My daughter sprayed fabreeze on our 60' sony flatscreen and now I cannot get it to power on. She sprayed a few spritzes on the screen and after a minute or two it shut off and will not turn back on.

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

Does the power light stay on? If so, you have an inverter problem. If the power light goes off, you have a power supply problem.
