Comment Sony history (Score 1) 125
Sony has a history of actions like this.
I remember when people would actually repair televisions.
But Sony wanted it all and weren't interested in sharing.
They would erase the generic 7400 series part number and apply a propriety part number to a generic IC.
So, to fix your Sony TV, you were forced to buy the part from Sony so a generic 35 cent 74ls04 IC would cost $8.95.
They never changed.
