We ran an HDMI from the computer to the Magnavox
We ran an HDMI from the computer to the Magnavox and got a fine picture but no audio. After several seconds, perhaps a minute the Magnavox goes blank and never again can we get an HD image.
Dish and Wii connections still work. The old DVD player still works. We never had any OTA TV. The computer says something like 'not connected'.
What would you conjecture happened?
Is the solution service more expensive than the value of the Magnavox?
