Hitachi 50V720 No sound with HDMI - no Component video inputs

Page 18 of the manual, you shouldn't need to do steps 2 or 3.

CONNECTING A COMPONENT SOURCE WITH HDMI or DVI CAPABILITY TO INPUT 1 or INPUT 2
1.Connect the HDMI or DVI to HDMI connection cable from the output of the HDTV set top box or DVD player to the HDMI input as shown on the AVC Center below.
2.With DVI output, connect the cable from the AUDIO OUT R of the HDTV set top box or DVD player to the INPUT (AUDIO/R) jack.
3.With DVI output, connect the cable from the AUDIO OUT L of the HDTV set top box or DVD player to the INPUT (AUDIO/L) jack.
4.Press the INPUTS button, then select INPUTS 1 or 2 to view the program from the HDTV set top box or DVD player. The VIDEO OSD label disappears automatically after approximately four seconds.
5.Select ANT A or B from the INPUTS menu to return to the previous channel.
NOTES:1. Completely insert the connection cord plugs when connecting to rear panel jacks. The picture and sound that is played back will be abnormal if the connection is loose.
2. The HDMI input on INPUT 1 or 2 contains the copy protection system called High-bandwidth Digital Content Protection (HDCP). HDCP is a cryptographic system that encrypts video signals when using HDMI connections to prevent ******* copying of video contents.
3.HDMI is not a "NETWORK" technology. It establishes a one-way point-to-point connection for delivery of uncompressed video to a display.
4.The connected digital output device controls the HDMI interface so proper set-up of device user settings determines final video appearance.

Have you tried replacing the cable ?

Hi! I will be more than glad to assist you. I f you are going to hook up your cable box - motorola to the sherwood receiver, connect an hdmi cable to the back of the motorola cable box, there is only 1 hdmi output there, then connect the other end to the sherwood receiver on the hdmi input, then connect another hdmi cable to the hdmi output and the other end goes to your rca hd tv.

for the sony dvp, you have only one hdmi out, connect an hdmi cable to the back of the sony dvp if u have another spare. connect it to the hdmi input of the sherwood receiver. there is only 1 hdmi output at the sherwood, so u need to use a component cable to be connected at the back of the sherwood receiver component output then the other end goes to the component input of the hd tv.

if you dont have anymore hdmi cable to hook up your sony dvp, u can use component cable, the connection will goes like this, connect a component cable on the output of the sony dvp and the other end goes to the sherwood component input then connect another component cable to the component output of the sherwood and the other end goes to the rca hd tv on the component input.

I hope this will solve your concern, if you have any question, u can get in touch..

Component ports can and do fail. You can get a replacement board from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

Yes, it will work. Be sure to use input 4 with the 3 rca input cables red/blue/green for video and 2 rca red/white for the sound. You need component video output on the PS3. http://www.sonystyle.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10551&langId=-1&productId=8198552921665061579&storeId=10151&INT=M:ak is what you need, if you don't have it already. Here's the thing. The PS3 will work on any set. You can hook it up with the yellow wire and red/white wire for standard def. or 480i. The component cables are for 720 and HDMI for 1080. Your set don't have HDMI, it has component input. The service manuel say's it has 720I available. You can see if the front has HDTV sticker..if it does, them for sure it does. Either way, the PS3 will work on your set. I'm 90% sure it's 720i as well.

It's actually called an HDMI......

you'll need to get an HDMI cable from circuit city (or someone like that). Plug in one end to either you cable box or your DVD player, and the other end into your TV. Go to your Input select (or source select) and select HDMI. If your cable comes from the Cable box, turn on your cable box.... if it's from the DVD player, turn on your DVD player... you're off!!

it sounds like the A/V reciever does not upconvert the component signal to HDMI. Not many do. The Marantz recievers will (SR6001, SR8001, etc..). Also bear in mind that HDMI cables are finicky and may require amplification over a few meters long.

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.

I started back in the day of tubes. A family would have one set and it would be a 19" black and white. There are different resolutions now. The components probably do work, but, they don't pass the 480i signal. The satelite converter's analog signal needs to be set to 480p and the DVD needs to be set to progressive if it does have that setting. If the DVD is not a progressive scan DVD, then, the only inputs that it will show on is the analog signal. Some of the dish converters have a switch on the face for changing the resolution. If yours doesn't then put it in an analog source and go to the menu and change it there. Then move it to the component input. Hope this helps.
