Undocumented SYSCON error due to faulty HDMI chip?

[Yanitee]

I had error 2120, decided to reflow after my reball to make sure all connections we're made. And I got 0xa0201b02, which I have never seen be documented anywhere! I am going to swap out my HDMI chip with a supposedly working one, see if that fixes it. I am quite curious if anyone else has gotten this error.

Forgot to mention that my current HDMI chip is confirmed to not be working. But this error still confuses me

00000000 A0201B02 FFFFFFFF RSX VRAM FAIL - Faulty vrams (core would read a 0.2 ohm reading)

This one is from my first rework try. The rsx is dead and probably the cell too lol. If you reballed a HDMI encoder it means the console was delivering video at least via A/V, and if the console doesn't boot now, with that error, could be related to some kind of bga merge under the encoder, shorting the rsx.

The rsx is probably dead now, yes, it was my first attempt at a reball and I also had to do 2 trace repairs, lol. Thanks for responding tho, I posted this just because I was curious of anyone else had this error, not in hopes of resolving it.

COK-002 / E01 / Bxx board behavior with RSX removed:

SSM signature:
[SSM] state: 0103 -> 0303
[SSM] PowSeq Fail : Detected !
[SSM] state: 0303 -> 0700

Note:
On COK-002, this can be normal missing-RSX behavior. Do not automatically diagnose board-side VRM failure from this alone.

0xA0201B02

I did some testing here cause i ran into this error you get this with bad rsx or without an rsx at all only on COK-002

the COK-001 is diffrent with a removed RSX

I see this post is a bit old but i was messing aroudn and got this 0xA0201B02 that is what i discovered... can be the VRAM circuit/net as well also got thsi wirht a fine VRAM measurement to and all rsx points actual connected to board y case vcore wasa bit low and vcore net was bad from NEC short so anyways its a odd duck one

Reflow the PowerSeq makes ya think short but with RSX off same thing so anyways jsut my 2 cents messing with that error resolved repalced RSX and 1 NEC pulling the vcore way down everntualy after good boot all NECs went...
