Convert RGBs to VGA

post #1 of 2
Thread Starter 
Hello all,

I wish to convert from RGB tv video (with one, separate sync) to VGA or anything "contemporay and off-the-shelf".

I appreciate your time and assistance. I fear I cannot offer enough detail, but I figured I would take a chance and seek out sharper minds. I apologize upfront for my ignorance.

I support a chip placement machine that utilizes a 14" tv monitor (which is now obsolete). This monitor accepts R, G, B and S inputs from a proprietary video card. The vendor (based out of Eindhoven, Holland) no longer supports this model and cannot offer any technical help. Out of 6 tv monitors, 5 are no longer working. The vendor's solution is to purchase a JVS monitor for $1500. I hope I can discover a cheaper solution!

ORIGINAL TV MONITOR SETUP:
Output (from machine video card): Discrete R, G, B, S with SMB connectors
Input (to obsolete tv monitor): 9-pin D-shell

VENDOR RECOMMENDATION TO REPLACE OBSOLETE TV MONITOR: utilize JVC 15" color, model TM-H150CG
Output (from machine video card): SMB connector on G output only
Input (to JVC tv monitor): SMB to BNC adapter to "Video Line A IN".

The replacement monitor is a JVC 15" color monitor, model TM-H150CG.

I did buy one, and it does work. However, I need to replace 4 monitors immediately and stock one spare for storage. Hopefully, one may be able to recommend conversion hardware or a different, less expensive tv monitor.

I hope I can find a solution better than a $1500, 15" tv!

Again, thanks for your help!!!

The TM-H150CG is a 15khz video monitor, so what your "vintage" workstation deliver is 15khz RGBs. Interesting though that the new monitor works with just the G line which means the color signals aren't pure, but you basically have R, B, Gs, S (Gs = Green with Sync on Green).

If top quality isn't this important, you run a very good chance that the very same connection, which works on the new 15" monitor, works on every TV you can buy, no matter if CRT or LCD. You should be able to try this on any TV you have on hand. Just use a BNC to RCA adapter ($1) and plug it into the yellow RCA video connection as this is essentially the same as the BNC Line Video input on the 15" JVC.

If you want a more sophisticated solution, you can look for RGBs to VGA converters (Google for Scart to VGA) which are about $100 a piece or RGBs (Scart) to component converters which are about $50 a piece.

I don't see much of a problem and definitely no need to shell out $1500 each for a bunch of "old" CRTs.
