You know Sonys with that delay for the picture to appear all at once
after it warms up. Maybe that normal delay is when the impatient
customer is hitting the remote again and again.
I have a PC tech so used to operating one and two gigahertz fast
processors, that when he sits behind a 400 MHz system,he is may forget
and hit the enter button, expecting a quick response, puzzled. That
machine has it's own normal delays. Maybe so for the Sony problem...
