Hi all,

here's my contribution to SAMSUNG CB5079T CRT owners wanting to set the TV for MAME - SCART/RGB

Hi Blasteroo,

In my new build I'm using a xbox and a crt tv. via Scart/RGB.
But I have always push some buttons to see the xbox  srceen.  :banghead:

Is that the same thing u have to do when you start your game and tv up or is there a better solution to it?

Previous build where with pc and tft and startup directly in mala...
I don't know if that's the case with xbox CoinOps5, I'm new to this setup  ::)

Thanks and Greetings

Hi Superfrog,

Thanks for the input.

On this setup I'm using a radeon 9700 card and soft 15khz that outputs to crt tv via RGB= vga => scart.
When I turn the cab on (pc + tv) the tv is immediately fed with the video signal and automatically switchs to RGB channel by adding 12 volts to scart pin 8.
The 12 volts I get from my pc power supply, (via molex connector - yellow wire) directly to scart connector.
The red wire (5 volts) from the power supply also triggers the rgb channel, with Samsung's CB 5079T.
Other tv sets may not accept 5 volts to trigger rgb (my Sony trinitron sometimes doesn't).

Here's how to get RGB triggering via scart so you don't have to use the remote control (many posts and schematics available on the subject):

I got my hands on a Samsung CB-5079T. Using the original remote I was able to enter service menu following your instructions. But Im fine with the overall image, so I won't be tweking too much. I just want to know where on all this settings are the Horizontal, and the vertical adjust. I just want to move the image a little to the right, and up to be center. Anyone knows where is, or have a guess looking to this image?

Edit: Ok, I was able to find out on a service manuel of this model. Here it is attached if someone got the same doubt
