I have a slim that doesn't do much you try turning it on it beeps and that is about it the error code is 0022 and By what I have read thats is related to the hana chip/.

I posted a pic of what my chip looks like and it has a resistor that is circled in red that i am not sure should be there most the pic and other slim I have seen doesn't have it.

Hey ... i could be wrong. But I think with the 0022 you are actually having issues with the combination Main Chip.

In the Slims - I believe the GPU/CPU are one chip. If it were my slim 360 - I would Reball that chip & maybe Reball the HANa too

If you need a Reball service - Myself and others on this site do this work. Its a great repair.

If the term Reball is new to you - go to Youtube - search and watch good video on 'Xbox 360 Reball'

So about the code - if anyone can prove my wrong - if things are different for the Slim - Let me know

The CPU/GPU on the Slim consoles is indeed combined into one chip....you are going to have to pay to have one of us on this site or a local repair shop to have a complete reball done....the slim will show a red dot before any damage to the system can be done unlike the old 360s..if i can be of any further help i can be contacted via
