#1 PS3 Slim CEH-3004B płyta KTE-001 - brak obrazu przez HDMI

Witam,

problem mam z konsolą jak w temacie, płyta KTE-001. Konsola trafiła do mnie z uszkodzonym gniazdem HDMI. Gniazdo wymieniłem - brak obrazu. Wymieniłem dwa razy układ Panasonic MN8647091, bez efektu. Na pinie 18 gniazda HDMI (+5V power) mam 5V więc poprawnie. Na pinach 15 i 16 (clock i data) mam również 5V ale zauważyłem, że po podłączeniu kabla na pinie 15 spada do 4,8V (nie wiem czy to ma znaczenie). Na liniach danych TMDS nie mam w ogóle żadnego zasilania a wydaje mi się że tam powinno być 3V.

Nie mam schematu do tej płyty, nie wiem do jakiej linii zasilania i przez co są podciągnięte linie zegara i danych na pinach 15 i 16. Czy ktoś bardziej doświadczony w konsolach jest w stanie mi pomóc z tą płytą?

Hello!

Please, post a clear picture of the HDMI part (Panasonic MN chip and HDMI port).

No no, the pahts are fine. I scraped the soldermask to try to trace down the paths. Can you tell me how the Panasonic IC is powered?

First measure the resistances directly on all five diodes, which are highlighted on the following picture.

Resistances or diode mode readings?

Resistances.

Just to be clear: resistances between diodes and ground?

No.
Resistances between both pins of diodes. One test lead to cathode, another one to anode of each diode (the polarity of test leads is not important).

The one marked on the picture have 10k in both ways (polarity). All others have infinity in one way and 116k on the other way.

Hello, do you have some ideas?

Sorry, I missed your post.

Check, if you get video on "AV MULTI OUT" via RCA cable.

Yes, i have a proper image on AV Multi, composite and component as well.

Możesz zamieścić dokładne zdjęcie obszaru ze zdrapaną soldermaską? Dla mnie też to wyglada na uszkodzone ścieżki jak pisze matic. Potwierdza to fakt ze masz obraz na AV out.

#16 Re: PS3 Slim CEH-3004B płyta KTE-001 - brak obrazu przez HDMI

by Slaw • 30 April 2018, 18:29
Ale obrazu na HDMI nie było już przed zdrapaniem soldermaski, zdrapałem ją w drodze diagnostyki, ścieżki są całe.

Have you tried to change the resolution on the console?
If not connect the console via HDMI to the TV, press and hold the power button on console until to the second "beep" (Red standby led -> press and hold the power button -> first "beep" -> hold cca 5 seconds -> second "beep" -> release the power button).

Yes i have, at the very first :)

Check the continuity between listed points (marked on the following picture):
1) Between point A and point A'
2) Between point B and point B'
3) Between point C and point C'
4) Between point D and point D'
5) Between point E and point E'
6) Between point F and point F'
7) Between point G and point G'
8) Between point H and point H'

Image

P.s.: It would be perfect, if you have an old (bad) HDMI cable. If so, cut off one end and measure the continuity between TMDS signal wires and points A', B', C', .... , H'.
