Are we obliged to change the polarizer film when refurbishing a lcd
When I searched online to see how to refurbish LCD displays, a lot of the videos are showing how to remove the polariser and how to add a new one. but some other one don't change the polariser, instead, they just clean it and place the LCD in a mould and add LOCA glue and place the new glass screen on top and put the UV light on top.
So my question is, can we save money by just cleaning the old polariser ?
Is this a good question?
