I have a Zenith B27A11Z and the color is not working on it. I turn it on and its in black and white. Although the little box in the corner of the screen that tells you which channel you are on shows up in color. I am very confused about this for sometime now. I had given up for awhile after searching an endless amount of forums for a solution to the problem and never finding one. Can somebody please help me with this???? Im almost forgetting what its like to watch tv in color lol. Any help with this would be much appreciated!!

Thank you to anyone willing to give some advice :D

On screen display handles colors differently.
I presume you've tried the color level control (indicator) up and down?

Did set ever have color? And do you have test equipment? (Scope in particular)

Yes i have tried the color level control numerous times in hopes of a different outcome, but still the same.

And yes the TV was in perfect working order when i recieved it from my great aunt. Although i was wondering, when my mother hauled the tv back to the house it was loaded in the car face down...would that possibly have something to do with it??

Im not a professional technician by any means so thats kinda like a foreign language to me lol. But i took the back of the tv off and found a piece in the micro processor area that was labeled 9-2109. And also i found the part of the board that was labeled ICX2200. And a toshiba piece with the number TA1268N is in that spot. Is the TA1268N the video processor?? So i need to replace the TA1268N?? Where do i go about getting my hands on one of those??

The numbers in parentheses are the part numbers right?? Cuz i cannot find the 221-1165 (it looks as if its a TA1268N on the spot of the board marked ICX2200) But i DID find the CR2201 (224-27) Can i find these parts at my local radio shack? Or how do i go about getting them??[/i]

ICX2200 here:
http://www.mcmelectronics.com/product/TA1268N

Let's hope we can desolder / solder otherwise no point in obtaining.

ICX2200 is the location of the part on the board/schematic, numbers in parentheses are manufacturer's part numbers and TA1268N is the generic part number.

Gotcha. I have soldered before, although im not very good at it. I see that its a very small area to work in. I only have a high heat soldering gun. Will too much heat damage the board?? Do you have a soldering tip preference when working on boards?? Also, where would i find the CR2201 (224-27) online cuz it doesnt seem to be coming up in any searches i've made??

Transporting a set on its face is not a good idea. Glass can get scratched for one thing.

YES, too much heat will damage the board.

Something along the line of this for iron:

Something like one of these for desoldering:
http://www.mcmelectronics.com/product/TENMA-21-8240-/21-8240
http://www.mcmelectronics.com/product/WELLER-7874B-/7874B
http://www.mcmelectronics.com/product/CHEMTRONICS-60-2-5-/21-2170
Practice desoldering / soldering on a junk item 1st.

As far as diode, is it bad? Do you have a digital volt meter with diode testing capability?
