For me, a damaged panel is a housing or a matrix panel (electronics) and a damaged matrix is a matrix or a matrix panel when it comes to the proper use of names.
I also make an amateur from one palette of returns from the store, a working TV sometimes even 2-3 TVs from a dozen or so, and if there is a lack, I buy a damaged TV for pennies as I have an efficient matrix. The failure rate of TV in stores is sometimes quite high, about 5% breaks down even during delivery, if the matrix with a few pixels is not rubbing the casing, no accessories, flooding packages, etc. sell.
As you write antiquities, it's hard to get hold of, I rather try to only deal with new ones.
ps The attractiveness of the price is another matter, once I bought 3 matrices 32 inches for PLN 25 each only because they were from models from 6-7 years ago. The shipment was more expensive, but the replacement cost covered the entire purchase.
