Query: Robbery Fake Bulb

I purchased this bulb thinking that I was getting a Sony bulb for my TV and was disappointed when I tried to turn on my TV and nothing changed. I got an error message stating that the newly purchased bulb had the same problem as the original Sony "Philips" bulb. I am really shocked that this was not the original Sony bulb as advertised. Now I have lost my money and my TV still does not work, that is why I am writing to warn other consumers to be careful of companies like this one who are trying to rob them with false advertisements.
