You don't suppose it's due to power surges, do you?
Personally, I'd like to be off the grid. We have had two price increases this year and we're looking at more later. This, because Wisconsin allows WE Energies to be a monopoly.
Quite likely. I know this is not popular to keep preaching this, but everybody with a significant investment in their system needs: -
Whole house surge protection.
All units containing microprocessor circuits need to be run from a smart UPS that has a response time for high and low voltage fluctuation in the range of 1 to 5 msec.
That just has to be part of the AV budget now, there is no ducking the issue.
And this is the issue as I see it: -
Increasing complexity and power of microprocessors. This causes an increase in fragility as the semiconductor layers are thinner, and more susceptible to damage.
To combat this, all units with micro processors need protection. That means whole house surge protection, not surge strips. running these units from smart UPS type devices. I think this would reduce failure by a big margin.
Avoiding sources of heat around microprocessors. Make arrangements for superior ventilation. Use separates where possible instead of receivers.
The new lead free solder is a definite issue, as it has a tendency to sprout shorting whiskers and an increased rate of dry joints.
Declining standards of chip manufacture in the worlds two largest fabricator groups, one out of China, the other out of Taiwan. This is of concern to the industry, and plans are advancing for another fabrication consortium, with factories in the Dresden area of Germany and New York.
Pushing price points too low. There really is far too much junk out there, that are a waste of resources and a contamination recycling nightmare.
All of these issues are combining to cause reliability rates to be on the decline.
