Most common questions used to investigate
Are the speakers producing any sound?
Is there any power outage or fluctuation in your area?
Is your home theater system plugged into the power socket properly?
Check your main circuit board. Is their any switch that has been tripped?
Is the power button placed on the home theater system's main console not responding?
Check all the connections of the speakers with the main console. Are they properly fixed on both ends?
Have you configured the home theater system from the internal software settings?
Are the surround speakers not working?
Is the volume set to a high level?
Check the connections of the surround speakers from both sides. Are the connections properly fixed?
Does your console support surround speakers?
Are the speakers emitting noise with the normal sound?
Have the settings of the speakers been done properly?
Is there an annoying humming sound with variable volume coming out of the speakers?
Common conclusions
Due to the power outage your home theater system may not be working properly. Contact your local utility supplier and inform them about the power outage and file a complaint.
This should be the cause for your malfunctioning home theater system. Plug it in properly.
The flipped switch should be the cause for the home theater system to not work. First flip the switch and restart the home theater system.
The problem may be a fault push button. Contact a professional or request a service from the original manufacturer.
First reconnect the wires properly as the incorrectly connected wires may be the cause for the malfunction.
Configure the settings from the main menu of the console as without the configuration the system cannot function.
Contact a professional to diagnose any further problem as the most likely cause for the fault may be the internal circuit of the console.
Turn up the volume as in some cases, the sound in a particular scene of a movie can be very subtle, and your initial impression of there being a lack of surround sound might be because it’s playing too quietly.
Connect the speakers with the main console properly before trying again as the problem may be with a wire that is not connected properly.
You may have to replace your console as some consoles do not have the surround sound feature.
Contact a professional to diagnose any further problem as the most likely cause for the fault may be the with the speakers themselves.
First configure all the speakers from the console's menu as without the configuration the speakers work as individuals and are programmed for standard output instead of working as a home theater system.
The problem may be with a wire that has been teared and it is exposed to the outside. You should tape the exposed area or change the wire itself
Contact a professional as the problem may be with two conflicting pieces of equipment which might be faulty.
For any further problems contact the original manufacturer or a professional.
