1.6 Xbox FRAG after capacitor replacement. Help needed.

[Jawannaman]

So I have a 1.6 Xbox that I softmodded with UnleashX few years ago and it's been great. Last week I was playing it just fine, got tired and turned it off for the night. Couple days later it wouldn't boot up at all, id hit the power button and it would attempt to boot for like half second then turn off. Opened it up to see 5 capacitors bulging on the bottom right of the motherboard under the CPU/GPU area. So I ordered replacement caps and installed them and now I'm getting a FRAG with no video output. I've been trying to diagnose for few days. I've swapped out the power supply with known working 1.6 PSU, I've tried swapping back to my original HDD from before the softmod all to no help. I've checked voltages at PSU connector, my issue seems to be the inductor (L2F1) isn't getting the 1.7vdc it should be getting from researching on this site. I've checked the transistor next to the L2F1 and getting 5vdc on one side and 1.7vdc on the other. I've checked the transistor (Q7C2) and getting 3.3vdc at the collector. Any help would be appreciated as I'd hate to make it a parts xbox thanks.

 

Edit: I mightve connected a older revision PSU (1.1-1.4v) without noticing in a attempt to rule out power supply. But have since checked two different 1.6v PSU with no effect.

It's hard to tell from your picture but, are you are certain that they are the same value as the ones that came out.

6.3v 3300uf?

@JawannamanAnd that the polarity is correct? Stupid question, but hey, I've done it.

from what I can see, the polarity on all 5 looks correct
