After repair iMac fans spin but no display and no chime.
I replaced the HDD with an SSD (formatted) reassembled everything in its bare state, it turned on and chimed. I fully reassembled it, fans ramped up but nothing on the screen. Checked all connections. Reseated GPU and CPU. Reset SMC. No beeps. Nothing. If you’re curious, there were 2 lights on, one indicating that power was connecting, the other indicating it was powered on.
Please help!
Is this a good question?
Found out that the 3rd light means that the computer is communicating with the GPU which the 3rd light is not on. I’m looking into buying a new GPU for it so I’ll see if that fixes anything.

After a motherboard swap and a GPU swap, the iMac still doesn't turn on, it just does what it did earlier, fans spin, no chime, nothing showing on screen.
