SOURCE: On my LT42HVi with HDMI input source, the image comes through with a lot of green then will change back to normal color. Switching cables or HDMI input port makes no difference. Using normal TV inpu

Sounds like cable output is not correct
Look at cabling for loose connections cable to splitter if you have one or into cable box.If you have a cable box try unplugging it wait 1 minute then restart see if that changes output signal. No change? cable box or signal in is suspect,

I have a sony bravia 40 inch hd tv. i also have a comcast hd box that always worked on the tv through the hdmi. One day i was having trouble with cable box so i unpluged it to reset it. now my tv will...


Your PS3 working doesn't mean a thing for the cable unless you are using that cable for your PS3. I would bet you have a bad HDMI. They are pretty sensitive to being bent. Try replacing that first. The other thing to check is to first make sure you have the proper input selected on the TV for where you have the HDMI plugged into on your TV.

No longer getting video feed through Home Theatre receiver


HDMI ports 5 and 6 on the back of tv no longer are working. (We had a series of thunder storms so don't know if that is how they got damaged or if it was something else) but moved HDMI input cable to HDMI port 4 on tv and everything is working again. Service call placed for warranty service on tv to repair bad ports.

LC32OEM9 says Not Supported Format on HDMI Input. It worked when we first hooked up the TV. Then it started working sporadically now it very very rarely works and when it does it only works for maybe 15...


I'm thinking the Comcast DVR box maybe putting out weird HDMI signals and the TV can't translate it. I would call the Comcast people on this one.
In the meantime, I would try finding another source the uses a HDMI cable to rule out the TV as the problem. Basically, testing the TV to see if the problem still happens when you use something else than the Comcast box. Try a Blueray player, Playstation 3, or Xbox. Just something that uses a HDMI cable.

Close captioning on HDMI


The TV will not display closed caption with HDMI input. It must either over-the-air (antenna) or composite input for the TV to manage CC.

To get CC with HDMI from your Comcast DVR, you need to configure the cable box. Instructions can be found here:
http://en.wikibooks.org/wiki/How_to_use_a_Motorola_DVR/Setup

If you want CC all of the time, this works well. But since you must power-off the cable box to change the setting, switching CC on and off is a real pain.

Your set-up is similar to mine (Sharp Aquos 46" and Comcast DVR). I have the composite output from the cable box going to a DVD-recorder and on to the TV. Whenever I need CC (usually to catch some mumbled dialog), I just rewind the DVR, and switch the TV input to the composite input. Then I switch back to HDMI to continue watching in HD.

Poor Picture Quality


Try another cable box on the TV. I have seen these fail and cause problems. If the TV is okay with a DVD player, and not good on the cable service, most likely the fault is with the cable box, or the HDMI input circuit in the TV.

With the process if elimination it is possible to functionally work out where the defect is.
It is possible to have any TV fail. Both new and old sets can fail. Naturally, the older the set the greater the chance of failure, and reliability decreases with age and or use.

How to Hook up HDMI from Comcast Motarola Cable Box


Connect the HDMI outputs on your various components to the HDMI inputs on your receiver. Connect the HDMI output on the receiver to the input on your TV. HDMI incorporates digital audio, so no need to buy optical audio cables. If your receiver does not have HDMI inputs for all your components, you will need to make a choice. HDMI = Best, component video + optical audio = second best, S-video+ optical audio = third best

No sound on NON HD channels


I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.

Closed caption problem


I had the same issue... here's what I did.  If power off your cable box, then press the menu button, there's a selection to enable or disable Closed Captioning.  This works for both HD series Motorola boxes Comcast offers, at least in the Minneapolis/St. Paul area.  Hope this helps!
