Need schematic MSI MS-16Y1

Hi everybody, can someone send me the schematic of MSI MS-16Y1.
The laptop works fine on external display via VGA & HDMI but not on onboard lcd. Ive check on the mobo, seen 3.3v on pin 2,3 and 19v on last pin.Change lcd & cable with same result.At times on power on display flashes for 2 seconds on lcd then blackout, but works on external display always.
