iPad Air Won't Turn On, Error in DFU Mode :/

I recently acquired an Apple iPad Air 1, which the previous owner had mentioned would turn on to the apple logo screen, though the screen appeared to be 'glitched', as pictured, and would not load further.

However, upon receipt (by mail) the iPad would not turn on at all. I was able to get it into DFU mode and start the recovery thru iTunes, but it hung on 'Waiting for iPad', and gave an error (4005) after about 10-20 minutes.

iPad itself looks to be in good condition, though I haven't opened it (hesitant to do that if it's not completely necessary).

Any thoughts?

I have never seen that pattern before. It could be just a bad LCD but then the rest of the iPad would work normally. The Error 4005 makes it look more like a logic board issue (NAND, SDRAM or Power). Ideally, the logic board needs to be looked at by an experienced micro-solderer to determine if this is fixable or not.
