I purchased a sharp aquos tv 2 years ago and have had problems with 'bleeding'colours previously - a technician attended and solved the problem but the problem has re-occurred (blue is running over the screen). I believe that this is a software problem but shouldnt this problem be covered by the consumer guarantee ie the product is not delivering the service intended?. Also the TV continually cuts out which can be remedied only by unplugging everything and re-connecting. If we are not covered under the consumer guarantee what is the action to be taken to solve both problems

I called Cox Communications and the technician told me to disconnect every cable or connection and turn the DVR and T.V. off. Cox ran a diagnostic check to make sure my DVR was reading proper info from their center. It was, and then I reconnected everyhing, cables, HDMI plugs, and finally turned the DVR on. It read Boot, and then, I waited for the time to show. When it did, I turn the T.V. on. It has worked great since then. No problems with sound or picture. Hope this helps someone.

Have you check all inputs as the HDMI inputs and the composit inputs are processed on a different bd?

Your inverter/lamps are bad. Those are only available with the LCD panel as an Assembly, and that is worth more than the TV.

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.

SOURCE: Close captioning on HDMI

The TV will not display closed caption with HDMI input. It must either over-the-air (antenna) or composite input for the TV to manage CC.

To get CC with HDMI from your Comcast DVR, you need to configure the cable box. Instructions can be found here:

If you want CC all of the time, this works well. But since you must power-off the cable box to change the setting, switching CC on and off is a real pain.

Your set-up is similar to mine (Sharp Aquos 46" and Comcast DVR). I have the composite output from the cable box going to a DVD-recorder and on to the TV. Whenever I need CC (usually to catch some mumbled dialog), I just rewind the DVR, and switch the TV input to the composite input. Then I switch back to HDMI to continue watching in HD.
