Rainbow of color when viewing DVD

T.V. works great; however, when I switch to DVD (video 1) the picture comes through but the screen is a horizontal rainbow of color. Our DVD viewing experience is not enjoyable. I did buy an "S" cord thinking the picture connection might be broken but that didn't help. Also, I checked the DVD player against another T.V. in our house and it worked great there. Any ideas?

Rainbow screen on 45" rca tv


Wow a lot of details but a few key ones left out.who refurbed it and why. Compact and layered circ bds make the chance of it a mechanical prob unlikely. initially sounds like its in the imaging board or color matrix assy. the rainbow the same every time does it move at all ? are there chunks of missing data? is the display throwing any kind of weird code? does it seem hotter than it should be? is it in a dusty environment? are there any high pitched frequencies to be heard ?The DVD combo is the picture only when you use the dvd or cable or tv live air signal? other than those questions I think we have it narrowed down Snicker no seriously many things go wrong with the slap together digital stuff these days and we're finding more and more that its a board problem and then by isolating symptoms we determine which board. some of the larger flat screens have 10-15 boards all manipulating the constant flow of endless digital information.
Unfortunately we as consumers have to make the decision on whether its cheaper to replace than to fix. Rule of the thumb these days seems to be if repair costs (labor and parts combined) come close or exceed 1/2 the value to replace ~~~~> then replace. Hope this sheds a little light on the kind of things repair techs brain goes thru. let us know how it all turns out~~~ S ps.. is it 32" or45"?? not that it matters

Rainbow screen aiwa tv,, screen shows different colors like rainbow// brushing a magnet infront of the screen fixes the issue temporary


Picture tube is magnetized. Manual degausing is required. already you have done this.

Since you say it is reappearing, you have to check the following.

1. Relocate the TV or relocate if you have placed any tower speakers
or home theater speakers close-by.

2. Check whether auto degauss functioning OK. In the MENU
check whether you switched off auto degauss option. If it is OFF
enable it to ON.

3. Finally re orient the direction of your TV and watch the rainbow
effect. Switch OFF TV, wait for 20 mts, and again switch ON.
Repeat the process. It should disappear.

Magnetic toys or any other devises using magnet will cause this problem.

Rainbow color effect appears when Samsung LCD plays Wii or DVD


Hello, I have a question which video inputs are you using for your DVD and Wii connections? The reason I ask is because this sounds like video distortion cuased by noise. If possible can you send a picture of the screen when it has this problem and send which video ports are being used? If it is noise in the video you may have a saw filter problem, or a decoupling issue. In any event I'll know more once you send those pictures and which inputs you are using for your DVD and Wii. Thank you, Shuttle83 http://www.electron-age-technologies-llc.com service@electron-age-technologies-llc.com

4.14.1 Understanding Viewing Features
Your LCD HDTV features four viewing modes and Picture-In-Picture (PIP)/Picture-by-Picture (POP) mode.
You can switch viewing modes using the remote control.
4.14.2 Viewing Modes
Normal Mode
The original 4:3 aspect ratio (1.33:1 source) is preserved, so black bars are
added to the left and right of the display image. Standard TV broadcasts are
displayed with a 4:3 Aspect Ratio. Movies in 4:3 Aspect Ratio may be referred
to as pan-and-scan or full frame. These movies were originally filmed in 16:9
(widescreen), and then modified to fit a traditional TV screen (4:3).
Wide Mode
When watching a standard broadcast or full-frame movie in this mode,
the display image is stretched proportionately to fill the TV screen.
When watching a widescreen (1.78:1 source) program or movie, the
display image fills the TV screen. If you are watching a widescreen
(1.85:1 or 2.35:1 source) program or movie, there will still be black
bars at the top and bottom.
Zoom Mode
When watching a widescreen (1.78:1, 1.85:1, or 2.35:1 source)
program or movie, the display image is zoomed proportionally to fill the
width of the screen. The top and bottom are cut off to remove most of
the source material’s black bars. This mode is good for programs or
movies with sub-titles.
Panoramic Mode
When watching a standard broadcast or full frame movie in this mode,
the 4:3 Aspect Ratio (1.33:1 source) display image is stretched
horizontally on the left and right sides to fill the TV screen. The center
of the image is not stretched.

Note: Viewing modes are saved based on input. For example, you lasted watched a DVD in widescreen
mode and then watched TV in standard mode. When you switch back to DVD input, the viewing mode
will return to widescreen.

Cannot view channels higher than 10 and cannot get DVD to come on


Dear althea, I cannot help you with the first problem, but as for the second, "DVD does not come On" and "Do not understand Video 1, 2, & 3 settings." it is very simple. YourTV has the sockets at the front Marked Video 1, Audio L and audio R, The y are in three colors - Yellow for video, red for audio right and White for Audio Left. Similarly, you have 2 such sets of 3 sockets - they are Video 2 and Video 3. This allows your TV to be connectod to three different Video sources - maybe a VCR, A Video game, and a DVD player. To view the pictures generated by your DVD Player, all you gotts do is connect the supplied AV cord from the rear of the DVD player to the front three sockets in the proper order - Video from DVD to Video of TV, Audio L & R from DVD player to Audio L & R of TV. Now press Video on the TVs remote. Press repeatedly till you get Video 1 displayed on the screen. Then, if you now play your DVD player - make sure there is a disc in it - you will be able to view the picture / movie. Good Luck
