Amiga to Scart TV cable diagram (by Anemos)

have you seen this one Anemos?

I dont quite understand it myself...

Very interesting Horace.

[Anemos]

so.. using [Small Signal Transistors (NPN)] resistors and one capacitor 10?f,
dunno.. must be first found this transistor to test..

@FOL,  im not sure where is the ground line ?? on the ends sides of resistors? (look the attached photo)
also.. i have the C547C transistor is the same to BC547 ? im not sure!
i have also:
BC548 C
BC559B
C548B

dam! what is it the BC547 at all? (Amplifier,planar,signal transistor?) aaaaa...

1     BC547    NPN general purpose transistors    Philips
2    BC547    NPN Epitaxial Silicon Transistor    Fairchild Semiconductor
3    BC547    General Purpose Transistor    Korea Electronics (KEC)
4    BC547    Small Signal Transistors (NPN)    Vishay
5    BC547    Small Signal Transistors (NPN)    General Semiconductor
6    BC547    NPN Silicon Epitaxial Planar Transistor    Honey Technology
7    BC547    NPN SILICON AF SMALL SIGNAL TRANSISTORS    Micro Electronics
8    BC547    NPN Silicon Amplifier Transistor 625mW    Micro Commercial Components
9    BC547    Si-Epitaxial PlanarTransistors    Diotec Elektronische
10    BC547    Amplifier Transistors(NPN Silicon)    ON Semiconductor

All edited post in the last post plz..  /\

It is actually drawn based on an incorrect assumption. You can connect CSYNC directly to the SCART connector and it will work. The circuit in there is because the person who drew the schematic thought that CSYNC is TTL level like H and VSYNC are.

So just disregard it and just hook it up.

Sounds reasonable, .

right... just to clear one thing up, i bought a PS1/2/3 -> scart-RGB connector for £2 from ebay, and have just tested it.

It seems this works fine on my LGTV, so it has to be a matter of getting the correct wire configuration in order to get my Amiga to work, and is not a case of non-support by my TV. (exactly what KG told me, but many people were 'demanding' i test it with something)

[Anemos]

so.. this diagram: http://eab.abime.net/attachment.php?attachmentid=16635&d=1211291464
using analog lines and composite from amiga, TTL is digital signal ,dont using that,also Vertical and Horizon ,.. i dont see somthing wrong before to test..
the transistor maybe is only for signal reinforcing on composite..
@Horace check again my diagram and if is right the sides of plugs.
test your amiga scart on other TV smaller CRT ect.. (i hope the problem it does not come from your amiga)

As jope said (he posted it on EAB), the circuit is not needed.

My original cable worked on CRT (badly), but not LCD. It was missing some wires though compared to yours, and others.I havent had time to test other wiring combos, but the one i wired the same as yours, gave only a 'black' screen on the LCD (not tested on CRT)

(i hope the problem it does not come from your amiga)

i've tested using 3 amigas. A500, A600, A1200. all of which have the same result.

[Anemos]

ok,do you know your scart diagram of this LCD TV?
check your manual perhaps is there.. and post it here.
some Tv,s has deferent scart lines,and some has clear RGB,some others not original RGB,just composite signal..
 

[Anemos]

fixed diagram like as first post..
My fault multimeter measuring after closing the connectors..
sorry for this..
