My 42" rear projection tv wil not turn on worked fine yesterday came home today tried to turn it on and you can hear it click inside and then the red light under "timer" just blinks i was wondering what was wrong and how much it will cost to fix it

I was handed the same model the other day.You're Lucky it clicks. The one I have is completely dead. I will give you an idea to try. Unplug your TV set......for a few days. Find someone who has acess to a variac transformer....And see if your tv will come on at about 70 volts...Somewhere less than 90 volts. If it will powerup, you will need the powerline regulator replaced. Part# STR X6459. I will purchase one for the tv I have and see if this will correct my problem.
