Sony big screen- turns off after it's turned on!

Sony big screen tv model num. KP-57HW40-MFG 2002, it turns off after about 5 seconds or so. It also displays a red LED that blinks 5 times! What can be the problem? Also were can I get a schematic of the boards inside? Thanks

5 Blinks- White balance

5 Blinks- White balance failure, IC 7101, IC7201, or IC7301 is bad on "CR", "CG", or the "CB" board.  These are the CRT driver boards on the end of the picture tubes.  CRT drive, IC309, faulty on "A" board, or the G2 is improperly adjusted. If you leave an e-mail address I will share a copy of the manual with you. Good Luck with this repair, and let us know how you make out with this repair.
