I did a hard drive replacement on this iMac about a month ago. Have not used it for about a month. Today when I try to boot it up it beeps like it has no or bad RAM. I tried new RAM sticks to no avail, still beeping like it has bad RAM.
While removing the screen to replace the HDD, the vertical sync cable came out damaged. I did my best to put it back in. Would a damaged vertical sync cable be causing this?
Is this a good question?

I actually just solved my problem. I looted a display from an identical iMac that had suffered a fall and broke it’s foot (ouch!) and plugged it into the problematic iMac and it booted just fine. It was indeed the cable after all. @my64pro @mayer thanks for stopping by!

It could be possible that this is why it does not work,the computer maybe detects that the LCD is not connected due to the cable being damaged. I recommend replacing it and see if that fixes the problem.

I don’t think the vertical sync cable itself is replaceable. I think I am going to have to replace the entire display which is not economically worth it.
You can replace the cable to the display,they sell the cables online.
Where are these cables sold and how do I replace them?
Looking on google,the price of these are very cheap
@my64pro Thanks for the link, however I have solved my problem. Thanks for stopping by anyways!

Is there a pattern to the beeps? Did you address the hard drive thermal issue if you changed brands of hard drives?
What are the diagnostic LEDS telling you?
