Need the service manual for Viewsonic VP150M

[Microunit]

Any one has the service manual for viewsonic VP150M. Actually I really need the schematic for the inverter(A48205941) which does not function correctly. When the power is on, the screen will show only about one second after the initialization. Then I suspect the inverter has the problem. First the fuse was blown. Even though the new fuse is replaced. The screen shows one second then black out again which tells me that it is not the backlight. I think it can start up the backlight but can't maintain the right voltage to keep it going. There is no reading after it blacks out. Anyone has idea how to resolve this problem. Thanks in advance.

Can you tell me the voltage and current rating of the inverter board surface mount fuse? Thanks.
