PS5 Slim EDM-040 error 80D004FD

stetofix · May 5, 2026

What is the story of the console? It is unlikely that there are multiple different issues, unless liquid damaged/cockroach infested/training board for soldering.

The error C0810303 = HDMI IC problem/data line short circuit/power failure
Sequence step 206E = HDMI CECStart

I would check the HDMI port for correct readings:

Hi,

The console originally had a minor issue, but unfortunately a technician caused multiple short circuits in different areas of the board.

At this point, I believe the problem has been mostly narrowed down.

Based on the image you provided, all resistance readings appear normal and healthy. However, there is no voltage present on the HDMI pins, both in standby mode and Power on.

I’ve attached two additional images showing the current voltage readings on the board — they might help in identifying the exact fault location.

This are images for another board but should help.

The 1.3V at your HDMI pin 13 are too low. The question is, does the cap or one of the both diods are pulling the line down or is the HDMI chip itself bad.

I checked all the resistances around the HDMI IC, and they are all correct and match exactly the reference image I will attach.

After that, I thoroughly cleaned the surrounding area. The console then powered on, and the PlayStation logo appeared at 480p resolution, but shortly after that the screen goes black and the blue light starts blinking.

I’ve also attached the error log.

If the PS5 is stuck at 480p and a change to other resolutions (Option 2 in SafeMode) is not possibel, I would replace the HDMI chip.

After replacing the WiFi/BT module, the console now displays an image, but it is unstable and flickering.

Also, only one of the front USB ports is working — the other front port is not working, and the rear USB port is also not functioning.

Additionally, in recovery mode, no WiFi networks are detected, although they should normally appear.

Could this be related to the HDMI IC, or do you think it’s more likely another issue?

Also, just to mention — the installed chip is:
J20H100 REV 1.5

The original one, as far as I remember, was:
J20H100 REV 1.4

Could this revision difference be causing the problem?

It is possible that the NOR data isn't matching the WiFi module. I had some cases where after changing the NOR data the WiFi wasn't showing the WiFi MAC and therefore wasn't detecting any APs.

For solving this issue, I would use another BIOS dump.

Unstable, flickering output my best guess would be an issue with HDMI port/ connection to the HDMI cable.

Not working USB ports data lines are not a good. The data lines are SoC lines. You can check the filters at every USB port for continuity and hope the filters are bad. Otherwise the issue is SoC related.

After changing the board serial and matching the number on the motherboard with the BIOS dump, and also updating the number on the WiFi/BT module:

Now all USB Type-C ports are detected and working, and the console updated successfully. However, the same issue still remains — after the PlayStation logo appears, the screen goes black.

Also, the WiFi is still not showing, although the port itself has started working.

Could this still be related to the HDMI IC or another HDMI-related issue, or could it be something else?

I did the BISO file

Attached is your dump. I corrected the position and the CFI number and the other WiFi related MACs.
But I don't think it will change something. I would try the second dump without modifying it and see if the behavior of the WiFi is different.

The black screen after logo could be realted to the CEC pin 13 at HDMI port. I still think the voltage is to low.
If the handshake for CEC/HDCP fails, the screen stays black.

Thank you for following up and replying every time.

I flashed the BIOS using both dumps you attached, but the WiFi network still does not appear.

Also, I replaced the HDMI port, but the issue is still the same.

I measured Pin 13 on the HDMI port, and it reads 1.3V.

At this point, I think the HDMI, USB, and WiFi sections may all be related together somehow.

Which firmware version was the update you performed?

What is your diode mode and resistance readings on pin 13 (CEC) at the HDMI port?

The powerlines for USB, HDMI are switched on by southbridge and the controll and data lines from the WiFi module are also connected to the southbridge.

The update I performed was firmware version 10.01.

I also measured pin 13 (CEC) on the HDMI port:
- Diode mode reading: 695

Here is another dump from a edm-04x with FW 10.40.

Thank you. I tested this dump as well, but unfortunately the WiFi still does not appear and the same issue remains.

After the PlayStation logo, the screen goes black exactly like before.

Most EDM-040 boards come with the J20H104 and use only a 3.3V power rail.

However, some rarer boards come with both 1.8V and 3.3V power rails, similar to the one I have now with the J20H100.

Could it be possible that I need a BIOS dump specifically from a board that originally supports the J20H100?

Post automatically merged: May 8, 2026

Is it normal for both sides of this connector to be ground?

I checked continuity and both the inner center pin and the outer shield ring are connected to GND.

stetofix · May 9, 2026

The last BIOS I posted is from a edm-04x with J20H100 WiFi chip. So the BIOS should match your board.
