screen problem

[krekacska]

So today morning I locked my iPhone 5 out, and I saw on my screen a lot of thin and small red,green,blue -so colored- lines and my screen was vibrating too. The lines aren't there always, they are there for 1-2 mins, and after everything became ok. I did a screenshot but I can't see them on it.
Is it LCD or logic borad problem?
Could I fix it?
(sadly my warranty ended 20 days ago..)

Thank you for your help!

If your screenshot doesn't show the issue, its likely a problem with the physical LCD. Those lines can appear if you've dropped the phone or put a lot of pressure on the LCD by mistake..

Is it possible that I dropped the phone 1 moths ago and it come out now?

Can I fix it with a new LDC?

If you did drop the phone recently, its possible that the cable may have come loose a little initially and perhaps with the normal jostling of the phone it got loose enough to now show some artifacts..

You can follow the iFixIt iPhone 5 Teardown to open up the iPhone. Once you have it open, ensure that the digitizer (what's the LCD component is called) cable is nice and secure.

You can also look at the guide to figure out how to replace the LCD if it comes down to that..
