I have a jasper that is rgh3. I did it about a year and a half ago and was working fine. I put it away for a while during a move and subsequently used my slim for gaming. However I went to turn it on today and I have no power to the system at all. I tried two different power supplies and both seem to be fine (have the yellow/orange/ button lit):

Here's what I have:
-5v standby power, won't even tease start at all though
-all capacitors look fine, there is no bulging or leaking
-there is continuity with the rgh wires
-Took it out of the shielding to see if there was a short occurring.
-Tried multiple power supplies
-Tried a different rf module

Any thing to look at that may be causing a powerless motherboard?

Connect the power cable and check for continuity in the 5v and 12v lines to ground.

Are you able to connect your NAND and try to dump it?

In my adventures with my XBOX 360, I somehow "lost it" to a supposed brick, and one of the tests I did was trying to read the NAND.

If the console has been off for a while, it might help to clean it with some IPA alcohol. You might be missing some corrosion in a trace?

Your better chance is to spend some quality time with the motherboard and a multimeter.

Also, sometimes, some more knowledgeable people can help if pictures are presented for perusal.

Have you tried powering on from the eject button. It should boot to Xell if it RGH'ed. If that works then it is in the power button module.
I have tried on the reset. I also tried two alternative modules to see if that was the case and there was nothing. A buddy and I have spent some time with the board and multi meter the other day, but hope to have more time this weekend.

I'll post some pictures today. I'll see about getting a nand dump just to verify if power is getting to where it needs to be there. The RGH wires seem solid as well.

    Pretty cool, my DAW (MPC 2,0) has whats called "Stem Separation". It will take any sample and split the sample into different tracks and filter sounds, example: Will separate to 4 tracks, 1 for bass, 1 for vocals, 1 for drums, 1 for rest. https://www.akaipro.com/stems.html
