I was at a yard sale and I asked them about a 32 inch TV. They said it was free because the screen did not light up. It turned out to be the same model and have the same problem that I have diagnosed before. It was bad capacitors in the HV power supply for the backlight.
Here is a picture of the bad 10 uF at 450 volt capacitors.
I replace them with 2 or 4 uF at 400 volt paper capacitors. There is a hole pattern already there for the larger capacitors. This picture shows the old holes and the new holes to use.
Here is what the new capacitors look like installed on the High Voltage power supply.
