I have a Orion SLED 4468w and the tv will come on and then it will shut off. I tried to replace the LCD main board but it still is doing, what did I do wrong?

Really Did not find a solution because we already know the problem. i.e the mani/digital board. BenQ will not sell us the part. We are still looking for a supplier.

NEVER NEVER Buy BenQ

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.
