I had a duff main board that I copied the flash ic however from the Polaroid SSDV2311-I1-D0 same screen as yours I am not sure if it was faulty or the main board was faulty. It turned on displayed Polaroid logo and then powered down! I would have taken new dump from replacement board however the TV was sold before I had a chance to read it out from the good working board.
I guess worth a try.
Let me know how it goes.
