LQSC Premium Nylon Fabric Dust Cover Protector Case for Sony STRDH550/STRDH770 Receiver

SDRT 8750 and it's a 7-point cue channel surround sound receiver with HDMI so it's not that old it was actually had a surge from a lightning strike and it caused it to go into protection mode so when you turn on it shuts off because there's some kind of short somewhere or it's overheating it's not overheating so shorted out something first thing you usually want to check is the power supply and if it's an older unit it's probably the power transistors and these resistors you can test them there's some tutorials online on YouTube Dedan helped me I check the resistance make sure they weren't shorted out and this might be different for you if you have something else that happens if there's a power surge for your power line or your cable line and actually took out a TV a lightning strike hit a cable line and went through the cable for the antenna input and actually went through the HDMI boa
