Are pictures 2-4 the results of disassembling and reassembling the reader three times, or did the screen get progressively worse?
I still think it has to do with the ribbon cable, but I fear I don't have a solution for you. It looks and seems to me that the cable may perhaps have become damaged, in which case I'm not sure if anything can be done. At least I think that's a lot more likely than the screen itself having been damaged by the reassembly after the battery change.
If no solution is found and you'd rather not buy a new reader, or at least not without exploring further options, I would see if there isn't an electronics repair shop near you and check if they can do something to fix it. Hopefully they can and hopefully it won't cost all that much.
