Minimig Scart Lead
(I posted this question to Amigakit but they havn't got back to me yet, so maybe the Amiga Community can help until they do )
The scart lead I received for the minimig dosn't seem to work properly, I tried it on two televisions and I could see the kick 1.3 sign (kinda) but it was very garbled and not properly visible, black & white lines mostly. Thankfully my flatscreen monitor works with the minimig with a regular vga lead My question is, is this just the minimig not compatible with the telelvisions I own or is the lead bad? I noticed that if you compair the vga end of the minimig scart lead to my regular monitor vga lead theres a pin missing on the vga end of the minimig scart lead. 15 pins on a regular vga lead 14 pins on the vga end of the minimig scart lead 2nd row down 4th pin is missing! Is this supposed to be missing? Is this possibly why it dosnt work correctly? It would be easy to compair this to my other minimig, but I'm currently lending it out to a friend at the moment. |

Pin 9 is just a key, it's not used http://pinouts.ru/Video/VGA15_pinout.shtml

You should post to our Support area for help with products.
All our Minimig Scart cables are thoroughly tested. Check your 15Khz / 31.5Khz jumper on your Minimig motherboard. Sounds like a frequency problem. |

Its currently set on 31khz, which works ok with my 19" Dell widescreen monitor with a vga lead, when playing games the picture is a bit off center but this used to happen on real Amigas didnt it? (I tested it on winuae on A500 quickstart mode and its off center too, except in winuae it can be adjusted)
If I change it to 15khz that would make it work on my tv but not on the monitor correct? I'm a bit dubious when changing the jumper as I read on the Minimig forum, someone said (I think it was jakub I could be wrong) 'don't mess with the jumpers, you could fry your board Last edited by Kitty; 04 November 2009 at 17:08. |

TVs generally use 15Khz modes.

I am sure it is fine to change this jumper when the power is off. |

Thanks for that info alexh but I just found a pc vga input I didnt know was there on my Panasonic 32" HD TV, and it works awesome, I can even adjust the screen Vertical/Horizontal in the tv settings, now I dont even need to change the jumpers!
Edit Would scart output be any better picture quality? vga on the tv looks pretty damn clear anyway. |

Try it and find out. I dunno the MiniMig's AMBER specifications nor it's TV interlace capability. |

guess I will have to stick to the vga lead, scart lead was a bit of a waste of money |

It is possible that TV mode has been removed from later versions of MiniMig FPGA binary?

She is using a Minimig to scart lead. EDIT:- Which scart socket are you using on your Panasonic? Reason I ask is not all tv's accept RGB on all scarts. Panasonics normally only accept it on AV1, check the manual, to see which accepts RGB. I know my Samsung only accepts RGB on Scart 1, 2 and 3 is non RGB.

I'm using the last minimig1.bin from minimig_build_YQ090421.zip, thats the latest version before you need an arm controller for any minimig1.bin after that release, if that makes any sense?
Defintley get black and white on small tv and just black screen on hdtv with scart, its not a big deal as I can just use the vga lead, but strange all the same as was tested for 2 days before posting out. Possible lead isnt compatible with some makes of televisions? The hd tv is panasonic 1080p hd although I'm using the scart 2 output and the small tv is matsui crt with one scart port on the back.

The firmware has no bearing on this: you need to plug the SCART lead into a SCART (RGB enabled) socket on your TV with the correct frequency (usually 15Khz).
If you do not put it into the right SCART socket, you will get a blank display. If you use the wrong frequency you will get a garbled corruped display. |

ok I'll try it on scart 1 input, one sec..
Edit Nope exactly the same. On 31khz the scart lead shows garbled on both tvs on all scart sockets On 15khz the scart lead shows black screen on both scarts on hdtv and black & white but works on small tv. Last edited by Kitty; 04 November 2009 at 19:09. |

You sure your setting RGB mode on your panasonic, as it doesnt automatically switch it to RGB.

On the settings AV2 is just AV2 or Svideo Theres no option to set it to VGA from the on screen settings, so I'm assuming that VGA on both scart inputs (AV1 & AV2 ) should be automatic, although I've yet to find a setting to prove this otherwise .. |
