IM HAVING TROUBLE WITH THE INPUTS

Someone press the Source / Input button on the remote to a source with no input signal.

Hi EA.

Some of the answer will depend on the particular model of TV you have. Most flat panel TVs have multiple possible inputs, with some array of choices like HDMI 1, HDMI 2, Component, VGA, Cable that you can toggle through with your remote.

Most of them, in my experience, also will check first for inputs from the different components, and skip them if they don't show a video signal. In some cases, as was the case with my past Mitsubishi rear projection TV, each input channel had an option for either showing it or skipping it when cycling through inputs - that way if you just had Cable and a DVD player, you didn't have to cycle through 8 other inputs each time you switched.

If you're saying that a VGA input to the TV shows up fine on the screen, but other inputs don't, then that narrows it down and shows that the screen is working OK. I'm not completely clear then whether you have things plugged into other inputs like HDMI or component. if nothing else is plugged in, I'd guess the system detects no inputs from those ports and ignores them. If they are plugged in, but you don't see them, then you likely will need to activate or toggle those particular channels to be included amongst selections.

Hoping this helps, and Happy Holidays!

Hi,
First hook up another A/V input like your DVD player to this A/V input 5 to determine if the fault is in the TV itself.
Let me know if the symptoms still the same after connecting your DVD player to input 5 to assist you further.

Hello

Your TV will display all High Definition signals as 1080i True HDTV™ and all standard definition signals will be displayed as 480p.

Component Inputs 1-2
YPbPr(480i/480p/1080i)
These inputs can be used for the connection of A/V equipment with component video outputs, such as a DVD player or external HDTV receiver. Please see Appendix B for signal compatibility.
Input DTV (480i/480p/1080i)
This input is used to connect an external DTV receiver, and can be configured for YPrPb and RGB plus H&V signal types.

As a special feature, you have the ability to adjust the red and blue light beams in reference to the fixed green light beam. This process is called convergence. There are two separate memories for convergence. One, for SD 480i/480p signals; the other for HD 1080i signals. SD convergence should be adjusted while watching an SD source and HD convergence should be adjusted while watching an HD source.

Wide Expand: Enlarges the picture, cropping some of the image on both sides. This Expand format is useful to remove or reduce black side bars on HD broadcasts of 4:3 images with black bars. Available for analog 1080i, digital SD 16:9 and digital HD signals.

InputDTV
This input is compatible with most standard DTV and satellite receivers with component video (YPbPr) outputs. Compatible DTV signals are SDTV 480i/480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Please check the DTV receiver specifications before connecting.
This input is compatible with some DTV receivers using RGB with "separate H and V sync". Compatible DTV signals are SDTV 480i, 480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Industry standards for DTV RGB signals (systems, synchronization, timing, and signal strengths) are not currently established. These inputs will not be compatible with all DTV receivers that offer RGB, HV outputs. RGB, HV signals with less than 5 cables are not compatible.
If your DTV receiver offers both DTV component video signals and DTV RGB, HV signals, we suggest you use the DTV component video signals. Check the DTV receiver specifications before connecting.
Ok.

HI Tom,

For some reason I cannot reply to other inquiry would you please close the problem, I am glad that the configurations worked out for you.

************************************************************************
In order to configure the proyector for hd video you would need to change a couple of things in your set up.

First you would need to use hd cables, and not the rgb. You can purchase some standard high def cables at any best buy or radioshack, depending on the source device there is the standard high def out, the set of 5 cables, 3 video plus the 2 audio.

To enable the unit to support the progressive DVD signal, perform the following
procedure.

Connect the DVD player’s component output into Input A.
In the SET SETTING menu select HDTV-YPbPr for Input A.
In the INPUT SETTING menu highlight Sync and select EXT (HV).
The IDTV module disables itself automatically

Perform this procedure with nothing connected to the component input on the projector, otherwise you will get the an off/on flickering screen which prevents you from seing what you are doing when navigating the menu screens. Perform the procedure and then connect.

Let me know if you need anything else,

This television is having trouble with sync circuits. It probably has some component adding erratic noise voltage to the circuit causing the instability in the sync lock circuits. The solution is to locate the bad component with an oscilloscope by following the signal path with oscilloscope probe until you find the irregular signal and then replace the part. This part could be either capacitors or ringing resistors.It may also be a component in you solid state signal processor. You should have it tested in a service center and see if they can locate the bad components. Then see if it worth replacing with the cost of parts and labor. Hope this helps you with your problem.

sounds like theres a short in side with those connections, (possibly bad installation when it was assembled, may need repaired.

The component 1 and component 2 inputs only go to 480i and 480p. The Apple TV must be plugged into the DTV input which will accept a 1080i signal.

I just spent an hour trying to fix the VIZIO with the same problem. The screen had no picture at all, but could hear the sound perfectly!! But we i figured out the solution! UNPLUG THE CABLE BOX AND LET IT RE-BOOT! and it WORKED!!!!!
