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

We have owned our Set for 3 years - problems started this past week end. Bought a HDMI cable Hooked up Sony HD DVR and watched 1 show - worked fine - then sound stopped working through HDMI.

1 day later the component video inputs stopped working (sound was still working) The TV tuner still works and I can watch the DVR when using s-video input. So it appears to be the inputs themselves - any ideas?

Right now there seems to be many people with the same TV problems with sony and HDMI cables. Most of the solutions are resetting the TV and sony product. Try leaving your TV unplugged for a hour to let it reset itself.

HOW DO I PLAY A DVD USING Hitachi Flat Panel Television 32HDL51 (ITS CONNECTED THROUGH HDMI CABLE)


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 brought second hand Hitachi tv which just comes up that it has no signal. To retune i need a 4 digit code,is there any way i can by pass the code or put in something that the Tv will accept.


Hi Annette.

I'm not sure what level you're needing a code for. If you're looking for unversal remote codes to try to pair a remote to the TV, a listing can be found here
4 digit codes for TV sets including LCD Plasma and Panel TVs GE universal...

I'm not finding anything else about Hitachi TVs and a 4 digit code.

Is this 'no signal' coming in off of a cable, or off of broadcast TV? You may also want to check if there are multiple inputs and you're on a not-plugged-in input. For instance, the TV may have 3 HDMI inputs and a set of component video inputs. If, say, your cable box is connected to HDMI 2 and your DVR is plugged into HDMI 3, then if the system defaults to HDMI 1 when it turns on, perhaps it's showing some error code. You should have some sort of input select function. Try cycling through your inputs to make sure that the set is OK playing from other canned input like a DVD player. If so, then move that input through the imput ports to make sure they work.
If the TV has a direct cable coaxial hook-up, most, if not all cable companies anymore only broadcast in encrypted digital, meaning you'll need a cable box or something like a TiVo with a special cable card to see anything.

More specifics would need the make / model / year of the set.
Hoping this helps!

When the tv is turned off for hours then turned back on the pic. is snowy and the color is all messed up . it takes up to an hour before the pic. is back to normal . this is a Hitachi 50v720 any ideads on...


The simple test I would make is hook something to the rear audio and video inputs and see if when cold you have the problem there.

If your main signal in is via the cable fitting make sure cable is connected and if the set does not display the issue via rear audio/video jacks you can (most sat and cable boxes have this) route your signal via an unused set of audio and video jacks thus bypassing the tuner

Problem using Audio 3 sound inputs for HDMI video


Normally this problem is simply a matter of selecting the correct default audio playback device in the Windows control panel (sound option).
Check the Playback tab and set the default device to either DVI or HDMI.

This one is easy. WHen this happened to me, I simply called GE extended warranty service up and bought an extended warranty. I waited 30 days and called them up with my problem. A repair man showed up a few days later with the 1200 dollar light engine and installed it and left. Then I called GE up and cancelled the warranty. Total cost?: 48 bucks

Best solution to integrate Hitachi P50S602 into my B&K preamp


Hi, That is the best way. That connection allows you to take advantage of the panels audio features like sound leveling. The panel has a digital audio output(optical)which is good. By passing the video with the HDMI is the right thing also, the less connections in HD the less loss. You made the right choice ya Fixya yaself!

How do i use mdmi


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!!

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.
