Very good po sir. Sir yong sub ko pioneer pag RCA wire gamit ko ok may sound. Pero pag wired na gamit ko econnect sa Input ng sub wl sounds. Sn po may video kyo how to repair or basic trouble shoot sa ganong problem. Thanks sir for sharing your knowledge its a BIG BIG HELP. More power to you keep up the good work and keep safe.
Hi, It's a pity this video is not in English or has an English subtitle as I found this to be the perfect video for my subwoofer problem as it shows the very same PCBs. But I can't understand what is going on or why, especially with the capacitor of the input board.
Hi, thank you for watching and my apologies about the language. Those capacitors have leaked and are related to the protection circuit. I suggest doing the physical check for those capacitors and replacing them if possible.
@@ARTaudio440 Thanks for the info, I'll check it out. Do you happen to have a schematic diagram of this board you could send me? I can't find it online anywhere.
I have the same sub - JBL 200/230. The red light is on, and there is no sound. I checked all the capacitors, and replaced one of the big ones because it had a very slightly raised top. That didn't help. There are no burnt signs on the board. All components visually seem healthy. The only sound I can get, is when I unplug and plug the black connector going between two boards - I hear a thump. I am sorry, I don't speak Indonesian, so I couldn't figure out some of the stuff you are saying. Can you please help with some instructions on what to test? I suspect the problem is on the lower board, but I am not sure. Thank you
@@ARTaudio440 replacing all 20 or so capacitors would almost be not worth it. Component cost plus work time would exceed buying a similar used amp. Right now, I am suspecting the opamp IC. The fault seems to happen when that is connected. Do you know if those go out often, and how to test them in circuit? Thanks
@andreym.562 hi, I think you are refering to protect IC which is similar to op amp. This type of IC cannot be test. Try replacing it. Also check the emitter of the power output transistor and make it sure that it has no DC out
@@ARTaudio440 in the video, I heard the relay clicking, and I think you determined the transistor next to it is causing it to not switch? Right? When I turn on the power the relay should click right? Or is it a protection relay?
Hi, salamat sa panunuod. Ang speaker in ay jan nyo po ilalagay ang speaker out ng external na amplifier like sakura or kahit anong amp. Tapos sa speaker out naman ay jan mo narin ikakabit ang mga speaker ng amplifier.
Hi, this subwoofer has no didicated amplifier for speaker, unless this subwoofer is connected to an amplifier with speaker output port. Speaker out from the amp must be connected to input speaker from subwoofer and the speakers box must be connecter to subwoofer output speaker terminal.
Nai on ko sya nag green mga twice pero di ko pa na test kung tumutunog. Tapos now ayaw umilaw yun lights pag ino On. Fuse lang ba problema nun? Same model nyan.
@@ARTaudio440 Nung binuksan ko may mga laruan palang kotse sa loob. yun medyo mabigat na kotse kotsehan, mga lima ata naipon lol Eh di ko naman alam binigay lang sa akin. Posible kaya nag short? Saan ba makabili nun 1.25A na fuse. Sayang naman.
@@ARTaudio440 Kuya last na lol Ok lang ba kung 1A lang yun fuse na ilagay ko kahit 1.25A nakalagay? Bale yun sub lang gamitin ko hinde ko lagyan ng speaker kasi ikabit sa amplifier yun sub. Hinde ba mag blow agad fuse? Meron 1 at 1.5A nilaktawan pa. Yun iba kasi 1.25A nga kaso galing pa china. 😂 size nya 5x20mm
Hi, thank you for watching ☺️ My apologies for the video language. The defect of this amp which I encountered was the capacitor that had leaked. My advice is to check some of the capacitors physically.
