Video signal breaks up and becomes scrambled, when set to HD stations off of my cable box. TV has only two component inputs for HD, both are not working. I have changed cables, changed cable boxes several times, and still it doesn'r work.
Spny tech came and adjusted sync and reset TV, but it went bad after an hour. The cable company brought their own LCD monitor in to my apartment, and the box worked, so as far as they are concerned it is the TV that is bad. It worked like a charm for two years at my present location.
Composite inputs, my DVD player going in component, and regular (480i) stations from cablwe box all work with the TV, but I should be able to see full screen HD like I used to do. Help!

From looking at the back panel of the TV, the DTV input can be configured as a component video. The M-Link/DVI-HD port is also a DVI with HDCP port and maximum signal handled is 1080i. The M-Link should work with an HDMI to DVI cable or adapter. For this to work, the source must not be a computer or another device using the default computer video output (computers give RGB output). The DTV port would need an HDMI to Component video converter. See this page for some examples: http://www.hdtvsupply.com/hdtocoad.html . The first one in the list (for Netflix and Boxee among others) will give 1080i out if the source is set correctly.
Most DVI-HDMI cables are single link. I've seen some examples where DVI-I (single link) and DVI-D (dual link) cables are not interchangeable. If you have video problems, check your cable. An HDMI to DVI adapters will let you run an HDMI cable up to the TV and then converter at the TV as a separate connection.
Since this is an older first generation (1999) HD TV it may not be compatible with newer HDTV receivers because the standards back then were different - Make sure the HD cable box is plugged into the HD component inputs on the back of the TV (not the DVD inputs) and that the menu setting on the TV is set to DTV (not RGB) video. This TV will only accept 480i and 480p signals on the DVD input. Also the HDTV input will only accept 480i,480p and 1080i (it will not work with a 720p signal,make sure your cable box is not set to that mode)
COMP 1 and 2 are for 480i/p sources. Hook it to the 1080i capable on the back. Also make sure the HD DVR is outputting 1080i not 720p. The Mits can not disply 720p and will show a scrambled screen if you try to.
I had the same problem
you have to set up the componant on DTV.
the signal my be hd 1080i and the only connection with componant that can support this is the DTV port.
the other componant connections only support 480,
First of all, is your blue "HD" light lit up on the front of your Uverse box?
If yes, then you're in HD
If No, you need to check your connections from Box to TV
1.Those Red-Blue-Green cables are for video only, they don't carry sound and shouldn't be connected to audio outs. Audio needs a seperate cable. Make sure your Red isn't on the audio out which is also red. Make sure your blue and green aren't switched with each other either. Check that at both ends.
2. Try an HDMI cable. It will carry audio and video together and it's one cord instead of 5.
3. What brand/model of TV is it? Is it an older projection TV? The HD tuner might be shot. The individual color tubes commonly fail after a few years.
4. Are you selecting 720p or 1080i from your TV's menu or from the Uverse menu? You'll need to set it through the Uverse box, not the TV.
5.Follow -Menu -Settings -Aspect Ratio to change to 720 or 1080. This should start an autotest which will scramble your picture for about 5 seconds, then bring you back to a menu asking you to keep settings or revert back settings. If you never see that question pop up, then your TV isn't supporting the HD, and you settings will be rolled back automatically. If the question does pop up and you can read it, select "keep settings" and press OK. Your blue HD light should come on the front of the box now.
Most HDTVs cannot properly stretch incoming HD signals, however, if the
programme is true HD, you should not much of the image off-screen -
most new HDTVs have about 2% overscan and the tickers should be on
screen when watched in the appropriate stretch mode.
I also have a Hitachi 53SDX89BA and I bought it with the same assumption as you: that it's HD ready. The specs in the manual states the following: "Full 1080i HDTV Capatable with Set-Top Box". I beleive this means that it does not include an HD tuner, but that it is capable of handling up to 1080i resolution. Normal (non-HD) resolution on this TV is 480i.
So here's my problem: Until recently, I wasn't using the HD settings on this TV because I don't have a set top box, nor do I subscribe to any HD content from my cable provider. However, I just purchased an XBox 360 along with an XBox 360 HD-DVD player (it's an XBox peripheral that works with the game console). The Xbox asks you to choose the resolution output (480i, 720i or 1080i) to match your TV's HD capabilities. When I select 1080i output and change my TV's settings to receive an HD signal, the picture quality is amazing. However, the video signal seems to get lost ocassionally (i.e. TV picture gets scrambled) but then it comes right back. This does not happen when I select a 480i output on the Xbox...but of course, the picture isn't as crisp and clear as a 1080i picture.
I don't know if this is a problem with the TV or with the Xbox. Has anybody else had this problem??
i know this problem, happened to me with the comcast Motorola HD receiver box. The key is with the setting in the cable box.
Switch on the TV.
Set the channel to normal tuner channel 3 or HD input.
Turn off the cable HD box.
Press the Menu Button on the Cable box or the remote.
You should see a Menu.
Use the cursor keys to navigate
The default setup is also one of the option, Right click on your cursor keys acts like the computer keyboard enter key and applies the change.
The default setup is 16:9, the shacking would happen if you have set the picture type to "PAN SCAN". change it to either 16:9 or 4:3 Letter Box. The shacking should stop.
Hope it helps.
