Sounds like you might need a good cleaning or your tv has contaminated coolant in the picture tubes. or you just might need to adjust the screen control for the picture tubes.

    coolant is used in projection CRTs. it is usually a mixture of ethyl glycol and glycerin. it is used to cool the face of the CRT to prevent cracking and premature aging. sometimes the coolant can react with its metal surrounding or even the light being show through it there are many different ideas about the reason that coolant gets contaminated.

Screen losing color.. turning black and white


Your TV goes black & white, because your Wii could be NTSC or PAL which. If your Wii is PAL and your TV is NTSC then the TV will show a blac and white color. Since NTSC is for North America and PAL for Asia

Samsung HC-P4752W No Color


Do not automatically think you need to go into the service menu. I bet you 100 to 1 that you pulled out a plug or a connector somewhere OR one is not seated into the plug all the way. If the set worked with color before you messed with it, there is not a problem in the service menu. The service menu is not the fix all thing. it is there to make fine alignments and adjustments, and as a matter of fact, messing with a service menu even with the service manual is very dangerous. I have seen peeps ruin TV sets by messing around with the service menu alignments. STAY out of these alignments. they are not going to fix a problem that all of a suddenly comes up. Repair the problem in the circuit first. Good Luck
