  1. Topic title should contain: the device's manufacturer, full model and the brief description of problem.
  2. Topic message should contain: the PCB marking code (required in case of hardware repairs), an extended description of problem, things you have checked/replaced/measured, your conclusions and the question. If you are not able to find the PCB marking code, please read THIS TOPIC. If you still cannot locate the PCB markings, please upload a clean, both-side photos of the mainboard - it is required to remove any films, modules or brackets possibly covering these markings.
  3. Before posting a new topic please read all topics in TRAININGS subforum and make a preliminary diagnostic based on the content of those trainings.
  4. Uploading of any complete schematics, BIOS / firmware files or any other kind of documentation, or linking to 3rd party websites with such files, is STRICTLY PROHIBITED. You can only upload the small portion of documentation or, link to BIOS file on UNVERIFIED BIOS FILES subforum, which simplifies the diagnostics/repair. You are not allowed to upload more then one complete page of instruction/schematic per single topic. The file you upload must not contain any watermarks, "confidential" markings, links or email addresses and cannot be password-protected.
  5. It is only permitted to describe one faulty device per single topic - you should always open a new topic for each subsequent device.
  6. Requesting of the full schematics, BoardView files, BIOS files or any other kind of documentation is NOT ALLOWED in this subforum. If you need to ask for any of these, you should open a new topic in DOCUMENTATION/BIOS REQUEST subforum.

Konsola Sony PS5
Płyta : EDM-010 100889021
Konsola jest prawdopodobnie po zawarciu na tylnych gniazdach USB.

Konsola włącza się, ale nie ma obrazu ani dźwięku. Wygląda to tak jak gdyby konsola
normalnie startowała z niebieskiego światła robi się białe ale brak obrazu. Próbowałem wejść w safe mode ale wygląda na to, że nie wchodzi bo mimo iż słyszę drugi (bip) to światło nie zmienia się z białego w niebieskie.

Hello!

Measure the resistances to ground on all pins of both USB ports.

I removed USB potrs
From time to time the screen blinking and shows an "ants"if You known what I mean.
I have resistance in Mega Ochms on the USB pins

How about the resistance measurements?

It looks like the signal goes through HDMI because i can see TV reaction but no displaying ;-(

See coils marked at the picture all of them have low resistance around 0.7Ohm. Is this normal ? On the second side of the board same story

Such a low resistance is not normal.
What is the voltage to ground on these coils when the console is turned on?

I am sorry I made a mistake in writeing the resistance of those coils is 0.7 Ohm not 0.07 Ohm
On those coils is 0.94V

It seems better.

Measure the voltages to ground on all coils, when the console is turned on.

Yes, I understand, but how about the voltages on all other coils on the board?

#11 Re: Sony PS5 - Brak obrazu i dzwięku


by SPIOH1979 10 December 2021, 11:07
Maybe the USB ports should be in the circuit ?
It is very hard to measure another coils. they are covered by metal shield from the side of a heatsink
I will need to power a motherboard with out cooling.
Maybe it is BIOS problem it looks like the console work but doesn't display goes in to a sleep mode and wake up too.
I repalced a HDMI port just in case too.

I don't understand what you mean by that.

Set your multimeter to the diode test mode and measure the voltage drops to ground on pins 1, 3, 4, 6, 7, 9, 10, 12, 13 of HDMI connector.

To są jakieś kpiny. Jeśli autor wątku ma zamiar w ten sposób odpowiadać na pytania, to jest to zwyczajnie brak szacunku do społeczności forum i strata cennego czasu.

Dopiero po 14 postach dowiedzieliśmy się, jakie są napięcia na cewkach przetwornic (gwoli uzupełnienia, na układy BGA można na czas pomiarów zamontować małe radiatory ze starych komputerów, aby rdzenie układów się nie przegrzewały i nie fałszowały pomiarów). Nadal jednak - pomimo dwukrotnej prośby - nie doczekaliśmy się konkretnych wyników pomiarów na liniach sygnałowych gniazd USB. To, że masz wyniki w megaomach, nie jest żadną informacją, bo wystarczy, że na jednej parze masz 1MΩ a na drugiej 7MΩ i to już oznacza, że coś jest nie tak. Ty - jako posiadacz płyty, którą próbujemy pomóc Ci naprawić - masz wykonywać konkretne pomiary i przedstawiać konkretne wyniki, zamiast "lać wodę". NIE MA innego sposobu na zdalną diagnozę uszkodzenia, jak ścisłe wykonywanie pomiarów, o które jesteś proszony.

I po drugie - ten dział nie służy do zadawania pytań o dokumentacje. Jest to jasno ujęte w punkcie 7 zasad działu.

He is wondering if the USB ports (which have been desoldered) should be soldered back onto the logic board to get the picture on the screen (like the USB ports close some circuit when assembled).

Niestety jestem zmuszony zamknąć ten temat ponieważ właścicel urządenia zrezygnował z naprawy. Dziejuję za pomoc i zmarnowany czas.
