Hey all, got a 1.2 board here spitting Christmas lights at me (orange and green, power off, power on and repeat, red and green). It's not the disk drive or hard drive, I've tried alternative ones in their place. There is no modchip though I did remove one (Aladdin) as I was getting no signal from it beforehand. IDE cable is installed right way up. All caps look fine, clock cap has been removed. I don't see any broken tracing. I will repaste it as soon as some thermal paste comes in the mail. PSU looks fine to me too. Thoughts?
I recently bought a few faulty Xboxes yesterday and I want to try sort out this 1.1 which FRAGs. When I press eject it will often not open the disc tray, sometimes it will open quarter or half way or not close when it does open. I've tried 3 disc drives and they all have the same issue indicating a motherboard or possibly daughterboard problem. I have removed the clock capacitor which was only starting to leak. I've cleaned up what little leakage there was.
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.
