I can't get a signal because this tv don't have cable antenna terminal the tv has rgb terminal. I don't know what to do?


RGB is for a computer screen display signal and has nothing to do with TV display of channels. You must have a Component hook up, it is a yellow cable, a red and a white one. Yellow is video signal, the red and white are sound.

I have a proscan with no sound so I brought a


You hooked up the sound bar to the cable box red & white sockets, right. Now you have the soundbar hooked up to the TV red and white sockets. Did you notice any difference with the labeling on the two sets of sockets? The cable box sockets were labeled "Audio Out", but the TV sockets are labeled "Audio In"

AV signals are directional. Any socket labeled "Out" will give a signal from it for connecting to another device e.g. the connection from the cable box to the soundbar.

Any socket labeled "In" is designed to accept a signal from something else, but it won't give a signal out. So you can't connect the TV's Audio In socket to the soundbar's Audio In socket because both expect a signal from something else and neither supply a signal out.

Check the back of the Proscan TV. Is there a socket labeled Audio Out? If so, use that.

Rainbow static on Plasma Tv


The color static, if we are talking about the same thing, is usually a digital signal interference. Check cables, and digital converter if used.

No Video Signal - Black screen with Blue Bar that reads "No Video Signal". Eversince we got a new HD reciver to view our new Toshiba 40" tv in HD, we have been having this issue! Lately it...


One of the things an HDMI connection does is allow the TV and equipment to talk back and forth to each other. When you turn the TV off it ends this connection but when you turn it back on, it doesn't communicate correctly. The analog inputs don't do this that's why when you change inputs and go back to HDMI it works, because the TV reestablishes that connection. You didn't list the model of the TV but go to "http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/home.jsp" and click download. Enter the TV you have and click "GO". A list of downloads comes up and your TV may have a firmware update for it. There is instructions on how to do it. Even if this doesn't fix this problem, it is still good to do to avoid other problems. Another solution is to use component (Red/Blue/Green) cables. The highest resolution they support is 1080i, HDMI is 1080p. Depending on the model of your TV and what your watching though, you might not see a difference. TV2 will never have this problem because it is not connected through HDMI.

Im trying to connect my sega dreamcast which has red white an yellow av cable only, however my insignia NS-32E570A11 led tv only has for component connection with the blue green n red, when i hooked it up,...


Sorry, this will not be easy....

You need to locate a composite to RGB converter box.

Your Sega outputs a composite signal - Video (yellow) and audio left/right (white/red).

The TV needs RGB (red/green/blue) inputs on the component connection...your composite signal divided by three. There are converter boxes out there for around 70 bucks or so.

Are you certain you do not have a yellow VIDEO IN jack on your set? Every LCD and LED TV I have experience with has at least one.

I am trying to hook up my cable box so i can watch tv.


At the cable box input, connect the cable (probably labeled "Cable In" or "Signal In").

Depending on the cable box model and available inputs on your TV, connect one of the following (listed in descending order of video quality). Colored phono plugs must match the colors of the plugs on each end.:

  • HDMI (a single rectangular connector at each end - sometimes you need to connect the Audio separately with a two - line cable with red and white phono plugs).
  • YPbBr, AKA Component (Cable with Red, Blue and Green phono plugs, plus a separate Red and White cable set for Audio).
  • S-video (a single round connector and separate Red and White audio cables).
  • Composite (Yellow video cable plus Red and White audio cables, usually sold as a single set).
  • RF out on the cable box connects to ANT or Cable In on the TV with a coax cable.
The various options are always grouped in some manner on both the Cable box and the TV. On the TV, note which input set you use, for example, "Component 1". This is the input you will select to watch whatever channel you select on the cable box.

An unused output on the cable box can go to a video recorder. Some cable boxes may permit setting up two different channels for this purpose; others will only put out the signal from one channel at a time on all outputs.

You may, if you prefer, connect the audio cable from the cable box to a stereo receiver instead of the TV. Usually people connect the audio to the TV, then connect another audio cable from "Audio Out" or "Monitor Out" on the TV to the stereo receiver. That way the sound is from whatever video source is currently selected, and the TV remote control can be used to set the volume. TV sets with this option usually have a setting to turn off the internal speakers so you hear only the external stereo speakers.

Hi there,
My sister-in-law has exactly the same problem and is a common one with this unit.
I've spoken to a technician who says that:
1. Hitachi are withdrawing from Australia and there are VERY limited service centres left
2. The problem is a chip on the main board and depending when the TV was made will determine whether the chip is a plu-in or soldered on to the main board - if it's the latter, you'll be up for a main board at around $400
3. He couldn't get the price of the plug-in chip because he couldn't get through to Hitachi.

Cheers
