Follow these steps to troubleshoot if there is no sound or intermittent sound from the speakers.
IMPORTANT: Not all of these features and/or functions are available on all products. Consult the instruction manual that came supplied with your unit to verify if your particular unit has these features, or if more detailed information is required to perform any of the steps below.
NOTES: Click on the appropriate link below if the issue is occurring with a particular device or connection.
  1. Make sure the MUTE function has not been activated.
  2. Try turning up the volume level.
  3. Check that there are no headphones connected.
  4. Try setting the Audio/Video (A/V) receiver to a different Surround Sound mode.IMPORTANT: Verify that the source you are playing is encoded with Surround Sound audio. If not, the audio will be very difficult to hear using a Surround Sound setting. Set Surround Sound to OFF when playing a source that is not encoded with a Surround Sound signal.
  5. Check each speaker to make sure they are properly connected to the A/V receiver.
  6. Perform a Test Tone function to verify if the speakers are working correctly.
  7. Verify all external audio sources are securely connected to the appropriate inputs on the A/V receiver. NOTE: If the audio is being sent from a television to the A/V receiver, then it may be necessary to disable the internal speakers of the TV or set the audio output of the TV to FIXED or VARIABLE. If the audio output of the TV is set to VARIABLE, then you will need to increase the volume level of the TV.
  8. Make sure the correct audio input is selected on the A/V receiver.
  9. Confirm what type of HDMI® devices are connected to the A/V receiver and then check the following:

    1. Test each one of the HDMI inputs on the A/V receiver to confirm that all of the inputs for the A/V receiver are working.
    2. Try a couple of different HDMI cables to verify there is not a bad set of cables.
    3. Unplug the video source from the A/V receiver and connect the source directly to the television. If there is still a problem with the audio, continue to the next step. If connecting the source to the TV corrects the sound issue, service will be needed on the A/V receiver. NOTE: Additional troubleshooting steps are available to troubleshoot instances when the audio, video, or both goes out when using an HDMI connection.
  10. Verify the DEMO (demonstration) mode is not active.
  11. Change the ATT (attenuate) setting. NOTE: The procedure to change the ATT feature varies by model.
  12. Reset the A/V receiver back to factory specifications.
The troubleshooting steps listed above should resolve your issue. If you have completed all of the steps and the issue is not resolved, service may be required.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

you box is set to a different HD level..meaning your tv maybe 1080i and the box is set to 1080p and your tv won't work on that setting. Find a t.v. that it does work on and reset the box to auto or read the man. to find a reset.. sometimes holding down a certain button while you power it on does the trick.

go into the settings menus and reset it to factory default.Then set it up from sctatch. Of the problem persists you will know that it is a hardware issue in which case a technician can look at it.

Sony BRAVIA... | Answered on Jun 04, 2015


If you can get settings menus up reset the tv to factory default. Should it start working autotune it. Ensure it is set to digital output if it is analog/digital. Also check the aerial/antenna installation is properly connected. If there is some display and sound then I suspect the fault is not too serious.

If it is the type that uses a main light bulb (i.e. ''DLP''), it means the bulb is bad.

If it is an LCD (or Plasma), then it is likely a bad power board.
