RCA p46924 Can't Post

I work in a nursing home, and our resident's 46" RCA went black and white back in September 2004 (7 months ago). The television is 2 years old. The repair center out of Lansing came and "fixed" it. 1 day later, it was again black and white. I called them back, and they threw everything they had at it, and kept it for 2 months. Upon return, as I was hooking it up, it again went black and white. Needless to say, the repair company gave up. I called another place. When they picked it up, it was in black and white. When they got it to their repair center, it was color. They tightened everything, brought it back and handed me a bill. 5 Days later, you guessed it, it went black and white. I called them back, and they pulled the board out. They sent it in, and a month later it was returned. Not a day later, it is again black and white. If I had the money in my account, I would simply throw this thing out and buy a new one. I haven't paid anyone for repair, because they haven't fixed it. Does anyone have any ideas?

Check your antenna hook-up. Sometimes a weak signal will result in loss of color. I would assume that they adjusted the AGC but?

Is that model a CTC169 chassis? If it is there is a diode that goes leaky and will cause it to go black and white. I remeber the part number is 164589. I just don't remember the location. I remember it's on the 13 volt supply. Sorry that's all i can remember.

I called the guy who's worked on the tv and he said the chassis is a CTC195.

Try resodering the tuner cover. they had trouble with the grounds on this tuner board section just like the 177 and 187 models. They get bad ground points in them.

Well, the television's board was sent to a service center. After a month, the repair guys came back and low and behold, the television turned black and white once again. They came back, sent it back in. 2 months later they brought it back and said that the company can't find anything wrong with it. The repair guys say that we must have "interference" in our building that makes the television turn black and white. Does anyone have any suggestions?
