Weird problem?

[FrankCastle]

Hi.
My plasma has 2 RCA inputs,1 is used for DSTV,and the other for my DVD player.When the 2 units are connected,my DVD movies play black and white.In order to solve the problem I have to swap the inputs,but then DSTV becomes B&W and the DVD plays fine.To view DSTV properly again, I have to swap the inputs to its original configuration.My DVD player and DSTV unit has no HDMI,so I have to use RCA's.Tried it with another TV and I get the same problem.What gives?

You have checked NTSC/pal settings?

^^^^ What he said.

Logically, it sounds like there is something wrong with the plasma's one input... So, check if there are NTSC/PAL settings for that input, otherwise it might be faulty.

Doesn't your DVD player have a component out?

Yes both tv and DVD have component.So I went out to get a component cable and hooked it up.Colour picture on dvd but no sound.I then used the RCA cable from tv to dvd but only used the audio white/red and viola,everything works now.
Thanks for suggestions guys.might have been plan B.
