imac late 2009 screen display bug

Hello everyone

I have an imac late 2009 under OSX 10.9.5

yesterday I decided to change the computer's disk, so I replaced the 500GB HDD with a 1TB SSD

by following this tutorial

https://www.youtube.com/watch?v=oKWaLcD0cb4&ab_channel=RickMakes

I made a clone of the HDD, I reassembled the computer without putting the glass on the screen and I only put two screws on the 8 of the screen. I started, it works,

as it works, I stopped the computer, put the missing screws and put the window back on,

and there I have a display bug, the one you can see in the photos

any idea?

I do not think of a contact failure because the computer was working

the problem will stop by putting the HDD back?

regards

Welcome to the Apple Support Communities.

This is a hardware issue due to accidental damage. Unfortunately, due to the age of the Mac, there is nothing you can do. Apple or an Apple Authorized Service Provider cannot service it since it is obsolete: Obtaining service for your Apple product after an expired warranty - Apple Support.

Unfortunately, it's time to replace this Mac.

Also, do not use CCleaner. Mac computers do not need any sort of anti-virus, cleaners, VPNs, etc. The only thing they are good at is creating false marketing promises and taking consumers' money. They are all scams. In fact, anti-virus and other cleaners cause performance issues, security issues, and make macOS appear buggy. Your Mac is far worse with these types of Apps installed. Mac computers have protection built-in, which is the best protection for your Mac. For specifics on macOS Security, see: macOS - Security - Apple and Protecting against malware in macOS - Apple Support. Mac computers also have built-in storage recommendations: Optimize storage space on your Mac - Apple Support. You can even use the built-in macOS Firewall: Block connections to your Mac with a firewall - Apple Support. Other than that, all you should do is restart your Mac approximately once a week and keep macOS up to date: Update macOS on Mac - Apple Support.

+1 on not using ANY "cleaning" app. Macs, cat-like, clean themselves automatically and have for 20 years. They even defrag without your have to worry about it.

All the third-party stuff does is interfere with some very elegant system programming you paid Apple to develop. A further concern is that most "cleaner" apps are ported from Windows to Mac and can have a nasty tendency to identify critical Mac system files as unneeded and delete them. I see no Mac expertise in that.

the problem will stop by putting the HDD back?

Depends. If you COPIED the old drive to the SSD, it may help to CLONE the drive instead. Cloning moves everything—copying can miss stuff. I use Carbon Copy Cloner. Get is ONLY from the developers site: https://bombich.com

What make SSD did you install? Best Mac resuls are with Crucial's MX series and Other World Computing drives. All otehr tend to fall short.

However, this seems to me as it does Jack—a video hardware issue. If this is a 27-inch model, you could have a video card that decided to fail at the same time you went inside to do the drive changeover. Both the 2009 and 2012 27-inch models were apparently hard on video cards. My 2010 27-inch started showing small areas of intermittent pixilation much like your third image long before its video card completely failed.
