Asus X509JA płyta X409JA brak obrazu na HDMI

Witam, laptop asus X509JA, płyta główna X409JA rev.2.0. Laptop nie wyświetla obrazu przez gniazdo HDMI, nie sygnalizuje wykrycia podłączenia urządzenia. Sprawdziłem na innym systemie, bez zmian. Gniazdo nie wygląda na uszkodzone, chociaż klient twierdzi, że często podłączał przewód HDMI.
Pomiary, które wykonałem na włączonym laptopie z podpiętym przewodem hdmi:
Q4805:
D- 5,2V
S- 5,2V
G- 14V

Q4801:
D- 0V
S- 0V
G- 3,4V

Q4803:
D- 5V
S- 2,65V
G- 3,4V

Proszę o poradę co mierzyć dalej, czy może podstawić nowe gniazdo?

Hello!

Do you have a documentation for this board?

- Set your multimeter to the diode test mode and measure the voltage drops to ground on points marked as A, B, C, ... H (picture below). Measure with disconnected HDMI cable.
- Measure the voltage to ground on point J when the machine is turned on with the HDMI cable connected.

Hello, I have schematic only for this board, don't have boardview.
Voltages drops on all pins is 0,592V.
Voltage on J is 5,18V.

Are the video drivers installed successfully?
Does the machine respond to pressing the "F8" button (or "Fn" + "F8")?

If the schematic doesn't contain watermarks, please upload it on the forum (SCHEMATY LAPTOPÓW department).

Schematic is avaliable on the forum, I'm using it, maybe it is not the same, but looks like components nearby HDMI are the same.

Yes video drivers are reinstalled to the newest version. After Fn+F8 pressing I can select mirror, duplicate etc, but when I choose any option there is no change. Maybe I should replace HDMI port? It is used but very tight (it is strange, if it is much used should be loosed).

You need an HDMI cable with a cut end to check if the HDMI port is good or not.
If you don't have it, replace the HDMI port.

I replaced HDMI port and still no screen on HDMI. Do you have any ideas?
