HDMI audio problems with my sharp LC42D64U

When I hook up my Sharp LC42D64U with an HDMI cable the audio cuts in and out. I tried that HDMI cable on another tv and there is nothing wrong with the cable. The compoment cables work fine with the Sharp LC42D64U

    I am having the same problem with the audio cutting out when using HDMI cable connection to a cable box. Does using the component cable connection solve this audio problem with the Sharp LC42D64U ?

    I'm having the same problem on my Sharp...sound cutting out. It's mostly no sound and then a little short sound occasionally. We've had the Sharp since Oct. 2007 and it's been fine up until now. I run a HDMI cable, which my cable company - Cox - doesn't support. I'll try the component cables and see if that's any better.

    What source are you using? Cable box? Dvd player? Model and brand of source?

    I have found out that the Bose System that I have connected to the tv, game consol. Now when I disconnected the Bose System the controller worked 75 percent better, when Black Ops l l is played, the controller left and right, still has a sway to it, enough to get a bad kills vs be killed, Maybe I will half to let the 80" Sharp go and find another big screen tv the works with Bose 5.5 Surround sound. I don\'t kno ??

  • theDOG_FATHER48 Mar 06, 2013

    That is 5.1 Surround Sound.

I had the same issue with my Samsung. The sound would drop with the HDMI connection from time to time, sometimes two or three times per hour. I checked on Samsung's website and they had a firware update for this particular issue (I guess that I had sent me too many emails regarding this problem and they finally put an update for it.) I updated the firmware last night and TV was running for a few hours without any problems. Check on the manufacture's website of your TV and you might find a solution for it.

Using the component cable connection solves the HDMI cable audio problem with the Sharp LC42D64U.

Thank you for your help

The problem is that your cable box is putting out too low of a bandwidth to your tv and is cutting out completely. Since its all digital either its there or not. try switching to componant cables. Cable boxes only support up to 720p anyway so you wont sacrafice any quality.

Hope this helps

What's your problem?I just purchased a I just purchased a Sharp LC32SV40U. I'm trying to hook it up with my Shaw Direct DSR 505 receiver (DVI to HDMI. I cannot find how to get sound using this


When using this type of adapter you only feed video into the TV/monitor
you have to use a separate set of RCA audio wires to feed the audio into your tv.

Sharp Aquos LC42d64u has blurry picture...


Hi,

Is it slow and blurry? if yes then return it to warranty immediately. The video processing circuits are malfunctioning and the repair cost is prohibitive if you must pay for it on your own.

I hope it is still under warranty. So, do not delay getting it into the Sharp Authorized facility or back to the retailer you purchased it from.


The connection cable you use could have something to do with it, but is should work on all formats. The best for reliability and absence of blocking is just analog composite - but that is also the lowest picture resolution. S-video is okey too, but it is analog as well. Component is the highest grade; going to hdmi is just another way of receiving the signal - I don't think it will effect the error correction problem in any way. My opinion.

Goodluck..

Sharp Aquos 46" HDMI problem


I have a similar problem. The Sharp TV aquos appears to be shutting down my blue ray player and dvd recorder when connected via HDMI. They work fine and never close down when I connect them via the rca cables either single video connection or a composite 3 cable rca lead. I have 3 HDMI inputs on the tv and the problem occurs on all 3. Any suggestions?

I HAVE A LCD SHARP TV MODEL LC42D64U SERIAL NUMBER 806815957


try a software upgrade available at sharpusa.com find your model and download the software to a USB thumb drive then insert it into the USB port on the side of the set. enter into the menu go to "digital" select software upgrade and follow the promts. do not unplug or shut off the set until the upgrade is complete. if it doesn't recognize the software on your thumb drive try formating the thumb drive to FAT and not FAT32 reload the software and try again.

Mono sound only


I have an LC42D64U with firmware U0709111. This is an 11 month old unit. It was working fine until I lost power one day, then I couldn't get any sound. It always showed up as Audio: mono. I tried every setting and nothing (although XBOX via HDMI still played though the onboard audio, so I knew it wasn't a HW issue).

After searching around for a method to change the mono/stereo I resorted to the Fred Flintstone's fix and simply pulled the plug on it. Immediately after turning it back on it worked.

This is hardly a fix but it worked for me.

Connection problem


The best hook up for this unit is to use the hdmi if your samsung box offers hdmi output. The panasonic vcr should be hooked to any one of the composit video inputs with the yellow video cable and the red and white audio cables. If the vcr does not have composite output then use a rf (coax cable) to antenna a input and put the tv on channel 3 or 4 as vcr is set for.

HDTV picture staticky, cuts out


I suggest contacting Sharp directly. I just did and received absolutely nothing from them. But if others such as myself who have the exact same problem as you ( I own a LC32D40U just over 2 yrs old) contact then maybe something can get done.

I will certainly NEVER recommend a Sharp product to anyone and will as of this moment respond to every message out there letting everyone know exactly how bad Sharp's product are. I would recommend the Sony XBR series to anyone looking for an LCD television.
