Re: PS4 with BLOD - Getting UART enabled ?
What hot air station are you using? What airflow and temps also? Are you using a nozzle to direct the heat?
All of these will have an affect on how well you can get heat into the board, not to mention 480*c on a cheap station is not the same as 480*c on a Quick, Weller or similar.
A pre-heater will always help, but I would go for the PUHUI T8280 over what you have posted above (the PUHUI can usually be picked up cheap 2nd hand), it is large enough to heat up the full board so then you only need a little bit of...

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020
That grey component is an inductor (coil of wire) it will always show as short on a DMM, it is high impedance to AC and low impedance to DC, hence they use them on the output of DC-DC converters to reduce the ripple on the output along with the help of some decoupling capacitors.
I think you need to go back to basics here. If you have a short on the 12V rail (PSU is entering current limiting mode) then you need to figure out what on that line is drawing so much current.
It could be...Leave a comment:

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020
So if you inject 12V, current limited to 1A on the main 12V power rail the PSU kicks into constant current mode and providers 4.35V @ 1A? In other words 4.35W of power.
You have a short somewhere if your PSU kicks into constant current mode. As you know the board should draw 300mA then drop down again when 12V is applied if it is trying to draw over 1A and being current limited by the PSU it indicates either the 12V rail or something that feeds off of it is shorted or partially shorted.
I would get the...Last edited by Mario875; 07-20-2023, 09:55 AM.Leave a comment:

Re: PS5 black screen with sound
Check the common mode filters between the HDMI IC and the HDMI port, they should be dead short from one side to the other but not diagonally between lines.
If all is good with them then next step for me would be to get out the oscilloscope and monitor the signals going into the HDMI IC (is the APU providing a video signal?) and if it is then monitor the output of the HDMI IC (is the IC outputting a video signal?) and try to narrow down where the issue is occurring.
Can you also provide a hi-res image of the HDMI IC, its surroundings...Last edited by Mario875; 07-15-2023, 06:31 AM.Leave a comment:

Re: Xbox Series X shuts off after ~6 seconds
Don’t know why people are debating this if it’s a Series X…they all came with NVME type SSDs (in a non-commercially available size).Leave a comment:

Re: PS5 CFI-1016A DISK shuts down only when playing ps4 games error ce-108262-9
According the the PlayStation website this error code means "[B]There may be a problem reading the system software or application data[/B]"
So first step would be a total format of the console and start fresh with install of the latest SW, if it still happens then I would be looking at the SSD / SSD Controller, because other than that it is likely to be something with the APU itself where certain specific PS4 cores / features are utilised within the APU and the pipeline is stalling...Leave a comment:

Re: PS5 CFI-1016A DISK shuts down only when playing ps4 games error ce-108262-9
Does this happen on all PS4 games or are you testing the same game every time? If you are only testing with 1 game, try another one and see if its any better / worse / different.
Which game(s) are you trying to run?Leave a comment:

Re: varistor indentify xbox one s
Not sure why you packed it as a RAR file to upload? However first port of call would be to clean up the PCB and inspect for damage, is it even re-usable after such a failure? The neutral wire especially looks like its burnt through the insulation, but might just be the photo.
Next would be to know what happened to cause that damage, clearly a surge event, but what was it, lightning strike or something else? Once you have confirmed the PSU is repairable and the issue that caused the damage won't re-occur as soon as you plug it back in...Last edited by Mario875; 06-14-2023, 03:08 AM.Leave a comment:

Re: PS5 BLOD- CFI-1115A Disc Version- Board= EDM-020
Give the video below a watch, it’s 1h long but pay attention to the console symptoms (sometimes works but with no Wi-Fi, sometimes blue light, sometimes 3 beeps) and pay attention to what he says about the 8mA current draw around 30 mins into the video and again the 10mA current draw (after replacing the damaged part) like you are seeing due to the 32kHz oscillator not running what he ultimately finds out the issue is (southbridge!).
Not 100% identical to your issues but there are obvious similarities…I...Leave a comment:

Re: 0.01 AmP Short on PS5 motherboard
That’s not a short, 10mA draw is just what the board it taking but it’s not right, looks like it is stuck at the POST boot. It should increase to around 300mA when you apply power then settle down to around 70mA of I’m not mistaken.
The only info you have here is that the power on sequence is not happening if it just takes 10mA as soon as you apply 12V And hold there.
You need to do more fault finding, check all standby voltages, check for shorts on power rails (what is the actual resistance from the...Leave a comment:

Re: playstation 5 digital firmware dump
Thanks! I can see the info at 001C7230, but on 001C7200 & 001C7210 there appears to be some kind of string, is that the disc drive key?
Or if not, can you confirm the location of the disc drive key?
EDIT: Looks like the .bins I have are as follows:
[LIST=1][*]CFI-1015A[*]CFI-1016A[*]CFI-1016A (2nd one)[*]CFI-1016A (3rd one)[*]CFI-1016A (4th one!!)[*]CFI-1016B[*]CFI-1116B[/LIST]
So that's 5x disc edition ones and 2x digital edition ones.

Re: playstation 5 digital firmware dump
So, I have some BIOS files, but how can you confirm which console they are from? I assume these are encrypted and need to be reversed some kind of XOR value and possibly byte swapping, but I have no idea where in the hex to start looking.
Anyone got any info on this?Leave a comment:

Re: electronic load for PSU testing
They work well for PSU testing if used correctly, but be careful, I have seen an instance on a power supply that was being tested from an industrial device where the load was set to 200W BEFORE the PSU was powered on, then as soon as the PSU turned on the load was immediately asking for 200W as the output voltage is still rising (200W @ 1V = 200A!!) and it essentially over loaded the PSU resulting in catastrophic failure, a big bang and black ash.
Admittedly this PSU on question has a startup circuit which failed dead short and caused...Leave a comment:

Re: Ps4 slim SAF 004 burned after a lightning strikes
You might end up needing a thermal camera and do some voltage injection to find where the short is on that power rail.
However if I had to place bets I would look at the HDMI encoder, check the caps around that IC and see if they are shorted as well, if so, remove the encoder and check if the short is still there.Leave a comment:
