    Denon X5200W - No Video, No Audio and CAN NOT SET UP

    Hi Guys,
    I am trying to fix a Denon X5200 AVR with the following symptoms. Appreciate if you can help my by providing pointers to fix this.

    No Video output on the TV/Monitor
    No Audio on speakers and also in headphones, though I can hear the speaker relay clicks upon power up.
    Set up Function ( both on AVR and remote) doesn't respond. so can not do the configuration.

    Thanks,

    Greetings.

    Well, you can start with the standard things, but most likely the problem is in one ( or more ) of the chips on the HDMI board.
    The standard thing is to measure the low voltage rails. Then check if each chip/controller on the hdmi board gets its power supply.
    If you get good voltage readings everywhere, you can try tracing the audio signals through the board.

    If there are any BGA chips on the hdmi board you can try reflowing them.

      You are saying that faults on the HDMI board can disable the menu system? The OP does not say which input he is using as a source. Need more specific info on that part.

      What does it mean if you have a "normal" display on the front panel, but no response to front panel buttons or to remote control?? I would say that the unit is in "child lock" mode. Just a guess.
      Is it plugged in?

        I have two personal examples - denon 2113 and onkyo tx nr609
        Both have "no video and no sound" issue.
        Onkyo have acknowledged the problem and blame faulty BGA chips.
        Denon officially have not acknowledged the issue, but many users have experienced it ( there is a topic about this here ).
        Both units appear to be fully functional - they switch on, the displays work fine, the menus are fine, only that they do not pass any sound from the inputs to the analog part ( the amplifiers ).
        The denon unit indeed has partial menu functionality - for instance it operates fine the network part ( successfully opens network radio streams and the network/usb DAC produces sound, but that sound then is not routed properly to the amplifier ), but cannot operate the tuner section, the output switching chip ( even though the display shows switching through the inputs ) and most likely the main DAC, the DSP processor, the HDMI switching and so on. The firmware version of the HDMI section also seem to be corrupted.
        People say that the denon problem is caused be deteriorating memory chips - the write/read processes are interrupted and eventually the firmware gets corrupted/unreadable which causes partial or total failure to operate.

        Of course this does not mean that the post owner's unit has the same problem. It is always best just to start with the simple things - factory reset, voltage readings, loose connection, etc.

          You are saying that these two products are actually the same, or very nearly so? Just a different brand name on the front?
          Is it plugged in?

            Oh no, not the same.. they /that two units/ just share similar issue - premature chip deteriorating and/or bad BGA solder joints.
            Well, at least the board designs are different, the analog parts also. Still, they use third party cpu, memory, dps, video processing, hdmi/audio switching, dac/adc chips and it is not uncommon to see the same chips in one generation similar price range receivers..... so probably yes.. it could be said that the hardware inside the metal boxes is the same.

              Help troubleshooting an audio problem with an RCA SGT-250 CED Player
              by samson7point1@yahoo.com
              The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.

              The player processes the audio signal using two different reference frequencies. The "R"...

              Schematic for Denon Remote Control RC1156
              by hemant_2222
              Hello Everyone,

              Hope everyone is enjoying their repairs at hand!.

              I am looking forward to get the schematic of Denon remote control RC1156. Actually long time no use of the remote leaked the battery thereby corroding few parts as well as the tracks.

              I was able to join few of them but the remote is still not working, so i am looking forward for your help, in case anyone understand the schematic or the remote circuit diagram and could me assist me in repairing it.

              Please refer to the attached picture, i think the voltage divider is missing...

              Mi TV 4 Pro-Samsung Panel LSC550FN20 - Video problem, backlight and Audio works fine.
              by SolarFlare
              Hi,

              My barely 3 year old TV has stopped displaying video, although the video output comes for a few seconds after turning ON which displays the manufacturers logo then shows the home screen (all this with some blue flicker) then the video goes blank and the screen is dark blue with the backlight on. The audio output works perfectly and the TV also takes in voice commands(smart TV).

              The TCON board has the following Chips -
              Samsung VTU63A0
              RT6939 - 2nos.

              and all these chips are getting real hot within a minute, I dont know if this is normal....

              I have problem with probook 650 g2 - laptop shows connected headphones Even without them. If i pług headphone Jack - computer show disconnected headphones. Speakers work when i change sound output.
              I replaced Jack board - nothing changed. Computer shows connected headphones even without Jack board connected to motherboard.
