iMac low color quality after self repair

[commac]

I just opened up my old iMac to replace the optical drive and now my screen looks like this...

Notice the low quality color.

I have reconnected the 4 inverter cables, the LCD fan sensor and the data cable.

The screenshots are perfectly clear indicating a LCD issue. Hopefully something silly.

Any ideas? Thanks for any help,.

if it is still under warranty, put it back the way it was and take it into Apple and say WUTS WONG WITH MY MAC!!!!! I think that is the best solution anyway

You really think that that they won't know ?

OP, your LVDS cable might not be seated properly so I would reconnect that cable. If your screenshot is coming up properly, the issue is with the Display, LVDS Cable or logic board.

If I had to take a guess, you could have damaged the LVDS cable or the connector on the logic board side.

Well no wonder people are having so many screen issues with iMac... They keep breaking them open and upgrading when it wasn't really intended to...

In other words, commit fraud? They will most certainly notice the OP has opened the machine. User damage is not covered by any warranty.

I was able test another LVDS cable with no success. My theory now is that there was some static electricity damage to a chip on the LCD during teardown.
I'll ask Apple what they suggest and what they can offer but it will likely not be worth the price. The imac is out of warranty. Maybe I can find a used working LCD on eBay.

Removed.

Thanks for the info iMacC2D

In the end the problem wasnt even display related....

After the replacing the LCD with no results I swapped motherboard and voila.

Musta been the LVDS contact on the board or a short somewhere... A shame something probably small needed a full logic board replacement.

Hope the thread helps someone else one day.

How did you manage to get parts and fix it do fast? Did you get a quote from Apple as well?
