Only other box with HDMI is a 4642.
A bunch of bad 4240's going bad seems odd. Those are the only boxes I really trust.
How are they failing?
I will see if I can get a 4642.
They just die, no power, or no picture. Sometimes there are some signs before it completely dies, like the box just powering off while watching or the picture freezing up requiring the plug to be physically pulled out and reset.
I have had multiple technicians come out. They thought maybe there was something wrong with my setup. Nothing is wrong. The big issue is these boxes are already pretty old (everything I have been receiving has had manufacturing dates between 2004 and 2006) and have already been marked as defective and repaired multiple times. Whatever the repair process is doesn't seem to be working.
