I have a Hitachi projector TV that is about 10 years old.
A few months ago, it wouldn't turn off after I pressed the power button, so I had to unplug it.
Then, after a few days it started working again. Now it is doing the same thing again.
When I press the power button to turn it off, it immediately comes back on, but there is no sound.
I press the power button again, it immediately comes back on, but with sound.
It keeps alternating like this, but refuses to turn off. What can be the problem?
