The display started showing something like snowflakes

Hi guys,

I have followed the exact steps of reinstalling the HD in my iMac Intel 20" EMC 2266. However, as soon as I put all parts back in, connected all necessary cables and turned on the iMac, the LCD display started displaying something like snowflakes and lines all of the time. It looks like and old time TV when your antenna is not fixed and you see the picture through snowflakes. Does anyone know how to fix that?

Thank you very much in advance.

Best regards,

Petar

The new hard drive would not do this. Please go back to the repair guide and check all the connections you touched. Check the connect on the display data cable.

I have checked all cables thoroughly. The display data cable is also connected to the logic board as well as to the display. Still the same. Is it possible that the cable is somehow corrupted?

Could be, visually check it for damage.
