Yamaha RX-V773 receiver takes long time to warm up before I get sound. The time has increased to over 10 minutes. Any ideas what could be wrong
Hi. I have rxv773 and it had the same problem. If u turn it on and after reley clicking 2 times fast and 1 time after about 8 seconds, look at the display if you see speaker ikons. If u don't see them and there is no sound. You wait those 10 minutes when sound comes back and look if the icons apear at the same time you got sound. If that is the case, you have bad DSP chip inside on the hdmi board. You could open the yamaha cover and see it right away on the top board at the right side. The chip is D80YK113CPTP4. That is the bad one. If you apply a heat for about 20 to 30 seconds with the heat gun at medium settings, you could fix the problem for a day or two or maybe a month. You need to replace the chip with newer one D80YK113DPTP4 . That dptp4 is updatet chip from cptp4. You can find those on aliexpress.
I have yamaha ex395 turn on for 3 second ten turn off how to fix
Unplug all your speakers and components. Then turn on, if it still locks up you have one of maybe 5 safety features hooked up that are built in to stop your amp from blowing. You will need to replace board or have some cool tech dude desolder and isolate . Look for wiring diagram for safety shut down system. Sorry but if it doesn't do it after you disconnect every thing then check each speaker with ohm meter to read factory specs.
Yamaha rx-v679 only standby red power bottom when you turn on its only blinking what is the problem ?
The shut down is a protection circuit kicking in to protect the receiver from damage.
This could be caused by a short in one of the speakers or components, thermal fault, or an internal defect in the amp itself.
You can try a few fixes yourself. To begin, power the receiver off, and disconnect all speakers and components. Try to turn it back on in Tuner (am/fm) mode and see if it will stay on. If it does, power off and reconnect 1 speaker, then power on to test again. Continue this process until you isolate the speaker or component causing the problem, or until everything operates normally
