Hacking a TV

[Hornpipe2]

I have a TV in my cab and it's old and takes composite only.  I'm also using a PCI card with a composite-out port to match.  Quality is awful (as one might imagine).

Now I have spare PCI cards with S-Video outputs... but no TV (that would fit) with SVideo in.  Here comes the ridiculous question of the day:  since I have decased my TV and I'm looking at the circuit board, can I hack an S-Video connector into this existing TV?  My thinking is, somewhere on the board the composite signal is being split into C/Y anyway, so I should be able to just tap into that with a new port and upgrade my video connection greatly for about $2 worth of parts.  Are there level issues to contend with?

As a followup, this is a hell of a hack:

(Add RGB interface directly to the guns of the TV)

I've read this several times over the years, and I don't think it's possible the way he's writing it.  I think he's wiring the RGB to the signal processor rather than the guns.

If you're going to that much trouble, perhaps you want to go all the way, and do straight RBG?

Open it up and look at the datasheet for all the chips in it, you may be lucky but if its all controlled by a microcontroller you may not be able to make it switch over.

IMO, its the time that everyones geting rid of their old tvs so go to the local used appliance store and see what they have for $10
