There are no consumer replaceable parts in the unit. Have it serviced professionally.
I cannot get the TV to power on. It has a buzzing(like crickets at night) sound when powered. I had it run through a cable box and thought that might be the issue but I disconnected the box and the cable to the TV and I get the sane buzzing and the TV does not come on. The model number is F32TF600YX1 and was purchased in 2003.
