I have the same problem with mine. Screen was gray but I had sound. Nothing I tried worked. I bought a new TV and the Ilo is sitting in the junk room till I find a solution or get the ambition to take it to a shop to get checked out.

The main power supply will be the first place to check. You should have at least the standby 5vdc, which is used for the main board, when the power switch is activated, the main board will send out the signal to turn on the main power supply sections to power up the rest of the set. Look for simple thing like blown fuse or bad capacitors. Learn about what bad capacitors can do. http://en.wikipedia.org/wiki/Capacitor_plague
It looks like the power supply failed on your TV. If the LED is solid red or green, it could be some leaky or dry capacitors but if the LED is blinking, the failure is more complicated to repair.
I service these power supplies. If you need more info you can send me an email to email@example.com
There is a capacitor that is out. It is a 470uf 25v. When you open the back and look at the power board there are three group together. It should be right there. You will be able to tell if the capactor top is bubbled replace it. It should be completely flat.
