Question about Sharp Aquos LC-46D62U 46 in. LCD HDTV
My Aquos TV was working fine until last evening when the sound on all the analog channels suddenly dissapeared. The over the air channels HD/digital are ok (##.#) but regular ones suddenly became silent! Any ideas?
I've tried all the settings and even reset back to factory and still nothing. Is this something on the TV or did my cable company did something different? It's been working fine for 2 yrs now up till now.
Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

I have the same model TV and the following worked for me. I am using A/V cables attached to Input1 on back of the TV.
On your Sharp TV remote control:
1. Select the Input (1-5) that is attached to your VCR.
2. Go to the menu and select options.
3. Change your color system to NTSC.
This should stop your picture frome flashing on and off.
You still may have a issue with the screen colors. I don't know of a way to address this, other than to make the picture monochrome.
Hope this helps.

I have a Sharp Aquos 46" and go a Comcast HD receiver as well, and had the same problem turning off the Closed Captioning. I order to turn it off you need to go into the box user setting by (starting w/ the cable box and tv on) pressing the power button for the cable box then the menu button for the cable box. This will open up the user settings menu. Just toggle CLOSED CAPTION to DISABLED.

First of all, the change is actually goping from analog over-air broadcasting to a digital signal. Second, if you have cable or satelite, you don't need anything. The only time a converter is required is if you use rabbit ears or an external antenna. In your case, the TV DOES have a digital tuner so you DO NOT need a converter in either case.

SOURCE: no sound on analog channels
Grab your sharp remote and press MENU, arrow over to SETUP, arrow down to RESET and press enter and follow that prompt to reset the unit. Once that is complete turn the tv off and unplug ONLY the tv for one minute then plug it back in. Then turn the tv on and see if you have channels, if you do, your audio should work on you analog stations, if you have no channels and all you see is a snowy picture do the following press MENU, arrow over to SETUP...arrow down to CH SETUP and press ENTER...you will then be at a screen that says AIR/CABLE, press ENTER, select CABLE or CABLE(STD) if that option is available to you. after then, arrow down to CH SEARCH, press ENTER, then you should be highlighted on ANALOG AND DIGITAL SEARCH...press ENTER and wait for 15-30 minutes ( or until you get a picture back) and make sure you DO NOT press any buttons or turn the tv off and you should be good. good luck 2 u
