Sound keeps cutting out

SOURCE: Set up

Seems that Hitachi DESIGNED the sound to cut off from the Audio Out jacks if you use component video or HDMI inputs. Has to do with copyright laws of the HD Video -- which makes it asinine that they disabled the audio as well, as it's not part of the copyright issue. Seems to me they were just lazy to disable the ENTIRE set of output jacks.

I am hoping to find some sort of hack for this (either firmware or severing/splicing a control wire). However, I can't find much information on this yet.

Hi, without a manual to hand, i don't know, but my Panasonic had the same problem, but I found somewhere in the settings, I could change it, it has something to do with AV and Digital TV and hdmi setup, give it a check.

I hope this helps to some degree, but give us a shout if you require more help.

Go Setup in the menu. At the bottom you will see Reset The Software when power is turned off. Switch this to No.

if will tell you how to trouble shoot this tv. these tv's are known for two caps in the power supply to go bad and they need replaced then you have to test the sdr boards if they are bad you need replacement boards or you can send them off to be repaired. the link for the repair guy is on the page. this guy also sells the repair on ebay but if you contact him directly i beleave the price is lower. just tell him you were send over by home theater shack.

I know it Sounds silly I also have a Hitachi TV and got issues with HDMI, I unplugged from wall for 15mins and turn it back, then I tried my PS3 and worked.

If not there is a firmware update on the website however it needs to be uploaded by a "technician" via USB drive mine has a USB port but there is no update for mine.

Let me know if it works
