but as previously stated that didn't work. Are there any suggestions for what to try next for Xbox #2? If either Xbox doesn't appear salvageable, my mate is considering getting a 360 to replace it.

MadMartigan Posted February 7, 2023 Report Share Posted February 7, 2023 I would clean the clock cap area first thing. No telling what’s sitting in that mess. Quote Link to comment Share on other sites More sharing options...

Looks like you may have discovered some new form of fungus that feeds on PCBs. 2 Quote Link to comment Share on other sites More sharing options...
starbreaker Posted March 3, 2023 Report Share Posted March 3, 2023 Yes, clean the clock cap area up. See how bad the damage is. Quote Link to comment Share on other sites More sharing options...

I wanna see what got eaten by the unidentified form of life that was discovered. What are PCBs made of anyway? Fiberglass? Quote Link to comment Share on other sites More sharing options...
CrossfireCam Posted March 12, 2023 Author Report Share Posted March 12, 2023 I removed the clock cap on Xbox #1. Two of the components fell off (Q7G2 & R7G3 I believe), and I couldn't replace them. My soldering iron was too large and the solder wouldn't attach to the pad anyway. Xbox #2 is new enough that I hear removing the clock cap is unnecessary, so I've broken the news to my mates, and I'll give the parts to an OG Xbox repair person in the local area sometime, for them to make better use of. There's no guarantee that replacing any given component in either Xbox will fix their problem (without having the skills to trace the problem correctly anyway, which I don't possess).
