    lg 46LD550 HDMI no sound

    I got in a LG with no signal on HDMI ports so I replaced the HDMI IC and now I have picture but no sound on just the HDMI the other inputs are working fine for sound. Any ideas? Would the amplifier ic have anything to do with just HDMI?

      maybe try a simple reset, unplug tv for a minute, hold power button in for 30 seconds, plug tv back in and try it, no joy, recheck your work, try a factory reset, try firmware update/reapply, may have received a bad chip.

          Tried that first then also took all firmware updates. Still no joy.

              puzzler, thinking the new chip could be bad.

                              Would a bad chip cause no sound.

                                  it turns out I needed the technician remote to go in and reset the HDMI settings. I have sound now.

                                      seems odd that the factory reset didnt reset the hdmi.

                                          Mackie CR4 amplifier no sound
                                          by UserXP
                                          Hi, people.

                                          I've got an amplifier assembly from Mackie CR4 parts. It's just an amplifier, there was no speaker housing, so I used my set of CR4s to test it.

                                          Anyway, upon connecting everything and hooking the "new" amplifier to an audio source, the sound played clearly and strongly for the first ten seconds. I was happy it was working. Then the sound started to fade out during the playback until it was no more. After it had "dropped to zero", there were two very short intervals of sound playing at the normal volume, as if the amplifier was trying to...

                                          Onkyo HT-R390 no sound output, video output ok
                                          by FrancescoV
                                          Good morning everyone,
                                          I'm trying to repair an onkyo ht-r390 that has no sound output, despite the volume being at maximum, the rest seems to work; the video output signal (coming from an hdmi input) is present, but the audio is absent. Similar situation if I send an audio signal from any input I have no output.

                                          The firmware reported is the following:
                                          M:1.00/11107BLP
                                          D:?.??/????????
                                          O:1.00/11107AL

                                          The DSP firmware given the question marks seems corrupt.

                                          On the BCHDM-0678 - 25140678 - QPWBCHDM0678A0 board the chip that usually seems...

                                          Not all TVs can handle surround sound on a HDMI input

                                          With a home theatre PC connected to a TV via HDMI, Windows reveals that the TV only supports stereo sound even though the TV has a HDMI ARC connection to an AV receiver which is powered on; I also had an issue that the AV receiver does not always retain the input setting for routing the HTPC video through to the TV in standby.
                                          So I connected a second HDMI cable to the HTPC and set it to duplicate the video outputs, but I had random audio dropouts when playing content with surround sound being passed to the AV receiver (dropouts did not occur when I replayed the content where it dropped...

                                          Dear Electronics Experts:

                                          I have the following problem I am trying to troubleshoot. Unfortunately, I have contacted Anthem themselves and even a local distributer but I am not having much luck. Also, I have scoured the internet and unable to obtain a service manual. The Anthem service rep has also replied that he is unable to provide me with any service documentation. I have performed numerous searches on the internet and cross-referenced a few other AV receiver makers (Denon, Marantz, Onkyo) and found certain similarities to block diagram...

                                          I'n trying to fix a M&S SYSTEM DMC-1which have following problem:
                                          I'm using FM station to do this fix, I works perfect if volume below around 8 or if bass is set to zero, the sound can go to 20 without problem, but if I set bass to maximum and try to go over 10 the sound comes distorted ... I saw a video on YouTube the person saying about the main capacitors on the power portion, but I disconnect the main transformer and inject direct to the capacitors PINs my bench power supply -23v 0v +23v, but still distorted so I think the problem is not the capacitor neither the transformer...
