DVD-TV Color problem

[Edifice]

Need alittle help here.

My friend has an old 1990's RCA 19" CRT television with only the cable port on the back and he bought a converter box to allow him to hook up a dvd player to an older television set.

Well, I helped him set it and the sound comes out, the picture comes out but it is black and white. When he turns the converter box off and watches his regular cable it's in color but when watching dvd's it all in black and white. We tried switching the settings on the box and the menus in the dvd player but to no effect.

Is there something wrong with the way it is hooked up or something wrong with the cables? Or is it simply the fact the tv set is too old?

Some help guys.

Are you using a converter box or an RF modulator(it's what you need for this to work)?
It should work...even on older tv's. Have you tested the DVD player, and RF modulator on another TV? Does the modulator have a CH. 3, Ch.4 switch? Is the TV on Ch. 3?

Yeah, we switched between channels 3 and 4 on the converter and it still comes out B&W. We did not test it on another TV though. I wonder if it is the RF modulator or the cables.

As the RF converter must trun and audio and video input into a output for the TV, your box might be only a B/W box. Do a swaerh on the model of this box and read the details. A second thing to check is the input gain. But likely it is only putting out a B/W signal.
