Facing TV Problems? Ask a TV Technician.
Hi there and welcome Ted.
To clarify, is the TV itself not coming on at all? Or the Direct TV box is not functioning?
This points to a capacitor on the powerboard that has been failing but was still at times functioning which is why you had the previous issues, but now has totally failed
to confirm this, can you please remove the power to the TV (so unplug it from the power socket).
Then on the actual TV, hold the power button for 60 seconds then release.
Then wait 2 minutes, connect the power again to the TV, turn it on and tell me please if it is now operating correctly.
Let me know the results please
