    PS4 WLOD repair - need help.

    Hello!

    I have a ps4 for a repair. I have replaced HDMI IC, HDMI port is ok and have replaced it before and it was working fine for about year after the repair.
    And now again WLOD have appeared. I have tried to replace HDMI IC but it did nothing.

    I have attached picture with my measurements. Can someone help me to solve the problem?

    Thank you!

    Diodes seems ok when are desoldered.

    I have checked filters too and filters are ok.

    D4 is OK.

      That HDMI port is very crooked.

      Are you sure you don't have adjacent pint touching each other? I would remove and re-solder the HDMI port. This is a difficult repair, and I do not think you installed the HDMI port correctly.

          Well, your first issue is that the HDMI port needs to be replaced.

          The black backer plate of the port has been pushed back. The right most three pins are pushed in.

          The pins should look nice and in alignment with enough solder to wet the pad without globbing or shorting to the adjacent pins. (see my picture below)

          When you installed the connector, are the pins sitting flat against the board?

              Would you mind posting a higher resolution photo of your board? Lets work through this.

                  Re: PS4 WLOD repair (no picture) - need help.

                  hdmi port look pushed in . if that happens it will never work no matter how everything is soldered. The hdmi encoders dont really fail on those models like that. ive seen people try to replace the hdmi ports and leave solder bridges across the pins , dropped port to clear shorts put port back in perfect ps4 came right up. No encoder change needed.

                      Yeah definetely the HDMI port is pushed in - the black plastic at the back of it should be flush with the metal frame, not bulging out. You have to replace the HDMI connector for sure - then see what it does

                      Be careful to order the correct HDMI connectors - I got some from Ali-express that were upside-down. Once i fitted the correct type (another cycle of desoldering and resoldering) all was fine

                          Hello. I need some help with this topic if anyone can give me a hand. So I had a few PS4 already with WLOD, some I could fix(bad HDMI port, bad filters, and some bad HDMI encoders) but whenever o have a bad MN864729 HDMI encoder I'm always struggling. Don't know what I'm doing bad. Not sure if my solder skills just it's not good or if it's something else. Now I have this ps4 fat 1200 series(sac-001) with a wlod. I have checked the port and it's perfect, filters all good, diodes and all SMD components around HDMI encoder and port all seems to be normal. Just missing the encoder itself I already...

                          PS4 fat has inconsistent signal after HDMI replacement
                          by supravit2000
                          Hi, guys!

                          I am not a professional, all I can do is solder stuff on the boards, so I would really appreciate it if someone with knowledge shares his experience/thoughts on a problem I have with a PS4 console.

                          My friend gave me an original fat PS4, board model SAB-001, with WLOD, that has been previously opened. I changed the HDMI port, couple of pads on the board were ripped, which I connected to the corresponding caps/resistors? Just did so as in a shown diagram (one of the ground pads I ripped off and left it not connected). However, there was still no signal, so...

                          PS5 WLOD EDM-030

                          Hello guys,
                          I try to repair a PS5 with a WLOD.

                          At the beginning I should tell that I get a BLOD and after the UART reading and shorts on the caps near by the HDMI Encorder I change the IC. And after the change I get a WLOD. I also noticed that the filters was blown. I change them also.

                          The caps near by the HDMI Encorder are not shorted now. I also change the HDMI Port.

                          I get some readings in Diode Mode which doesnt look right to me.

                          1. HDMI Pin 18 i get 0.100V and Pin 19 OL
                          2. Diode on the back side 0,100V...

                          Certain DisplayPort-HDMI cables can disable HDMI CEC communication

                          With a setup including a TV and AV receiver where HDMI Consumer Electronics Control (CEC) and Audio Return Channel (ARC) functions were working, these two functions stopped working after changing some connections (not the one between the AV receiver and TV), so I believed it was a corrupt setting in the AV receiver or TV, but when I disconnected a passive DisplayPort-HDMI cable (which a Multimode DisplayPort connector supports HDMI with a low cost passive cable or adaptor) connected to a home theatre PC, HDMI CEC and ARC functionality was restored.

                          LG LCD TV HDMI PORT FAULTY
                          by RossMoodley1967
                          LG LCD TV picture comes on intermittenly using hdmi port.The sound is on permantly.The hdmi ports looks fine and soldered in securely.The 3.4v coming to the main board is not present(not sure if will affect the hdmi port or where that voltage goes.)The hdmi cable is fine because it works on another tv.The ceramic caps connected to the hdmi controller ic is reading 39 ohms.Could the hdmi controller ic be faulty(feels very warm to touch).The RCA jacks work normally .Thank you in advance for your assistance..
