Repairing a 2017 27" glass screen - worth it?

[madeirabhoy]

Just realised my iMac's screen has a noticeable long scratch on it. unfortunately the table it was on broke and it must have hit something on the way down. its only the glass, the screen behind it works fine, it just looks like a big dirty mark.

is it difficult or expensive to repair? living on a small island there's only one apple repair centre which is run by a third party electronics company. its a pain to drag it down there so I don't want to if its going to cost €500.

if I bought one second hand am I likely to be able to replace it?

The glass on a 2017 screen is inseparable from the panel so a new screen is needed.
The screen panel is glued to the back case, so requires extreme care to separate it, with the right tools.
A new screen is likely to be more than €300 (maybe a lot more), and a repair shop will want a fee for the hours of work it will take.

It can be done DIY following this guide and a used screen taken from a 2017 iMac (models from other years are different). They can sometimes be found on eBay, or a complete non-functioning iMac with a good screen.

Probably a new screen is easier to find, and more likely to come in a proper box for shipping such a fragile item.
But there are refurbished screens on sale (broken glass 'repaired' in China) which are sometimes not good quality, so caution is needed.

In part the scarcity of cheap screen panels is because people are buying them to turn them into 5K monitors to use with Apple Silicon Macs. This requires removing all the internal electronics and buying a new video driver board from China to power the screen.

Cheers. Think I’ll leave it then. It’s not my main machine and if I have a plain black screen and night mode I can’t see it.
