Since I've read a lot about these receivers overheating I threw a small fan on top of the receiver and it seems to not cut out anymore (although I have only watched 2 movies since)
It seems to work well otherwise.
Is this a viable solution or is this receiver on its way out and on borrowed time?
Been playing music on it for a little bit via Bluetooth adapter through rca inputs. These are cutting out as well until switching inputs or restarting the receiver.
I've checked the onboard temp with the power button/tone trick and it's reading 39 degrees. However the fans never turn on inside the receiver.
So I popped the top off the receiver and using an Ir thermometer I measured temp in a few different places. Main heatsink is 99 degrees, hdmi board is 100-120 depending in location. Board under hdmi board has a chip on it that got hot during movies (145+!)
On music the bottom board behind the main heatsink is getting to 125-130 When music cuts out.
Again no fans running inside.
When I put a fan over top it all coils down quickly.
When I do the display/power button and time button to bring up onboard temp readings my display is reading as follows
V: 016 F: x
I assume v is current volume as it goes up when sound goes up.
F I am assuming is Fan, why is it X?
S I would assume is speed and H means it's supposed to be on high but it's not running?
T is temp and 39 degrees C. I wonder where the temp sensor is reading from.
