The tv won't turn on. I thought it was the fuse but when i replaced it, nothing happened. When i give the tv power 3 or 4 little green lights inside the tv come on, then a red on flash on the off.

Hit the front of the tv near the blinking light... give it a good rap or two. See if this helps. Helped mine. I had the same problem and the tech who came out to the house told me that it would work and it did! I could hardly believe it but it worked.
there is a problem with the power supply. most likely too much ripple that is ac leaking into the dc. I have seen the power supply repaired but it is not always possible. If there is an obvious swelled capacitor on the power supply that can be replaced this will be the best bet for repair. If there is nothing visually obvious then it gets a little harder since you won't really know which component is not working, the tv shuts down on a protection circuit so if the power supply can be repaired and the voltage "cleaned up" then the tv could work again. I have also seen replacement power supplys sold.
Sounds like a power supply issue to me. Did you check the 1.5A fuse and see if its still intact? Check it with a multimeter and measure the resistance. If it reads a very high value then its probably blown. The fuse is located on the power board(the board where your power cord plugs into the tv). Also look for any visible damage like a swollen/cracked or leaky capacitors. The top of the capacitors should be flat, if its swollen or cracked, you will know its bad.
Just a thought, but check all of the pico fuses for a blown fuse. The pico fuses look like a small yellow resistor. Some Hitachi's are famous for having a blown hi-volt ceramic capacitor and a blown pico fuse.
I think the red led on is a short protect indicator, but I could be mistaken.
