amiga 1200 on tv crt

[b41d3r]

Hi all,
After a while playing with emulation and programs from TOSEC, I decided to step further towards Amiga "way of life".
I bought recently an amiga 1200 from a friend.
It seemed pretty well with a cdrom, a hard disk, a squirel scsi, a joystick, a faster card and a second floppy drive.
But as I got it yesterday, I tested it on my old crt tv from the 90's. I knew my colleague who sold it to me could not obtain a decent display with his tv's.
I must say I don't get any better result, I connect the amiga thanks to a scart plug but all I get is some white stripes scrolling on a black screen.
Do you know if it's fixable or my amiga is only screwed ?
I believed that with an old crt tv like mine, things would have gone straight.:angry:

Hi,

I don't know if I can get a modulator but I tried with a S video and 2 rca and same result.
Is it possible that it's only a problem of frequency ? That would explain the scrolling, no ?
Is the amiga susceptible to the kind of TV ?
I think I've read somewhere that all TVs would not fit, or is it only true for LCD TV ?
I'm a little puzzled ...

Yiha ! :roflmao:
I got it thanks to your advice framiga and stefcep2!!
I selected the right display mode, and bingo !!
Now I just have to resize the display because the window frame oversize the screen.
I really owe you one. I was close to surrender and actually in despair !
You don't know the good you did to me !:)

If you're still available, do you know how to make the change permanent and to resize the display ?
Because, each time I boot I have to reenter the display option at boot  time.
Thank you again !
