Hi
my late 2012 iMAC 27 as it boots up I get the screen covered in multi coloured bars and after boot up the screen flickers
I is 100% ok when running on an external monitor
I this a failed graphics card or the screen itself
PS where is the graphics card I have the screen panel off and can’t see anything obvious
Thanks

Sadly this sounds like you have a bad display assembly. This can happen when the wrong tools are used to remove the display. Here’s the proper tool you need: iMac Opening Wheel and i recommend getting two sets of these Plastic Cards. As you’ll need new adhesive strips you might as well get the kit [prodotto collegato mancante o disabilitato: IF174-005] which comes with the cutter wheel. And lastly here’s the needed part: 27” iMac Display Assembly (used) Apple P/N 661-7169 The new ones do seem to be in short supply.
Here’s the guide to put it in Sostituzione schermo iMac Intel 27" EMC 2546

Hi
This iMAC has never been opened until I did it yesterday
I bought the recommended tools on line
I don’t agree with you on this one
