I think I smoked a capacitor on my IN72 projector but I can't seem to get the case open. There is a rectangular slot on the back of the unit with a small lock printed next to it, but I can't seem to find a way to open it. I have removed the screws on both sides, so I believe its just a piece of plastic stopping me.....Help Anyone!!!!

Someone please post the values for C517 capacitor next time you open your IN72/IN74 or IN76.

I've completely disassembled this projector and it isn't hard. Once you have removed all screws from the bottom of the unit, the two grey ovals on the sides will slide to one side and then pull out. Push on the grey pieces to slide them first, and then pull. Once those are out the two sides of the projector will come apart. Pay careful attention to where the screws go and it will be pretty clear from that point on.
