@shadyahmed - Sorry guy your issue is a bad display! Not a logic board issue.
The bars are caused by a broken LCD screen. In fact, I think I can see the point of contact and a crack in the right midpoint. Did the system fall over or something thrown at it? Or did it get shipped to you and got damaged then?
Here’s the IFIXIT guide you’ll need to follow: Sostituzione Display nell'iMac Intel da 21,5" EMC 2544 and here’s the needed part: TheBookYard UK - iMac 21.5" LCD Panel & Front Glass Assembly - Grade-C, Apple P/N 661-7109 and you’ll need this toolkit and tapes [prodotto collegato mancante o disabilitato: IF173-005] Make sure you follow the IFIXIT guide don’t jump ahead as the process of taking off the display as you don’t want fragments falling off.
Questa risposta è stata utile?
Thank u Very much :)
my imac screen fall and screen glass get damage but it was fine untill i change it with new one , then it become like this from few days , and i don't know this is only screen issue or something new , but i will try to change Glass screen and see if it works
Sounds like it was damaged before hand. You can also damage it in the take off process if one doesn't use the proper tools and technique as outlined in the guide.
So it could be both! The person who sold you the display didn't use the proper tool and in shipment to you it get poked cracking the display.
