HDTV picture staticky, cuts out

I have a Sharp Aquos LC-42D64U LCD tv which is connected to an Onkyo TX-SR575 receiver. I have a 50' HDMI cable (hi-quality) connecting the tv to the receiver, which passes the HDMI signal from a Scientific Atlanta HD8300 HD-DVR and Pioneer upconverting DVD player. The HDMI cables used to connect the components to the receiver were EXTREMELY cheap 6' runs. The audio runs through digital coax for both components.

While everything worked great for a couple weeks, I am having a problem with the picture on my tv (the audio still works great, which leads me to believe that the problem is with the HDMI connections somewhere). DVDs now cut in and out to the point where they are impossible to watch; the picture goes to black, and then when it cuts back in (for a few seconds), the TV displays status messages that would seem to indicate a new connection being detected. The cable performs similarly, but with much less outage (problem seems to be far less severe). Both components occasionally display reddish, mostly-horizontal static all over the screen over the picture. Any ideas where the problem is likely to be?

    I have the same problem with my Sharp Aquos 46" LC-C4654U. When watching a movie the picture cuts out with the audio still running then pops back on after 2 seconds.

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.

Digital audio on lc 42sb45u


They are all wrong. I have this TV. What you think is an optical output actually isn't. The only audio output is coaxial and unfortunately it doesn't work with the HDMI inputs. This TV is a headache if your blue ray player only had HDMI.

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..

My problem is when I connect my laptop Sony Vaio (model: VPCEB18FD) at my TV Sharp AQUOS (Model: LC-42D64U) via HDMI cable (v 2.0), I don't have sound...... Thanks!


On the Vaio:
right click volume on system tray and select playback devices
select hdmi/ sdip as default and then in the properties deselect dolby

If you don't have those options you may need new drivers installed on your Vaio. Do you have windows xp? The driver can be found here: support.vaio.sony.co.uk/downloads/info/info.asp?site=voe_en_GB_cons&url=Vaio/Original/AR2_Drivers.zip&ip=RAID_AR21.htm

If you have vista the driver can be found here:
support.vaio.sony.ie/downloads/updates/updates.asp?site=voe_en_IE_cons&c=0&s=VGN-AR&m=2418&os=7&osl=1

On the television make sure you are on the right input. Press menu--setup--hdmi setup--audio select--digital

Hope this helps

Sharp aquos 42"


Check the settings in the TV set for HDMI sound on the input of the TV that you are using. Try another HDMI cable. It may be defective.

It is also possible that there is a compatiblity problem for the HDMI sound between the TV and the computer's sound protocol.

Is it hd ?


HDMI is by far the best solution with this unit. As long as you have the HD package from your carrier and the receiver has HDMI outputs this Aquos will perform well.

Receiver won't put out sound to LCD Sharp aquos


I have the same problem with my Sharp Lcd and Onkyo 804. I believe one problem is that the TV can not accept dolby digital or dts digital audio signals through HDMI. It will play sound if it receives a PCM signal through HDMI. You can try switching the type of signal on the cable box settings and on the dvd player. I switched to PCM and got sound through the TV and the receiver. The problem is that PCM is usually only a 2 channel signal and Dolby 5.1 will sound better through the surround sound theater system. I have not found an absolute solution to this yet, but I am willing to not get sound through the lousy TV speakers in order to get top notch sound through the Onkyo.
