Sony Str-de197 Will Not Turn On.
My Sony STR-DE197 was plugged into a power strip, but not operating, during a thunderstorm with lightning. Now it will not turn on. The fuse is fine. Any ideas on any other reason for lack of power (e.g., possibly a thermal fuse)? Thank you for any help.

Sony amp power supplies are based on a separate standby and main power transformer. It seems the standby power works since you hear that click upon pressing the power button. You should find an AC power board inside, this will have a small transformer (for the 12 VDC standby power supply), a relay, and various supporting components. This relay should allow AC into the big main power transformer. Try measuring for 120 VAC at the primary of the main power transformer. This is a good time to mention that there are deadly AC and DC voltages inside a receiver so use caution and do this at your own risk. There is probably a fuse for the main power trafo primary, as well as some or all of the secondaries. When replacing fuses, never use anything but the same type and rating (current and fast/slow blow). If the thing is blowing fuses, you can't fix it by putting in a higher rated or slow-blow fuse. You will only cause more damage. The VFD display is powered from the main power trafo so no display tells me there is maybe a blown primary fuse. (The secondary for the VFD usually isn't fused).
