Screen only only shows stripes!
My iMac screen suddenly started showing stripes only. It starts up normally, but I can't see anything, Everything works fine but the screen itself. All it's displaying is just stripes vertical and horizontal. The iMac never fell, nothing ever hit it.
I napped leaving music on the computer, after waking up I found the screen totally messed up.
I wonder if I over used it. I tried everything I can rebooting and so on, nothing works.
Now I have no idea what to do! I'm a graphic designer and I work with it a lot. It never showed any malfunction for two years until now,
I also have no warranty left and I don't trust third parties at all here in Morocco, most are scams.
Hope someone can help me do something .

See step #56 of this guide to see the GPU: Changement carte mère iMac Intel 27" EMC 2639
If this were to come into my shop, I would use a hot air gun and reflow the GPU first. If you do decide to try to have it fixed, look for an old tech who knows his stuff and has a hot air station, like this one: Soldering Rework Station Hot Air Gun: http://www.newegg.com/Product/Product.as...
Explain what you want done so that he knows you know your stuff. The bill for the attempt (if you;ve done the teardown should be under $50.
OR buy the machine yourself, do some study using videos by Jessa, like this one: https://www.youtube.com/watch?v=A0OiT9e_...
and videos by Louis Rossman and do it yourself!
