Hi all switching to a PC to serve karaoke and for some reason all I get on the TV is a black and white image?

My setup is as fallows

PC s-video out to RF modulator s-video in, out on f style coax to TV

I get the image but it is only in B/W?

Thanx in advance

Chuck

P.S. I'm using a evga geforce4 mx 440 vid card

The hardest part about doing karaoke is getting the TVs hooked up and working right.

Try switching the channel up and down.

One more thing...does the RF modulator have a 3-4 channel switch? Try changing that back and forth too.

There should be an OHMS switch on the RF modulator with options for 1K or 75. Make sure that 75 is selected.

Well hell did I buy the wrong thing? Mine dosn't have a switch for ohms? I'll get the multi meter out and check to see what it is set to guessing it is internal and maby I can add a resister to it to bring the ohms into spec?

Ok swaped out the TV from a 13 inch to a 20 inch and I have color now but it is quite grainey any thoughts? Tried differant cables and even took the switch out of line so it's a straight run from the modulater to the TV.

My new RF modulators have an adjustment knob that you turn with a small screwdrive. It adjusts the picture from black and white all the way to oversaturated color.

Grainy picture could be a lousy coax connection or the end of the cable is going bad. OR.....

What channel does you cable company broadcast on? Some use 3 and some use 4. If yours uses 4 then you need to put the TV on channel 4 and the RF modulator set to 4 also.

The hardest part of karaoke is the TVs.

Ok so I returned the RF switch cause I suspected it was bad. Got the new switch in and now the hp splash screen and the windows logo screen come up with VERY nice color but when windows loads it's back to B/W on the tv? At this point it has to be a softwear problem but I realy only know enuff about computers to be a danger to myself. Anyone have any suggestions?

I can't say that I can think of a really good reason for why this would work, but since it's only happening when Windows loads, have you tried using reduced resolution for your secondary (TV) display?

I would make it (#2 Monitor) the same as the computer screen (#1 Monitor). The computer screen is working in color isn't it?

okay did i miss what program it was and where you got it?

also all of the following that others have stated are true...

Coax should be high quality the thinner the cable then more loss of signal.

RF modulator should be set on 75

Also if you are using a splitter check it... it could be bad.

your video card could be wrong too..

just my thoughts!
