How to use SCART for our hobby
Em:
Hi Zeb,
thanks for the info. I think I need to get a TV that's slightly less old then! I'm not sure if there's a v-hold knob inside the set and I don't really want to open it up. I did try getting into the service menus on it a few times to see if there were some settings I could adjust, but entering the sequence of buttons on the remote causes the whole TV to freeze. It wont even turn on. Have to disconnect the power for a minute or so to let it recover!
Thanks again.
Em.

hello everyone
trying to connect a vga to scart on my hantarex CT EQ/3 28" : http://www.hantarex.be/BtoB/pdf/cteq3.pdf
i have made a cable without the 12v : : http://www.alvarezeninternet.com/mamescart/scartuk.jpg
know i am having broblems with the colors....on the back of monitor there is a switch from video to rgb to off , and when i switch between rgb and of i get a spit second good collors ??? alsow wen i tik the ground cabels from vga to some of the pins on the scart the same thing happens .

I thiink the reason why your TV doesn't work so well is because you don't have any RGB switching signal @ SCART pin 18 16.
BTW, to be consistent w/ earlier posts, in this thread I am referring to this SCART pinout chart:
http://pinouts.ru/Home/Scart_pinout.shtml
In earlier parts of this thread, you can find instructions on various ways to get the ~ 1-3 volts you need to this pin.
The easiest way may be: cut a small piece of wire ~ 3-4cm long (about 1.5 inches) and make a 'bridge' from pin 20 (sync) to pin 18 16. But this doesn't work for all TVs.
If your cable has the right wires, and you have an ATI video card (inc ArcadeVGA) or other card, you can tap into the 5v on VGA pin 9. Put a 100ohm resistor on the end of the 5v wire (VGA pin 9 ) and attach it to pin 18 16.
Best way is to hack a standard molex power supply cable (the big one with 4 wires: yellow, black, black, red). You need the red wire (5v) and one black wire (it doesn't matter which one). Extend the cable (ie solder some wires on) and feed the ends into your SCART header. Put 100 ohm resistor on the 5v red wire (now it is 2v), and attach to SCART pin 18 16. Attach the black ground wire to pin 16 18.
Bet you this works!

wil Try tis out and report back on the forum if it works Zebidee :)
i have vga 13 to scart 20 and vga 14 to scart 18 and a bridge from 20 to 18 , is this good ?

No. you need to twist VGA 13+14 together and attach to SCART 20. The bridge from SCART 20 to 18 is good.
The bridge should be from SCART 20 -> 16
If that 'bridge' doesn't work well, you should try one of the 5v + 100ohm resistor methods.
