Black screen after HDD replacement
Hi,
after my 1GB Seagate hard drive died, I replaced it with a 2GB Seagate hybrid. While I had my 27" late 2009 iMac open, I also replaced the optical drive with an SSD, as per the instructions posted on iFixIt. The whole thing was quite easy to do. However, after the upgrade my computer turns on -- there's no start-up chime but the fan comes on -- but the screen just stays blank.
I went in there again and checked that all four cables that connect to the screen were properly plugged in. I can see the two installed drives in FW target disk mode. But the screen stays black.
Any suggestions would be greatly appreciated.
Many thanks,
TKV
