Question about Sony STR-DE898 Receiver
I had a lightning strike a few months ago and my receiver quit working. No sound comes from it but everything turns on and lights up but no sound. I reset the receiver and everything I could do but I wondered if there may be a quick solution inside with a fuse or something I can do myself before i give up and decide its fried.
Could be an internal fuse blown but most later electronics use a special kind of resistor called a varistor.
These devices are across the AC line and do nothing until the voltage difference between the two lines, hot & neutral, exceeds a certain voltage; this is typically ~200 volts for 120 service as in the US and higher for 220 service on most of the planet.
They are disc shaped, will be from 4-5mm (~ 3/8") to as much as 25mm (~1") in diameter and if ever zapped, they are charred and with chunks missing. When their design voltage is exceeded, their resistance drops from near infinite to a few Ohms which then causes the fuse to blow. You can replace the fuse and choose not to replace the varistor but then you will not longer have even that minimal protection against spikes.
For folks in lightning-prone areas, the installation of a 'whole-house' surge suppressor is highly desirable, will cost ~$250 US and have an insurance policy against losses of $10-$25,000 US in case you still lose devices protected.

a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
