Sound Delay between TV and Surround sound

I just had myNS-LS55X-10A delivered.  It replaced a 7 year old 52" Hitachi that was working fine.  I had just replaced my surround sound receiver with a new Yamaha unit a few weeks ago.  As soon as they hooked up the new 55" there was a significant sound delay between the TV and the surround sound.  This was not a problem with the old Hitachi.  I've searched these forums and tried disabling the DCM(?) and that didn't help any thing.  What is the fix for this?

Re: Sound Delay between TV and Surround sound

Hello twotoejoe,

Welcome to Community@Inisgnia™!

First of all, it will depend on the kind of connections you are using, and where you are getting your signal from (cable box, DVD player, etc). Remember that if HDMI is a coded signal, to decode it will take time, hence the delay. A good first step is to change the DCM settings (that forces the TV to work at 120 Hz, and can be a cause of delay), and try to set the TV on Game Mode. Also, you can set your connections so as to have the TV SPDIF output to the receiver, instead of having a direct connection from the source, so that if any delay, it will be also sent to the receiver and you will sync them. Lastly some receivers will have a lip sync option to compensate this HDMI delay.

 


Thank you,

Re: Sound Delay between TV and Surround sound

OK, when the tv was first installed, it was on regular audio cables.  Had delay problem.  I obtained HDMI cables and changed them out, still delay problem.  I've also tried getting the signal straight from the cable box or through the receiver, no change, still the delay.

 

Please elaborate on the 'DCM' changes and other changes you mentioned.  

 

Thanks,

Re: Sound Delay between TV and ANY sound

My TV's (NS-L46X-10A) audio almost always happens before the video signal - sometimes a full second or more before the video comes up.  This is with audio from HDMI4 (PC/Netflix), AV2 (Composite PS/2 DVDs), and AV1 (Composite Wii).  Sometimes it happens through cable-in HD/digital signals too.  And it is *always* annoying.

 

To answer your first question, click Menu > Picture > Advanced Video > scroll down to DCM, and change it to OFF.  I tried it on "Low" and that didn't help.

 

I can't find *any* "Game Mode" on this TV.

 

Even after doing this, the timing is off.  On the Wii we have to calibrate lag to be able to play any guitar hero game, but that does seem to work after that in-game delay.  Netflix on HDMI from a PC is at times very, very bad.

 

Additionally, the audio signal levels are off by a LOT.  AV2 is way, way low - I turn the TV's audio up to 63 and it is very hard to hear the TV when a group is around.  But with AV1 I have to turn the audio down to 10 or 15 while the cable signal is pretty good around 30.  If I put audo through a receiver and video to the TV, the audio is early by about a half-second.

 

Any solutions to this horrible audio?  Or is this a problem in my TV?

Re: Sound Delay between TV and ANY sound

"Game Mode" is a button at the bottom of the remote, 2nd from right, top row in the group of 8 buttons at the bottom of the Insignia remote control.

 

I forgot about it because I immediately clicked it - so all of my delays were happening while Game Mode was on.

Thanks for the response, but I tried changing the DCM to all settings and it made no difference.  Same with the Game button, on or off it makes not difference.  I've still got the **bleep** delay!

BTW. I don't do any gaming at all, so I don't EVEN know what problems I would have if I tried hooking up a Wii or a PS3!

Re: Sound Delay between TV and ANY sound

most A/V recievers have a delay you can set so that it syncs up the audio . Look at the instructions of your A/V reciever and there will most likely have an Audio Sync adjust so that the audio is sync'd up with video. i had to do this with my Sony A/V reciever for when i watch Blu Rays

Re: Sound Delay between TV and ANY sound

The only 'adjustment' I could find was an adjustment in the distance the speakers were from the TV.

Re: Sound Delay between TV and ANY sound

That was the only adjustment my receiver had as well.  I solved the issue by hooking the optical cable from the TV to the receiver (as I believed was mentioned earlier).  Unlike most TV's I have worked with, my Insignia will pass DD 5.1 through to the receiver if the source device provides it via HDMI.  I only use this hookup for my digital cable, where DCM enhances sports and some documentary/reality type shows (most of which are produced and/or narrated by Thom Beers).

 

As long as I have DCM disabled, I don't experience any delay with movies.  I have a DVD player hooked up via component for my kid's DVD's with a coaxial digital cable going directly to my receiver.  I have a Sony BDP-S550 Blu-ray player hooked up via HDMI to my TV and 5.1 analog to my receiver. 

 

DCM seems to make most movies look like the horrible pan and scan version of Ghost Busters played on standard def cable channels anyway.
