Now searching at standby energy source schematic Theres nothing at all on PWRRY when power button is definitely pressed.Furthermore Ive examined Beds9, ACDET voltages, and both seems to end up being increased than its created on schematic.However, looking more: Theres no place else S i90009 is definitely connected, simply to an 3.3V regulator.Which makes stable 3.3V voltage for microprocessor(Ive examined with scope).
Power switch is working fine, tracked back again to the microprocessor. Ive furthermore manually connected exchange RY151 from 5V power source and exchange works simply fine. Ive furthermore tested output of thermal sénsor IC134 LM19, which result is about 1.75V, therefore temp can be not triggering this. One important point - main power offer caps appears wierd to me, their vents are kinda bloated. Yamaha Htr 3066 Full Assistance ManualFull assistance manual - Edit: Problem had been that microcontroller recognized low air cooling voltage multiple times. Ive handled to get into analysis menu, which resets thé mcu and today receiver works just great. ![]() Yamaha Htr 3066 Code In TheIf youve obtained a fault code current, it will end up being displayed as a P program code in the front side screen Chris Williams. If youve got a problem code present, it will be displayed as a P program code in the top screen Chris Williams In the event of á high-currént shut-down, thé above treatment will create only a click on as the exchange cycles once. Blown funnel, shorted bridge rectifier or major filter cover, etc. Yamaha safety circuits of current years are usually so fast the display never arrives up. As soon as the over-current protect offers been involved the recipient will perform nothing at all, except display the Standby Brought when you press the StandbyOn switch. Now shifted to OPE3. ![]() H9 46.9 VDC when gauge with regard to MGND. ![]() PWR RY 0Vdc ACDET 34.3 VDC Air conditioning unit input 249 VAC Air conditioners result on the subwoofer transformer 18.8 - 0 -18.8 Vac Are usually you mentioning to some various other design This makes no sense relating to an RX-V2067. Your reading through for T9 cannot, do it again, CAN.NOT. I would suggest re-checking that you have a appropriate ground research, or examining that framework ground is usually in fact chassis surface - some link to chassis not becoming produced by the signal panel or some other connection. For example - if the back panel screws are eliminated you will have got no ground research and mistakes will occur just for that reason.
