broken 57s500 hitachi projection tv

I JUST PURCHASED THIS TV ABOUT YEAR AND A HALF AGO FOR APROX. $1200. iTS HARD TO FIND ANYBODY TO WORK ON IT. ONE LOCAL "TV REPAIR MAN" HAS NO IDEA. I PAID ANOTHER $125 DOLLARS TO DRIVE 85+ MILES TO TELL ME IT WILL COST $750 TO REPAIR. MY PROBLEM IS AS SOON AS YOU TURN IT ON IT LIGHTS UP AND SHUTS RIGHT BACK DOWN. I WAS TOLD IT NEEDS A NEW HIGH VOLTAGE MODULE. IF ANYBODY COULD HELP ME OR POINT ME IN THE RIGHT DIRECTION IT WOULD BE VERY MUCH APPRECIATED.
