On one of my Xboxes I have performed a recap (had some experience doing a NES and N64). I did the PSU first, with succes. Then the main PCB, but now the Xbox doesn't turn on. No LEDs, no video output. Only a slight crackling sound (almost not audible), but It's hard to pin point where te sound is coming from. Already tried reflowing the caps, but without any luck. Unfortunately I already threw away de caps, so can't change them back. All caps have the right orientation, clock cap has been removed and changed to a resistor.

Hey all, tl;dr Started to recap my 1.4, testing as I went. Board eventually started to 3 boot frag, cannot get it to recover. Did I break it beyond repair? So, I replaced the power supply that I accidentally blew up and all was good. Since I noticed that the caps by the CPU were bulging, I figured I might as well replace them before going any further so I ordered a full board cap kit from Console5. I've recapped other devices before, but I guess I must have been lucky because this gave me problems immediately. The multi-layer board and large ground planes made it extremely difficult to get caps out and clear the vias of left over solder. I don't have a hot air station or board pre-heater or anything like that which I'm sure would have made things much easier (one bedroom apartment with two people and a cat, space is at a premium). Since I was afraid I was doing damage to pads/internal board layers getting caps and solder out, I made sure to test the system after replacing every few caps. I decided not to do the whole board since I was having difficulty, and would stop after these last few. Well, after replacing those last few the system no longer boots. Here's what I'm getting: The first few times I tried booting, I got the 3 boots and FRAG. I reflowed some solder on questionable joints and got a solid green light, but no AV (seems to indicate inability to load a BIOS). Unplugged my modchip, but same issue. While not impossible, it seemed unlikely that both the onboard BIOS (this board was previously TSOPed) and the modchip BIOS would be corrupted so I felt I must have done too much board damage somewhere and maybe destroyed an internal trace or something. After going back and forth checking all the caps I replaced and even trying to solder from the top side to ensure a through-and-through connection (please, forgive me), I wound up at: 3 boot FRAG when modchip installed, but solid green no AV with modchip uninstalled. This led me to think that maybe there was an issue with the LPC though I hadn't touched that area since I originally installed the pin header 4 years ago. I reflowed those joints and moved the D0 wire from the Aladdin chip to a ground/screw hole on the board. Continuity between LPC pins and their respective traces check out fine on my multi meter. Now I get 3 boot frag with or without the modchip plugged in. Anyone have any advice or see anything in the pictures that I don't? Any help is appreciated.

All other caps are original.
