Hello, I was wondering if anyone could help me with what I believe to be a hardware repair for my Xbox 360 S

The problem is that when I press the power button is just makes a small beeping noise and doesn't actually turn on. I looked up the usual issues but couldn't seem to solve the problem. I have replace both the ribbon cable on the face plate as well as the rf module. I also checked all the pins on the different ports (usb, hdmi, ect) and didn't notice any obvious bent pins or shorts. I also took a general took the whole board and didn't see any spilled "gunk" or corrosion. For all my tests I also took out the internal hard drive to remove that as a factor.

Any help would be appreciated, thanks!

Is this a corona motherboard with a 4gb nand? If it's then the 4gb chip may have died which is a pretty common problem on those 4gb coronas. The proper repair in that case would be to replace or downgrade the 4gb nand to 16mb. If it's not a 4gb corona, then you may have a bad XCGPU or something else.

Sorry I'm not such an expert as this stuff so I'm not entirely sure.
I did notice that on the board it has the
hana x802478-003 chip which I believe relates to the nand with the limited research I did but I'm not sure if that gives over all the information needed.
If not are you able to tell me how to tell?

Thanks a million!

It must be a trinity since you have a HANA chip. Coronas don't have those. I would assume the problem is related to the XCGPU or something else. It's usually the XCGPU that goes though.

No problem and hopefully this helped.

Do you know if there's a way to tell if it's defective? It's just that buying part after part and hoping that that's the issue starts to add up...

It's hard to tell with no power because usually hardware problems give off RROD, but in some cases you get no power too. It's something for a professional to diagnose. I recommend Octal450 if anyone but with all honesty, the repair and diagnosis will probably cost more than the unit is worth.

What you can also try is powering it with a wired controller. This will eliminate the question of whether your faceplate / rol board is at fault, despite those already being replaced.

Good luck!

Did you try powering it on with the controller before you started messing with this? Also what color does the power brick led show before you try to turn it on or when you hear the beep? If the console beeps its receiving power. But it could be as simple as a bad power supply or bad capacitor. If you changed the ribbon it's possible you could of just shorted out the ribbon. Pics will help. Always check one thing at a time. Also I doubt it's anything to do with the cpu/gpu or Hana chip Check the power supply first. Check everything I said. Make sure the power brick is also plugged in correctly
