For some time, I have had an intermittent signal problem with my HD and low-def channels. When there is an area of subtle color change on the screen, I get odd colors and color gradations. For example, when I watch hockey, teh white ice surface has yellow blotches on it, though white uniforms look ine. When I have a display with subtle shade changes like the directy blue or green intro screen, the color difference is greatly exaggerated on the TV screen.
This only happens with my HD input; my DVDs look fantastic, so I don't think it's the TV. I have checked conections and the pointing of the dish and they all seem to be okay.
Also, on what source is the problem happening, through sat or through off air antenna?
If you're on HDMI I'd try component. Then, playback the affected video and see if it's reproduced w/ component.
If it's on ota only, you may have a loose tuner cable inside. It's easy to fix, you need a torx t-10 screwdriver. Unplug the unit, take the 5 torx screws off of the back cover, and on the right side you'll see 2 cables running from tuners in the front to a splitter that connects to the tuner for ota on the back right. Just make sure the connections are tight with your hands only, don't over tighten them. Also, make sure you don't touch the power supply when you have the unit open!

I had the same problem with HDMI input to the RX-V373 from a DirecTV receiver. The RX-V373 volume display and menus on the screen are HD only, which forces the monitor to switch modes when viewing SD.
My solution was to turn off 480i and 480p signals from the DirecTV receiver, and also turn off its native output. The DirecTV receiver then upconverts SD signals to HD. Changing RX-V373 volume then doesn't affect monitor video mode.
There you can reset to factory settings. After you set the clock and date, it will ask to scan for all active channels and it will block out the channels it does not find a signal for. Let it complete this task (20 minutes). It asks you for the type of signal but just leave the STD setting for both options before starting the channel finding routine.
When complete, go to channel 10 to see what show is on (low def version). then click down to channel 2 and then push the channel down button several times again to try and find the HD version of that show. (HD channels are high-number channels that are easiest to get to by scrolling below channel 2. Most will have a hyphan in the channel name (e.g. 93-2; 94-1, 94-2, ...).
If your TV goes directly to a 2-digit channel, they you do not have an HD tuner in your set. I doubt that is true so I think you will find what you need.
It the tv,it have intermittent video problems,with the Tuner board.That the board in the tv,where the cable company broscating signal cable plug into it.U used a HDMI cable to plug into HDMI port hub to get ur HD signal.Take it back talk to Best Buy,tell them this tv have intermittently not supporting HD frequencies changes.Tell them upgrade the tv frameware software for u
.Or keep presisting give u another replacement tv.
Mine has done this from day one, appears to be a resolution problem. All I do is go to a HD channel let it tune in and then go back the the SD channel and don't have to worry about it until next time the power has cycled.
I assume that you are dissatisfied with the quality of the picture on
the HDTV. Are you feeding it with an HD signal. First, it
must be an HD source, either over the air HD or a cable channel in HD
(not all "digital" signals are HD signals). Second, you must be
sending it with the proper cable, either HDMI or at the very least RGB
Component Cables (not composit video).
It is quite common to see standard definition on HDTV's actually look
worse than on standard def sets. The reason is the extra pixles
availble on the HDTV make you realize how low of resolution the
standard def signal is. Instead of it just being fuzzy or
unclear, it will actually look bad.
well you would need to hook up cable box to dvd recorder. the only draw back first off is one you cannot get hd onto a dvd. you can down scale and it will seem a little cleaner than standard def but of coarse it will never be high def. I'm not to familiar with the motorola boxes but if they offer dvr's in your area i would suggestgetting one you can record all channels then afterwards transfer them to a outside device. but as i said before high def cannot fit onto a dvd unless you plan to copy one movie to 6-7 disc. Just keep in mind a standard high def channelcan only fit 2 max on one freq due to the amount of data transfer as opposed to 10 to 12 standard def digital channels
When you are changing channels you are using the tuner of the sat reeiver. the tv does not know you are changing a channel . It is just receiving a constant signal from the SAT receiver. I would suspect a problem with the receiver. Try another one first .
On any High Def TV, the reciever you need for this set, which does not have a HD receiver in it, is half the equation. Most HD channels have some HD content mixed with SD content on the same channel. SD content on HD signal from cable or satellite tends to be slightly blocky due to the native signal resolution and the resolution of HD (1080i/p or 720i/p).
