I have a hitachi model 50ux19k Rear projection TV.When i push the power
botton the relay engages but the power light will not come on and the
tubes do not light.I have electronic repair experience on sound sys.Two
years ago the tubes were replaced professionally.Is there a watchdog
circuit or overcurrent protection in the PS.I have a digital meter but
do not own a Scope.Any fairly simple solutions such as B+ Adj.
