Aha, yeah but if you change CPU and its married set... (Including NOR flash)
Yes can be haven't got this situation yet.
Used dump_checker
Yes, this can happen sometimes with some problems. I had up to 11 at once.(10x 20 2120 + 21 3013)
It seems that specific reball problem and second one unsorted which ic AV/Hdmi. Is not in syscon errors pdf but M4j0r suggest to exchange one of these, I exchanged both and superslim started and running fine. I had only 2024 not together with 3034/44xx
Rsx 530xx, it seems for the damage character to rules3 end, maybe like that, later I will make sure from several different ps3, if from rules3 (initial) I read like this
That's in situ (in place). You need to read ohms off the board to know the state of the chip. Ohm test on board is dependent on more components having a solid connection (BGA, Tokins, MLCC bypass caps etc.). This is why the ohms often raise after a reball/reflow and thorough cleaning. Ohm test on the board is a qualitative test (may be useful, taken with a grain of salt). Ohm test off the board is a quantitative test (can diagnose a bad chip).
I agree, checking ohms is one of the things I often do besides checking the input voltage, this check is related to the input voltage to all ICs, if the ohms are not in accordance with normal, the input voltage will be disturbed, this ohm abnormality, then look for the cause, it could be part the power circuit or the ic itself
Yes, I agree, I also don't really care about ohms for certain areas, such as the tantalum ohm area or nec tokin, I often find ps3s that still function normally with a size of 1.2 ohms, especially for the cxd2971 which on average is smaller than the rsx. other. Some of the rsx cxd530xx are also small in ohm size but if it is 1 ohm or below it is usually bad, then for ohm the input voltage R5 is at least 60ohm size, I see it can still work, if it is below 60ohm it is not working well, like the ps3 will go blank or hang (dyn -001), the point is that ohm measurement is important, it has normal limits, from ohm measurement we can trace the problem part
Yes. After all this resistance would only be the area of the processor "core" to ground. There are many other things that can go wrong. 5 voltages not just 1.
Yes, we have seen for example when there is a problem between CELL BE and XDR RAM, the syscon will detect an error (XDR init failed). Even if it's not a YLOD. (GLOD).
If that means it's true, I'll try to fix it, I'll share the results later, still remind me of my question about 8-9 errors that occur in 1x reset (lost power), after reball cellbe turns blank, ps3 JTP-001
This is what I meant about AV/Hdmi ic 2024 only, when I have it on superslim. Just try exchange both AV/Hdmi ic and report back please. As you going to investigate those ic's you going to probably find missing signals between them (never had time to investigate)
Wow, thank you, I also mean a link for syscon, sorry for not following the rules
Actually it's related to cellbe and cellbe RAM, usually from cellbe RAM input power (12 ohms) which is not correct, if not from cellbe tin that is not good, cellbe reball is usually enough to fix it, not related to hdmi ic or av ic , the symptoms usually cause, every time the reset is held, you can't get 1 beep, the hdd indicator light doesn't flash, it's included in the rules4 category, but in the case I'm dealing with now it's worse, maybe because the cellbe is damaged or the RAM cellbe is damaged.
