17 Frustrating Home Theater Problems To Solve In No Time


There are always very tiny problems in home theaters that we usually miss out on.

 These tiny problems may soon transition into big issues because we don’t know what is causing them.

Like I  bought a micro HDMI cable and tried to plugin into my home theater TV. I tried a lot but I was unable to the plugin. I applied all my force to insert it into the port and soon I was frustrated and left it there but when I closely examined the port and the cable.  I realized that the cable and Port are different.  I ran to the market and later on, I learned that there are many types of HDMI cables.  you cannot simply go and pick any HDMI cable and hope that it will work.  My home theater is supporting type A HDMI connectors and I was forcing it to accept the micro HDMI cable.

Due to a lack of my experience, this new problem was created.

 I will share common frustrating home theater problems in this post with you.  So when you try to set up your theater system you don’t face these problems and can enjoy your movie immediately after the setup.

I have categorized these problems and also have designed an infographic for you so you can better understand these problems and eliminate them from your system.

Video Problems

TV Picture Quality Is Not Satisfying

Sometimes when we turn on the TV  we experience the top quality of the picture but after a few minutes, we experience poor picture quality.

If this is the case with your tv.  Go on and unplug the power cable from the electric source.  Keep the TV off for a minute and then plug back the power cable to the electric source again. 

If the issue is not resolved, try to replace the power cable.

If the problem is still there try to change the display source; like if you are having Amazon fire TV connected. Now connect the gaming console and check the display quality. If the issue is resolved then well and good.

If the problem is not solved then try to connect your TV with the receiver through an HDMI cable if there was a digital cable connection before.  Is there still a problem? try to upgrade HDMI cable technology, replace simple HDMI with HDMI 2.0 technology or beyond if available.

If the problem is still not resolved then your TV might be faulty.  It is time for you to buy another TV.  Read our simple buying guide for the TVOpens in a new tab. here or just download the checklist at the end of the article.

The Picture Of The TV Looks Greenish Or Red

Sometimes you might experience seeing red or green faces of the movie characters on your TV or the overall picture might be green or red. 

 This problem mainly occurs due to the tint’s wrong calibration.

You may have set it very low or very high.  You can easily erase this problem by just tweaking the tint unless you see a clear difference.

 The other cause of this problem might be that you have set up warm colors in your TV setting rather than cool and normal.  change the setting to cool and see if the problem is solved.  This second step will surely solve this problem.

Projector Picture Quality Is Not Satisfying

There are three common problems your project will be facing if it is projecting poor quality of the image.

  1. First, see if the resolution of your projector and the resolution setting of your home theater receiver are matching.  For example, if your home theatre receiver is capable of 1080 pixels or of 4K resolution and the projector has a capability of just 720 pixels.  Then you will definitely get a poor image quality out of the projector.
  2. Another reason may be the connection of your projector with the home theater receiver.  Check if the HDMI cable is connected properly and make sure it is not left unplug or loosely plugged.
  3.  The third problem might be with the wrong setting of the projector, the setting of image resolution, contrast, or zoom.

 Don’t worry these problems can be fixed easily.

  1. Set the receiver and projector resolution setting in a way that they can match each other.  In this way, you will have the best picture quality.
  2. Check if the cable is in a good condition. Cables in a bad condition might be the cause.  you should always use only good quality HDMI cables.
  3. Go to the image setting and adjust those.  Tweak the image settings and examine the picture quality. Slight changes in the image setting will drastically affect the image quality. Try to check the manual that comes with the projector for this task.

If the problem is still there, There might be a problem with your projector lens or projection bulb.

You can replace these parts but we recommend that you should buy a new projector.  you can download and read our projector buying guideOpens in a new tab. checklist where we discuss that you should only choose 4K image quality projectors and those which are having long-lasting lens life and higher lumens.

Unusual Dots On The Projector Screen

You might experience annoying dots on the projector screen. These dots will be green or purple. Go and check the lens and green panel of your projector. There will be dust particles on the green panel. You should regularly clean the green panel to successfully avoid this problem.

Sometimes The Sound Is Audible & The Video Is Not Visible

There are two possible causes for this problem.

You might have missed plugging the HDMI cable into the receiver. This possible cause does not seem to be a big issue but at the front, the home theater looks cool and nice and at the back of it there will be a forest of cables.

Go ahead and check the HDMI cable if they are plugged properly.

The second possible cause of this problem might be that you have plugged the TV HDMI cable into the wrong port. If you have made this mistake then you may hear the sound and the video will not be visible or opposite of it. 

Change the HDMI cable input port several times until you see that the issue is resolved. 

Audio/Video Are Not Synchronized

This is a very frustrating problem. You hear dialogues even before the actor opens their mouth and vice versa.

 This is because you don’t have a powerful receiver that can handle your pro-level of setup.

 This is a very common problem that manufacturers are now including its solution into the system.

 Go to the setting of the receiver and open the audio delay option.  tweak this Option for a millisecond and check if you see the difference. Tweak until you see a clear synchronization between the audio and video.

Audio Problems

Home Theater Audio Problems

Your Surround Sound System Audio Is Of Poor Quality Or Not Hearing Anything

Go ahead and check that whether your audio source or your receiver is able to output 5.1 surround sound or 7.1.  If your receiver or audio sources like songs or movies are not capable of this technology then you will get poor quality surround sound audio.

Many audio sources are created for 2.1.  To resolve this issue you must convert this 2.1 to 5.1 or greater surround sound. You can do this in the settings of your receiver.

The second problem might be that you have not plugged cables properly into the receiver.  check those cables properly.

Multi-channel bitstream should be selected if you are using a Blu-ray player.

This one might seem funny to you but sometimes we forget that we have muted the audio of the system by mistake or by intention and we have forgotten this time when turning on the system.  you must check if this is not the case.  Unmute the audio, throw your remote, or turn up the volume.

