iPhone 5 boot loop with brushes in different colors, vertical, horizon

Hi,

i have search on this Forum and look for answer but i have nothing found.

After a crash on the ground my iphone is in a boot loop with very strange effect.

The iphone was not detected on itunes. I try the Recovery Mode and DFU Mode. Nothing helps.

Please, look at the pictures:

First of all normal Boot bei press the power button:

Normal boot

Then one second after the normal screen with apple logo you see this:

special effect

special effect

I hope you can help me but I think it is an hardware error. Can you fix it?

Best regards Benny
