With mains connected and primary side OK, it should be 100..300mV. If it's not, check:<br />** fuses<br />** mains voltage-drop capacitors (C8, C11). They may degrade over time, due to mains voltage surges. Replace these with the same or higher AC-rated foil capacitors only!<br />** 1u/50V filter capacitor (C9). Replace with the same electrolytic ot X7R ceramic 1u/50V capacitor.<br /><br />MAIN(2) board schematic with highlighed items:<br />http://dl.dropboxusercontent.com/u/59011027/2015/yamaha-rx-e410-e810-main-2.png<br /><br />Complete service manual:<br />http://elektrotanya.com/yamaha_rx-e410_810.pdf/download.html<br /> <br />WARNING 1: primary side of MAIN(2) board is galvanically connected to the mains. If you don't know what are you doing and/or don't have a mains isolation transformer, leave the repair to the certified serviceman.<br />WARNING 2: before handling the board, don't forget to disconnect the mains and discharge capacitors at primary sideAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-4070917281892144929.post-29498301254757371982014-04-25T12:27:04.869+02:002014-04-25T12:27:04.869+02:00I,ve got same trouble.in Yamaha RX E 810; how do y...I,ve got same trouble.in Yamaha RX E 810; how do you Reset manually??<br />GND to Reset or +5V to Reset??Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4070917281892144929.post-27226656566311624912014-02-09T12:32:13.380+01:002014-02-09T12:32:13.380+01:00You can use capacitors above 12V.
