Hi Guys, My first time on the forum.
I have a Yamaha HTR-5460 Receiver that I have used for a few years. It has recently developed a problem of giving a pop in the speakers and then shutting down. This is intermittent and might happen after an hour or a couple of days of playing.
I have put it into Diagnostic Mode and it comes up with code “PS PRT 020 B”. According to the service manual “PS PRT” signifies a power supply problem in the mains transformer, 5V or 12V DC supplies. I'm assuming that the “020 B” part of the code would define which one of these...11-03-2023, 07:00 AM -
I have a Hitachi HTA-DD3W AV receiver and when I got it I tested it working fine with speakers but it needed a clean inside because it had signs of moisture in it but it was fully dry with bits of wood chips, I guess this was left in a shed so I fully disassembled it and cleaned it with isopropyl alcohol very carefully, some de-soldering was also needed but now its very clean, luckily there was no rust on any components and all the capacitors are fine with no bulging. When I turn it on I hear a relay switch on then a few seconds later another relay switches on or off and the display has a "-PROTECT-"... -
Hi all,
This is a repost since I never completed this fix. I just left it, but now the receiver powers off into safe mode and does not complete the Self-Diagnostic when i start with those buttons pushed. It says it is, but does not do the diagnostics and does not show any faults or that it has none, which it should do. So here i am again. The previous post did have a schematic but I think it was cut off somewhere. I do not know what board it is referring to. Any help would be appreciated.
I have searched through the forums and have not found anything about my problem. So,...08-30-2023, 08:35 AM -
120v ok, No voltage on the connectors, Fuses OK, 165v DC on the main capacitor... -
I have a Yamaha YST-C10 mini-stereo that was made around 1990. It has two cassette decks, a CD player and an AM/FM tuner. When it is turned on in tuner mode, the cassette deck capstans normally run for about one second and then the radio will begin to play. Currently, however, the capstans run continuously for about five minutes followed by running intermittently in two second bursts for another five minutes. The radio will play softly when the capstans stop during the intermittent phase. After about 10 minutes of this, the capstans stop completely and all the stereo functions work fine.
