Anemos.

after i saw your pic of this in action:

i noticed your TV is pretty much a non-widescreen version of mine.

Alas, I have been unable to get my "copy" of your cable to work so far! ... i am going to have a couple more attempts, but scart plugs really annoy me, and I am getting frustrated with my efforts and the amount of time it's taking me to achieve nothing!

If it comes to it, could you build one of these to sell me?

[Anemos]

first, i dot test this cable on any wide TV,s ,only on LG LCD TV flatron M1717A(in not wide) ,and normal CRT TV 21" working both good.
dunno if working on wide TV yet..
I can make one cable to send to you (free)
but i have not original 23 pin (plug video Amiga) only 25 pin printer porting and i cut it to 23pin.
like this :



if you like i can make one for you

hi Anemos,

I'd certainly like to give it a try, knowing that it is at least tested with an amiga on an LG LCD screen.

I wont take it free though, postage costs covered at least!

thank you Anemos, and i'll let you know. I have one more plan to try first!

He is a great guy, .

hey FOL whats up? we lost you..

@Horace.. i have also Scart cable from amigakit,this working also fine on my Tv,s.
maybe your problem is the wide! my LCD TV is NOT wide!
so.. im not sure for this: try to change the 1Kohm resistor with a bigger (like 2Kohm)  on 22 pin amiga to 16pin scart.
maybe needed droping the voltage there to working the wide mode..

Edit: this diagram for ZX+3 using only 68ohm resistor to 16pin scart on 12V! maybe needed smaller resistor and not biger for WIDE!

im using also this cable whit out problem on my TV,s.
Dunno.. but careful the 12V in wrong place can destroy the scart board on your TV!

Update: look the edit in the last post..

I cant see why it would make a difference between wide and 4:3, 12 volt is 12 volt.
Set will detect it no matter, infact, you could cut the 12 volt pin and switch it manually.

12 volt is not needed, as you can manually select AV1 or AV2 (scart sockets).
The 12 volt, only tells the TV what AV / EXT to switch to.

[Anemos]

im not sure.. maybe this is important for wide:
   

SWTCH     Audio/RGB switch / 16:9     0-2 V=TV, 5-8 V=WideScreen, 9.5-12 V=AV Mode

on pinout scart : http://pinouts.ws/scart-pinout.html

You missed my point, you could cut that pin and it would still work.

Those voltages have to be a mistake, its only 1 voltage and thats 12 volts.
Its simply there to switch the TV to AV mode.

Anemos, simple question, does your RGB to Scart turn your TV / LCD to AV mode?

[Hungry Horace]

Amiga RGB outputs seem to be very sensitive.

FOL, i am not sure it would still work.

the 12V thing was missing from my (old) cable, which only displayed the screen as 'white' ... i know you said it's for switching FOL, but its possible newer TV's use this to check if it should bother pulling a signal through?

The one i tried to make like Anemos', flicked to white, and -then- went black with "no signal" displayed. I think the only different with the 12v line being connected with the resistor on it.



i would guess the widescreen thing makes no difference though Anemos. everything else from the days of non-widescreen has worked fine on widescreen TVs i've had! Cant be sure though.


no one in this thread can state any of these matters as fact imho, until working wirings / combinations have been tested.

@Fol, yes on AV mode.

@Horace you can check also that diagrams..

It is FACT, you dont need the 12Volt switching signal on an scart cable.

I have worked with different type of problems relating to scart connections between equipment and having 12 Volts makes no difference to operation apart from switching the TV to an AV channel.

Even with newer TV's its used for switching to AV Channel. Some sets use some other unused pins to transfer data, i.e. Sony's smart link. The Amiga however would never use the smart link pins.

Besides, another FACT, newer TV's detect the Video Signal and do it that way. Maybe it doesnt like the signal voltage. I know for a FACT my Samsung, skips AV's that have no signal. i.e. nothing in my scart connections, then AV1 and 2 are missing off my selection menu.

Anemos, your links are confusing, cause they are all different.

Aaa... i just want to Horace for others choice.
im on new schematics Amiga > Scart.. hope next days have answer ..

I know, im just interested. Cause same thing happened to me, and it would only work on 1080s monitor.
On TV is was white, mine did work on the TV before.
My wife was playing Pinball Fantasies, when after 30 mins the screen went white, and it never worked again. Always stayed white.
