Hello,
This indicates an Automatic Gain Control (AGC) problem often caused by a dried up capacitor. You will probably need a schematic to go much further. This could be a problem in the tuner, IF, or video amplifiers.

The following assumes you are sure the signal source is strong - try a VCR or other local one (channel 3/4, not the RCA jacks).

(From: Glenn Watkins ([email protected]).) Substitute a variable voltage source for the tuner's AGC voltage. Most of the time the range of AGC is from 1 to 7 volts. If you can get a decent snow free picture with an external AGC source, then the tuner is probably OK.

This is will require you to open the back cover of the television alongside an ohmmeter to read components on the printed circuit board of the television..
Take care

When hooking up HD Cable box I get "not supported

You most likely have to set the Cable Box to a specific resolution. Because that model only provides 720p/1080i, the box must be set to match that. You may need to use the yellow/white/red Composite output on the box to the tv first, so you can access the boxes menu and set it to 720p or 1080i, then I recommend using Component cables (Red/Blue/Green with white/red for audio) out of the box in to the TVs "Component 2" input. Now you should get a good HD picture. If you still can't get it to work, give me a reply with details and I will get back to you.

57H83 57 in. Rear Projection HDTV Television: I have a Toshiba 57H83 and recently purchased the ...

I would suggest to leave your directtv hd/dvr box connected the way It is.
The HD Colorstream 1input on your TV should work just fine.
This TV does not have an HDMI input but you can buy an adapter and connect to DVI/HDCP IN and that might be able to get 1080i video resolution on your TV.

HDTV CABLE NOT HOOKED UP/WORKING

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.

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.

Hitachi 53SDX89BA

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??

Sony 57 Inch XBR 2001

I don't have the XBR, but on my sony, using the cable box remote, I had to go into menu/display/etc. and mark the 1080i, 720p, and 480i settings. you usually get a "if you can see this" comment if your tv accepts the settings. for standard tv i set the screen to normal, and when the upper channels go to HD, they auto go to full screen. Sounds like you are using the component cable, and also make sure you are on the video port of remote, and the the TV input. The above worked for mine. Hope it helps.