Always choose speakers from same brand or better be from the same series. Here I have a review on best speakers under $500Opens in a new tab..

Sony theater System troubleshooting (Can Be Replicated For Others)

Front Speakers Sound Is Not Perfect

93% of the time this issue is caused by improper setting of the speakers in the receiver settings.

 The front speakers and main channels are usually created to give a nice experience of clear dialogues and the subwoofers are designed for the base.

Head over to the receiver settings and choose your front speakers and other speakers to “small”  in this way the receiver will push base to the subwoofers and you will hear clear sound from the front speakers.

Height Speakers Are Not Giving Me The Sound That I Desire

The angle of the speakers plays a very important role in the overall experience of the sound.

Try to change its angles and see which angle is giving the best sound.  you should read the manual of the speakers for this reference.  they might have some tips for you to apply.

Another solution can be to tweak the Codec settings of the receiver. Check which codec setting is the best suitable for it. 

Height speakers are very critical for Dolby Atmos, read my this review to know about the best Home theater in-ceilling speakersOpens in a new tab., few out of them are incridibles for Doby Atmos.

Bass Problem

There are at least 4 causes of this problem.

There are base dead areas almost in every home theater room.

 If you have placed a subwoofer somewhere in your room. Roam around the room and continuously observe where you experience this dead base in the room. If you experience these dead base areas.  You have to install another subwoofer there. This will fill that dead area and you will experience more base out of your subwoofers.

Again the position of your subwoofers matters a lot.  The best area for the subwoofers will be at the front corners a little near to the wall and the face of the subwoofers should be towards you.  if you are not getting the desired base. Try to place it between the front speakers and near the wall. 

Don’t forget to set all other speakers in the received setting to “small”.

 If the problem is still there,  I will recommend buying subwoofers that are compatible with HDMI cables.  Don’t use RCA cables for this type of connection anymore. RCA cable is a thing of the past now.

My Speakers Sounds So Shrill Or Having An Echo In My Room

Sometimes we buy new speakers and install them.  we experience shrill sounds from the speakers.

The speakers sound shrill because there is no material in the room to absorb some amount of this sound.  so they should erase the piercing effect of this sound.

 This sound-absorbing material can be a couch or a soft rug or any other thing of this type of material.

One simple solution that can work for both of these problems of echo and shrill sound is installing acoustic panels.

 you have to install the panels on the walls of your home theater.   These acoustic panels have the ability to absorb sound.

By absorbing the sound eliminates the piercing effect of the sound and also prevents the reverberation of the sound. in this way, you will not experience any echo in your home theater room.

To eliminate as many errors that you can in the audio of your system. You should go for the complete set by the manufacturer. Read my this review about the best theater systems under $1000Opens in a new tab.

Experiencing Static From My Speaker

This problem can occur due to damaged speaker wire or loosely plugged wire in the receiver.

 check if this is the case and plugged the wire properly.

 try to run speaker wires in places where they will not get damaged.

 take care of the speaker wires then you will least likely to experience this problem.

Another cause of this problem might be that your speaker is damaged.  In this case, you have to replace the speaker with brand new.

Receiving Head Aching Humming Sound From Speakers

This problem may be caused due to the interference of two speakers’ electric fields or frequencies.

The first step you can take is to tweak the volume of the speakers and check if the humming sound is disappearing or not.

 If the issue is still there,  the next thing you can do is to talk to your receiver company customer care.  Hopefully, they will show you at which distance to install the speaker from each other to dismiss this interference.  This will disappear the humming sound.

The Whole System Is Not Outputting The Sound

This one problem is the most frustrating of them all.  you have set the subwoofer the speakers in the way we have taught you in this guide. You have considered installing acoustic panels and sound-absorbing soft materials in your home theatre but still, there is no sound.

This is because you have done the wrong connection of speakers with the receiver.

Check the back of the receiver and you will notice red and white jacks.  These are positive and negative connections Jacks for speakers. 

 Make sure that you have connected positive to positive and negative to negative. 

Hopefully, after this work, the problem will vanish.

Receiver Problems

Home Theatre Not Turning On Or Receiver Is Turning Off Frequently

 There are three possible causes of this problem.

Speakers connected to the receiver are consuming more power than the power capability of the receiver.

 check if the receiver is capable of powering your speakers.

 Another possible cause of this problem might be that any two wires of connection with the receiver are in contact with each other.  they will short the receiver.  check at the back of the receiver and back of the TV and speakers and make sure that no two wires are in contact with each other.

Another possible cause may be that your receiver is now damaged and you should replace it with the new one.

Home Theatre Is Not Delivering The Signals

This might be because of faulty media sources like fire TV or gaming console or Apple TV.

 Another possible cause of this problem will be that you have done an incorrect connection to HDMI cables.

Other General Problems


My Receiver Is Not Getting Universal Remote Signals

 A universal remote is an amazing gadget. It makes our interaction with the receiver easier. 

But sometimes it doesn’t work then you should first check if the batteries in the remote are not working or fitted incorrectly.

Try to check if there is anything between your remote and the receiver.

Don’t place the receiver in a cabinet-like structure.  It is good for receiving the remote signal and also for ventilation.  ventilation is very necessary to prevent overheating of the receiver. 

 If this is not the cause.

Then check the frequency type of your remote and your receiver.  if your remote is having infrared frequency then you make sure that your receiver frequency is also infrared otherwise they will miss match and the wireless connection of remote and receiver will not work.  if you are having a radio frequency remote and your receiver is capable of infrared frequency.

Then the connection can be corrected from the setting of the receiver by changing its frequency to the radio.

If your receiver is not providing this facility then you can even buy a gadget that can convert the infrared frequency to radiofrequency.
