Followed by a bright white/rainbow colored circle in the center of the black screen. the tv also makes a loud clicking sound while this is happening. i have to keep pressing off for the television to power down, and sometimes will not turn back on. this normally happens when there is a bright flash on the screen, then it freaks out. i have my contrast set to zero as any seems to make it worse... i hate this tv.

This set has a problem with the color wheel falling apart, which if one of the segments should fly off while the set was on it may sound like a loud pop, and the buzzing sound could be mechanical in nature with the wheel being off balance. If smoke appeared after the loud pop, then it could be a capacitor blowing in the power or video circuits. This model uses two different types of Color Wheel assemblies, either an L3 or a L6 and it would be listed on a white label on the Light Engines metal frame. Hope your solution is this easy. Bill
Yes,the problem is the colors wheel it dead.That one of the cause by the colors wheel,other are alots of squiling noises and making very loud buzzing sound.The cooling fan that u think is overheating,does it stop sometimes,when the tv is still on?Yes,than replaced it also,no than it still ok.Just hire the tv repairman,the parts he'll take care of it,don't order the parts,u might get the wrong parts or different sizes,that will not fit in ur tv.
First set the color to 0, the TV should be in black and white. if there is a purple or rainbow color then your tube may be failing. Most default settings are when everything is half way(centered). If this dosen't correct the issue than there is an issue on your main board.
you have a shorted green CRT that is affecting the other crts the short is internat to the crt that leaves what is called retrace lines. if the set is more than three years old then replace all three guns.
When you replace the entire board in a Zenith TV, you must make the adjustments to align the new chassis with the old picture tube. You must adjust the CRT bias and drives as well as the horizontal and vertical parameters. On the older boards there were controls on the main and CRT boards but on the newer boards the adjustments are made with the remote control after entering the service mode. Tune in the shopping channel QVC, set the color and contrast to minimum and lower the brightness until the picture is just visible. Set the CRT bias settings for a pure black and white image, then increase the brightness and contrast to get a very bright picture and if necessary adjust the drive settings so that the bright picture is pure black and white. Return the video settings to normal and then adjust the vertical and horizontal settings so that the info boxes on QVC are centered top, left and bottom. If you are not sure that you can do that right then have a qualified tech handle it for you.
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.
