Voltage Range or Specs?
Turns out my blown HDMI board was caused by a power company [Southern California Edison (SCE)] underground vault explosion. I filed a claim with SCE to have them payfor my repairs, they denied my claim. In speaking with them, I learned about their position, and reasons for denial.
They admit they had an equipment failure in my complex, on the subject date. BUT, they claim the failure did not result in any voltage spikes that caused my equipment damage. I asked how they knew there were no spikes, and I was told that BECAUSE NONE OF MY LARGE APPLIANCES SUCH AS DISHWASHER, REFRIDGERATOR, ETC WERE DAMAGED, THEY KNOW THERE WAS NOT ANY VOLTAGE SPIKES.
It seems their entire reasoning, (and justification for denying my claim) is based on a premise that any voltage spike, however small would FIRST NEED to damage large appliances before any AV equipment. Does this seem reasonable?
The power surge damaged two pieces of electronic equipment, my cable box and the AV receiver. I talked to the Marantz tech who is servicing my receiver, and he said these components are digital, so they are MORE sensitive than large appliances.
Does anyone know of any literature or specifications that are related to voltage ranges, etc? I'm looking for a way to refute the premise that large appliances HAVE to be damaged before an AV receiver.
Thanks in advance for any input.
