Solved! Samsung projection tv hcn4226w

[schneidcat]

hcn4226wI have the above Samsung Projection tv. It has power going to it, but no picture or sound. I know the signal is getting in because my surround sound has tv signal...

Unplug the power, stick your head behind it, and listen for a squeal when you plug it in. Common failure on these is a failed power supply (deflection) board.
