Buy a TV and crack the LCD, the new LCD will cost 90% of the price, and then you need to throw in labor. Let's say $100. That'll cover an hour of their time and the shops time because they first have to verify the model, talk to a vendor, get it shipped, then install it and deal with the drop off holding contacting you for pick up and payment processing. After paying the workers, maybe they made $50 off that repair if they are always busy. If a part is DOA, more costs. Total it all up and realize you spent $550 to repair a TV that is on sale with a 1 year warranty for $499 at Walmart with no waiting.
Assembly lines make things cheap, especially if the labor is cheap
