Open Question

Hitachi 46W500 component video is scrambled

Both ot the component video inputs on my Hitachi 46W500 have stopped working. The channels show up as scrambled, and you can't see anything, but the audio works fine.

If there any way to update the firmware on this TV, or any way to fix this?

Thanks.

    Thank you for the quick reply.



    I have tried two different component cables on both of the component inputs, and it is the same thing. Same if you wiggle the connections.

    What piece of equipment are you getting the signal from? also does it have a different type of signal output you can use like a s video or a/v or hdmi, something along that lines, i would like to narrow down the cause to just the tv by seeing what we are getting out of the equipment.

    Have you tried a new set ove component cables? Does the picture change if you gently wiggle the connectors at either end?

SOURCE: Hitachi 46W500 46 in. TV/DVD... Problem:

Hello there. This is a really "easy" fix, all you have to know how to do is use a phillips screw driver! lol

First unplug the tv to reduce the chance of getting shocked. Remove the speaker cover, it'll pry off from end to end. Next, in front of the dvd player, you'll see several sets of screws; a couple of them will loosen the cover that has the dvd buttons on it and the other ones will loosen the cover for the dvd player. Once you get the button cover off, then you'll be able to get at the last screw that's on the dvd cover. Once that's off, then you'll see the actuall metal sub housing that the player sits in. Take off the four screws and simply pull the whole unit out. Be careful not to pull it too hard our all the way out as you'll have to undo four wiring harnesses from the rear of the player. After that, it comes out.

Now, I looked around and found this company that sells replacement dvd players; new and rebuilt. I called the company and talked with a young lady and ordered a rebuilt unit. There will be a core cost of $1 (meaning you'll have to send back your old unit to get back your $1). The new ones cost $259.45 and rebuilt cost $189.67. The part number is UE22181. The company name is Vance Baldwin Electronics (www.vancebaldwin.com) (954) 723-9191 or (800) 432-8542.

I challenge all who want to do this to NOT waste your money on getting someone to do this for you if you have to pay a lot. I'm really mechanically inclined (I rebuild cars/engines as a hobby) and this on a scale of 1 to 10 is a .5. ;) Good luck.

SOURCE: lose audio to receiver when connecting component video input

I don't know if it's firmware or hardware, however, it is NOT a problem, it is the DESIGN -- and an asinine one at that.

Essentially due to copyright issues with HD video, they CAN NOT decode the video to an analog output source. That's all fine and good, however, the audio never fell into that copyright issue. So you should be able to carry though the audio signal from those sources (since in the case of the component input, they're analog anyway). I think Hitachi is the ONLY company that just disables ALL analog outputs when it senses the video signal on the component or HDMI inputs (and you have the tv set for that input). They really should have ONLY disabled the video.

I had a half hour conversation with customer service, begging them to 1) file a complaint to fix this in the next firmware version, or 2) let me speak with an engineer to give me a hack -- obviously they didn't do that :(

The funny thing is, they WILL allow the Optical Audio output signal to carry though.

I've now been frantically searching the internet for information on how to bypass this ridiculous design 'feature'. As this TV isn't that popular, there's not much info out there on how to do so. So, I wouldn't know if I can simply try to attack the firmware code, or, if I actually have to take off the back of the TV and muck around with my soldering iron -- I'm hoping firmware.

One test shows that the control signal to SHUT OFF the entire analog outputs (audio and video) is on the 'Pb' (blue) input of the component video. If I have that one cable pulled out, I can get the Audio out to work and hear everything on my external stereo -- obviously I have a completely jibberish and unwatchable picture though. Once I plug in the 'Pb' cable, the picture comes in, obviously, but the external stereo sound cuts off.

At any rate. Just to reiterate, it's a design issue, and Hitachi seems unwilling to address the HD video copyright issues any other way. I am going to obviously send them a letter by mail telling them how their 'sledge hammer' approach to this issue is ridiculous when there is a 'scalpel' approach that is completely legally viable -- and all their competitors do it that way.

For this reason I now regret buying this TV.

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.

Changing inputs on hitachi tv 46w500 with out a remote


The Hitachi 46W500 has an Input button on the front of the TV. (This is the second button from the right. The right-most button is the Menu Button.) You should be able to press this repeatedly to switch between inputs.

If the Front Panel Lock is engaged, you need a remote to unlock this. (Only the Power button works when the FPL is engaged.) A universal remote which has a code that matches that needed to get the Menu button to work will do the job.

I hope this helps.

Tried to hook up hd cables and seems good but no audio tried to hook up but can't get to work


You cannot get AUDIO from Component Video, as it is only VIDEO, you must get another set of Cables RED & WHITE, and connect them from the AV, AUDIO Jacks, OUT on the "Sender" The DVD, Receiver etc, to the AV AUDIO IN on the TV. So you will have 5 Cables connecting BOTH Video & Audio. The Component Video, uses Blue, Green, & Red, these go color to color on the RCA Jacks at BOTH ends PLUS the Red & White Audio, color to color at BOTH ends. .Hope that clears things up.

I have a Hitachi 53UDX10B 53 in. Rear Projection HDTV.


Hello iehoryna,

The answer is yes, you will be able to pick up and display HD channels. You will have to use your component video cables between your cable box and your TV. Component video will allow you to view low to medium end HD pictures.

I hope this helps,

Thank you,
