Best way to check voltage regulators is to probe them for voltage at power up. You get just enough time to see if they are stable or if they are acting strange. Some regulators will not fail short so it's best to take them out and test them or test them in circuit.
You didn't check the PROTECTION HISTORY at the beginning to know the possible failure problem, so how did you confirm that the STK433 needs to be replaced? And you measured the voltage regulator to confirm that they are all normal? I have a rx-v3067=(rx-a3000) display PS2-PRT 174, abnormal voltage, also trying to repair...
if you get half a second at startup check the voltage regulator board and each regulator for stability. Some old caps can cause regulators to fail. Some Yamaha models have no access to diagnostics, it depends on the age. You can get the datasheet for the amplifier modules and test them for shorts once you know the pin out. Thankfully they stopped using modules and went back to transistors before and after a certain date
Hello po, yung Yamaha rxv- 485 KO po is ayaw nya pong bumukas, naka standby lang always ung power button light nya. Is there is serious problem po sa receiver ko? Thanks po!
Maaaring ito ay maraming bagay. pinakamahusay na dalhin ito sa isang eksperto. magiging napakahirap ipaliwanag ang lahat ng mga problema. suriin ang impedance selector sa likuran kung mayroon ka. tanggalin sa saksakan ang lahat ng speakera kung sakaling masama ang isa. maghanap ng mga medium sized na ceramic capacitor sa stand by power board kung saan ang pangunahing power cable ay ibinebenta malapit sa mga piyus at maliit na transpormer. suriin ang mga boltahe tulad ng sa manwal ng serbisyo. maghanap ng masamang capacitor sa paligid ng anumang mainit na lugar. At tingnan kung may masamang amplifier transistors, preamplifier transistors o masamang amplifier modules.
Hindi mo sinuri sa umpisa ang PROTECTION HISTORY para malaman ang possible failure problem, so paano mo na-confirm na kailangan palitan ang STK433? At sinukat mo ang voltage regulator para ma-confirm na normal silang lahat? Meron akong rx- v3067=(rx-a3000) display PS2-PRT 174, abnormal na boltahe, sinusubukan ding ayusin...

Please make video for rxv373 DC PRT 255h
Watching po master ❤️😊
SALAMAT MASSTER MARCO.
Gumagawa po ba kau av reciever sir

.sir...sn po loc ng shop nyo...gnyn dn po sira ng yamaha ampli q
Davao city po
Parang ongkyo
MAGANDA TUNOG NITO MASTER BASTA ORIG.
Ay lang..
Bakit walang mike jack input yang Yamaha av receiver. Pano Po magkabit Ng mike dyan for Videoke purposes po
Need Ng mixer
Boss yung RX-V461 ko ayaw na magopen na saksak sa 220V sire yung fuse tapos wala na display pasay location ko boss
