Receiver repair
 

My Pioneer receiver (VSX-D457) must have gotten zapped by a recent
electrical storm (also knocked out our phones). When I turn the power on
the receiver, the led display cycles on and off at approx. 2 second
intervals. Any electronics wizs that could point at a starting place for
repair? Thanks much for any help.

Step 1: get a schematic

Get the service manual, and then follow through troubleshooting, starting at
the power supply.

This is actually a common symptom after a mild lightning strike on a
Pioneer.

One or more muting transistors bad.

A tech should really do this repair. Some Pioneer's hold voltage after
unplugged, even.
