Crashing boot looping lines colours bad bad bad tablet

I have a tab s 8.4 sm t705 I was running kk rom I flashed LP rom and now it boot loops. The images I have attached is when it crashes and reboots. For some reason it is showing all lines and either blue or red screen sometimes.
I tried to flash twrp and it will not do it. I am at my wits end what to do any help would be a saviour

Cheers
