Internal display not being recognised after battery replacement a1543
Hi there. I recently replaced the battery in my macbook a1543 & now the internal display doesn't work and is not recognised in the displays part of system settings. External works fine
Very strange considering I didn't disconnect or touch the screen during the battery repair process.
Any ideas on what's causing this or what will better allow me to debug the situation.
Current hypothesis is maybe the ribbon cable broke internally, but i know nothing lol
