Insignia TV no audio on non HD channels via HDMI cable.

You will need to used a red and white cable that will connect to the (audio out) on the comcast box and then to your (in audio) on your tv.

Thanks

you will need red and white ended lead conected between tv and hd box
audio out on hd box and audio in on tv

I removed the HDMI cable and connected with component video and rca audio. No more white screen.

Picture quality looks good. I don't know if it's as good as HDMI, but then I don't need to reboot the TV three times to get to teh on-demand menu... Grrrrr....

I am trying to contact Toshiba on this as well. I have seen several reports of this problem on the web.

In a nutshell, there is no solution to this problem. The new Insignia TVs have a compatibilty issue with certain HDMI connections. The best thing is to return the TV and purchase another brand. I bought the LG w/built-in DVD and everything works great.

did you remember to put audio leads in

This looks similar.

if you have a cable box then it is probably the resolution settings in the cable box, what type of cable box do you have

I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.

I have one in my shop with the same problem. Power is the only function that works. I repaired the power supply six monts ago. Now it looks like a bad digital processor board which is non-repairable. I can't believe what's happened to the tv business. Absolutely disgusting!
