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?

It sounds that the video output section circuit bard to this TV have some loose solder terminals. Resolder all the suspected solder terminals by applying a little more solder. The video output section board can be located at the neck of the picture tube, will directly plugged on to it. Check it. If you wish to know more details about single color display screens, check this site. It has details to that problem. Pull up previous posts there, either by its left side bar, or view it in Timeslide option.

The colors of the rainbow cover most of the screen over the picture

What you decsribed can be from 3 different failures. 1) this unit is a CRT based TV and may need a simple degaussing procedure (remove magnetism from the CRT) 2) the electronics that syncronizes the color to the black and white component of the video is not working correctly (burst circuit) which would require a trained technician to repair. 3) the mask of the CRT has come lose which would require the replacement of the CRT.

You did not mention if this symptom is on all channel and inputs. If not then the cause could be external. The 3 causes above would require a technician to fix however if the cause is external you can address that issue yourself. Simply remove all connections , cable, satellite, DVD, VCR, etc and turn on the TV use a known good video audio source to determine if the symptom is still veiwable. If not then the TV is most likely not the problem.

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.

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

The description of the problem points to the picture tube being bad because of the rainbow colors,as far as the white lines you might have an open resistor in the crt board,a qualified technician should take care of the problem if the set is repairable and He will know as soon as he sees it.Good luck.

Color rainbow in picture

Your problem sounds like someone got a magnet too close to the CRT. This can be removed with a degauss coil (which you probably do not have) or it will eventually go away if your built in degauss circuit is working. Everytime you turn on the set the circuit degausses the crt so colors can be displayed properly. If the circuit is not working you will need to have a tech repair it.
