2006 RCA projection TV just wont turn on nomore!

your TV just got tired, is there any indicator lights in front of your TV? is it blinking?
if it is blinking it means your TV is in protection state , it is protecting itself from further damaged

if no light at all, try to plug your unit to a known wall outlet that is working

if still no light, outlet is good, give a ring on the dealer or visit the manufacturer website maybe still in warranty period,
if not on the warranty period anymore try checking on the power supply
if no lights at all check fuse
if lights blinks check for power supply output voltages, it might not have enough to power up the horizontal deflection circuit board
