PC to F-Jack with sound injected

[bimm25e]

So my little brother bought a cabinet and in a recent move his monitor went out.  He's more than a few hours away so I haven't had a chance to diagnose and he wouldn't really know where to start by himself.  Im headed down in January to ... fix it all up there....  and Im trying to get a plan-B together in case it isn't just a loose cable or blown fuse.


I picked up a 27" CRT television on the side of the road and took it home to dry out.  Fired it up last week and the picture is great the TV only has a F-Jack as an input though and though I think I found some info about modifying the chassis to accept RGB input on the onscreen display circuit, hes not a videophile and I would like to just keep it simple and use the existing F-Jack.


The JAMMA board is "Martial Champion" which sucks, So while I'm working I'm going to put a HyperSpin PC in the cabinet for him  This means I'll be dealing with a VGA signal.

Does anyone have any affordable options that would let me get VGA to the f-jack AND inject sound?  Im thinking R/F modulator but I cant seem to find one that takes a VGA signal.   I am asking on the board because I know there are much smarter people here than me so if anyone sees a pitfall I'm missing or has a suggestion on a better solution any advice is appreciated.


Thanks all!

The "F-jack" is nearly the worst source to put a signal to in the history of inputs. (next to the 300 ohm flat lead)

you will need to either:

get an "RF modulator" box and then attempt to convert your VGA signal to the input of the RF modulator box with another convertor box. DOWNSIDE: not cheap... probably won't look good.

or get a videocard that has S-video output and feed that signal to the RF modulator box equipped with an S-video input. DOWNSIDE: s-video enabled cards are pretty scarce now a days

or hack the TV to accept an RGB signal. DOWNSIDE: may not work without extensive support circuitry (sync separators or inverters etc.)

TV's are a dime a dozen these days. you could probably get a brand new 32 inch flatscreen with VGA/HDMI input for under $200...or just wait out for a throw away CRT tv or computer monitor with better inputs.
