There should be 3 sets of video rca jacks on tv or receiver they might have put them on the wrong rca jack in which they just need to be moved over
usually the 3rd set of rca jacks are component jacks not for tv or video but for low output signals say like cameras and only one set of rca's can be used at a time svg on one of them rca's will over power the vid's. so have no picture

I have sound but no picture on my hitachi ultravision digital tv


When you use the remote control can you see the on-screen menus, volume or any stuff? if yes, then you may be lucky and have a cable problem. Can you try with another source (DVD, VHS) if you see video with them then you still can be lucky.Check the cables and the hdtv cable box. If you answered NO to any of the previous then its a TV problem and you can't fix it by yourself..

Is my Hitachi 61uwx10b ultravision hd ready digital tv ready when they switch over to digital vrodacasting or will i need a converter box,


This TV will need a converter box. It was made in the days before the digital tuner was required on big TV sets.

Just remember the converter is only needed if you get off-the-air reception with an antenna for local channels. If you have cable or satellite and get your local channels that way, you don't have to do anything. The change to digital will not affect you.

If you are now using rabbit ears or an old worn-out outside antenna, you might think about upgrading your antenna when you get a converter box. Signal strength is very important with the new digital broadcasting. Too weak a signal means no picture at all or one that freezes up or turns blocky. The antenna that worked for analog may not be adequate for digital.

Weak signal or channel not available


Digital signal requires all connections to be snug.. double check them. Also if you have splitters in the line, make sure that they are rated for digital, good quality (you get what you pay for) and the mhz is rated for 2 gig or better... if probems persist, you can install a digital cable signal booster... Amazon sells a motorola model that will boost the signal 12x. Got one this week and works great...
Good luck on this, let me know how it goes..

No picture, just sound, can still see cable directory


Sounds to me like you may not have service on your cable box. I worked for a large cable provider for years and that was generally either a faulty box or the box just needed a "signal" sent to it. Try to bypass the box complety and just hook your service directly into your TV. You may need to go into you TV's menu, switch it to the cable setting and then auto search, but most likely the TV is new enought ath you should be able to get a picture. We do know that it is not a problem with the TV since you are able to view other devices on the TV. If you get a picture then we have narrowed it down to the bow. Although this may not mean that the box is bad. First let's ensure that if is installed correctly and that the input jack is the cable from the wall and that the output runs to the TV. Again you have sound so i know this seems dumb but so can be cable installers. :) Since we know all of that is correct and you still have sound but no picture, I'm going to say that you most likely have a motorola box and on the front of it there is a small button that has a/b next to it. (most commonly found on motorola box but not limited to). If that button does exist on this box i'm almost certain that will correct your problem. If not you have a faulty box and should ask you cable provider to replace it.

DVI/HDMI Cable lost my pic and sound


Try disconnecting the hdmI cable and the dvr box.
Connect the cable directly to the cable input.
Sometimes the dvr boxes will cause this problem
after you connect the hdmi cable.

Normallly, if the format button on the remote for the television does not achieve the desired affect, then, a cable box or a satelite box is where the change needs to be made. For example: A Motorola Cable box needs to be set up to go to a wide screen when an analog signal is detected. It's difficult to determine the repair without knowing the hook up of the peripherals. Hope this helps.
