Welcome to EAB
My girlfriend's Dad had to purchase a Scart to HDMI adapter in order to connect an old VHS & DVD player to a new Panasonic TV.
Hopefully it should also work with your Amiga (but obviously can tell you 100%). Luckily they are not too expensive so you can give one a try.
Just Google "Scart to HDMI" and there's loads of different options e.g. http://www.buymystuff.co.uk/panasoni...d-televisions/
