Hi, Thank you for sharing this! I have a similar problem on my 921, but it only restarts, i don't have to wait to turn it on again. It shuts off and on again. Do you think that the problem might be in the same piece/part of this video? or in the same board? Thank you in advance for any help!
Hello, thanks for your comment, it could be the same problem. You need to verify the voltage from power supply module whether the voltage is constant during restarting or not.
Malam bos .punya vxs 920. Kalau sy hidupkan hanya bunyi tek tek aja .terus gk mau hidup.mohon di bantu bos bls
Displaynya sempat menyala gak?, ada kemungkinan masalah datang dari sistem power supply

Hello
I also have a pioneer vsx 921k amplifier
it is no longer heard in the speakers, because a software update failed, the old software did not work and the new one did not install
UE33 error occurs
the original remote control doesn't work anymore and I can't reach the settings
No settings can be made with the universal remote control
what can be done ?
Hello Petru thanks for your comment, regarding to your receiver problem as far as I know you need to do firmware update via usb, you can google to find the correct firmware as well as the the instruction.
Punya saya VSX 521K awalnya speaker centre tdk bunyi, trus colokan HDMI kadang bisa kadang tdk, kalau HDMI konek tp suara tdk ada terkadang modul apanya ya ini bang...
Diperlukan langkah pemeriksaan lebih jauh untuk mencari permasalahannya, mungkin saja dikarenakan hubungan yang kendor atau memang ada kerusakan komponen sehingga perlu diganti.
Hı🙋The sound from the left speaker output is low and scratchy. can you help? Thanks.
Is the problem occured from all audio input or on one audio input connection only?
@@rachssochannel again hello. I opened the cover at night. There was heavy dust. I cleaned the dust and restarted. everything is back to normal. thank you very, very much.🙋🙂
@@rachssochannel only the left speaker output was low and crackling. After cleaning the heavy dust, everything was normal. My wallet is relieved.🙂
Great to hear that you solve the problem
Kalau hanya kedip di lampu power nya saja?
Bisa saja karena ada yang short misalnya pada bagian power amp atau ada masalah di SMPS nya juga
Berapa jumlah transistor final keseluruhan chanel pak🙏
Ada 7 saluran masing masing ada 2(sepasang) total jadi 14
halo pak...
punya saya vsx 933,
problem nya chanel center speaker ada bunyi noise.
dan chanel front. speaker kanan mati.
kira kira knpa ya pak..
mohon dijawab 🙏
Penyebabnya bisa macam macam, harus dicek lebih dalam untuk melihat apa masalahnya
salam bang..saya dari malaysia..dan saya mempunyai sedikit masalah dengan PIONEER VSX-520x saya...saya berharap abang dpt membantu saya.. saya amp boleh on tapi tiada bunyi dari speaker..semua connnection tiada bunyi,,hdmi,aux dan optic cable tidak berfungsi...sebelum ni okay ja..amp boleh ,,cuma tiada bunyi ..harap sgt abang dapat membantu saya membaiki amp saya
Wassalam Bang....
Sebelum dan sesudah masalah datang apakah abang perasan ada perbezaan bilangan bunyi "klik" selepas press butang power on?
@@rachssochannel salam bang..yea bang..ada bunyi klik sekali bila saya on..lepas saya tukar channel dari DVR,CDR,FM,BD dan seterusnya ada bunyi klik juga..tapi speaker saja tiada bunyi..selepas power on ada bunyi klik skali bang.
Bila anda paham sila periksa bahagian power amplifier apakah ada ada kerosakan
Sya punya vsx 920k dinyala hanya stuck di POWER ON saja... Sudah coba reset juga gak bisa, mungkin bisa bantu?
Terima kasih atas komentarnya, ada banyak kemungkinan yang bisa menyebabkan masalah macet tak ada respon setelah power on, mulai dari firmware yang bermasalah sampai kepada kerusakan komponen. Perlu dilakukan diagnosa lebih lanjut untuk mengetahui masalahnya. Jadi saya tidak bisa memastikan apa masalahnya sekarang harus dilihat dan diagnosa lebih lanjut.
Saya punya vsx1020 protec ngga bisa on langsung mati bisa bantu service pak?
Ada lampu indikator yang sempat menyala gak sebelum mati lagi?
Indikator pqls blinking
Apakan ada lampu indikator yang sempat menyala dan apakan ada pesan yang sempat terlihat dari displaynya gak sebelum kembali mati total?
Pada saat di hidupkan ada indikator power on trus langsung mati
@@rachssochannel dulu pernah seperti ini saat unboxing awal beli ternyata masalah di listrik di rumah saya tidak stabil di bawah 220v dan bisa teratasi dengan stabilizer bisa hidup normal, saat ini saya check tengangan output stabilizernya 219,5 v
Guys do not buy Pioneer my malfunctioned because of Chips with factory defect and now Pioneer does not want to repair.
The technical assistance is terrible, any receiver beyond the Elite Pioneer work better.
Any sony, yamaha, denon is better.
This is my opinion...
Thank you very much for your comment, actually this problem is also depend on other factors such as local ambient temperature, the loudness and also time durations. The problem occured when I use it for quite long time at high loudness during the hot ambient temp at my event. It runs well until now without any additional problem so far after the repair.
