My tv will not turn on, it turned itself off and I can't turn it back on, there is no response at all when I hit the power. The day it stop working it was a very warm day. model L37W698
If the power supply works and there is voltage to the processor , the set must trigger. if not check the mains board for dry solderings, burnt drivers /capacitors.
