Post detailed pic. of the bottom side, maybe someone can trace out the issue.

Maybe replace C141, looks like .1uf 50 volt. I don't see C141 on your board are there any .1uf 10 volt caps on it?Last edited by nomoresonys; 08-23-2024, 06:00 AM.Comment

Changed the green caps on the A1020 PSU and it started to work. Forgot it on over night and the display is bright again. Those caps were Samxon's and not within their values.
The A1060 is totally dead, even the mechanism is not working, tried it in the other unit.Comment

Totally dead, start with checking the fuse, F1.Comment

Didn't see any green caps, can you highlight them on the picture? It may help someone else with the dim issue.Last edited by nomoresonys; 09-01-2024, 03:44 PM.Comment

They have already been replaced...Attached FilesComment

Lol, yeah I got that, was wondering which ones were green, weren't you?Comment
-
C21, C33, C32, C1 and C2 were changed. So far it's working with a DVD, I have no Bluray discs yet.Comment

And did you check the fuse on the dead one?Comment

Ok, so not completely dead.Comment

Ok, answer a couple simple questions, does this player have buttons on it or is it only workable with a remote, you are sure that the remote you received is the one that goes to that player? Do you have a way to test capacitors, if so test them all. If you have not yet test all resistors and diodes on top of board. Now you say you have some voltages, can you tell us the voltages from the connectors, report all of them, in similar format, pin F+ and whatever voltage is there and whatever the expected voltage should be as labeled, F- the voltage of it, gnd which should have no voltage of course, -24 voltage etc. etc. for each pin of the connectors. If you have already done some of these tests just say so, it takes way too much time to keep going back over and read every post.Comment

I dismantled the whole unit, all caps tested were ok, (not every cap measured). The mechanism was also dead as it didn't work in the other player. The remote control is for the A1060, but I can use it with the A1020. Any button on the front panel didn't work, and it made no sound, unlike the A1020 which can be heard after power on, now its display also work..Comment

Thanks, and how about those voltages, with the actual and the expected as seen on the legend/map markings.Comment

All voltages in 0,1-0,2 in tolerance, but the -24V to front panel was missing.Comment

Help Needed: Yamaha RX-V485 Network Issue After Firmware Update (WN9711 Error)
Hi everyone,
I'm facing an issue with my Yamaha RX-V485 receiver. During a firmware update, the process failed, and now the USB, Bluetooth, and network functionalities are not working. Occasionally, the receiver displays the error code WN9711.
I came across Yamaha Technical Bulletin No. 0103, which describes a similar issue for models like the RX-V4A, RX-V6A, and RX-A2A. According to the bulletin, the issue can be resolved by shorting soldering points (e.g., J260 for RX-V4A or... -
I have an old Yamaha RX V675 receiver which is starting to develop issues with the sound, although it doesn't quite match up with what folk normally report with these.
From cold, the sound cuts in and out. When this happens the amp is losing sync with the optical input (speaker graphic disappears from the front panel). But this is not resolved by putting the unit into pure direct mode. After a couple of minutes this resolves, although there are occasional clicks from the speakers after that.
At first I thought it was either a speaker relay or the DSP, but I don't think... -
Hi.
I have an old YAMAHA CLP-550 without sound. (Some times I can get some kind of noise or distorted sound)
I have replaced all green marked elements, but it gave me nothing.
The IC12 chip LC9116A-105 (red marked) remains under suspicion yet.
But it is custom YAMAHA's chip, and I can't find any information about it.
Maybe somebody came across with the same issue?
Any information will be very useful. I will be very appreciated.
Thank you.... -
Hello Everyone,
Greetings!
It has been very long time that I opened up my garage again because I got something that I could not stop myself and this time I have a Yamaha RX-A1020 super powerful (at least from inside structure 😉 ) AV receiver. When this unit came to me this Saturday it was full of dust and what not but the standby LED blinked when pressed and power relay clicked once but no display. It worked 3 times after normal reset like other Yamaha receivers and then again it had to be unplugged to get his behavior back. I opened everything and cleaned it up and...09-14-2024, 11:25 AM -
My friends Yamaha RXv-485 receiver has stopped communicating on network and Bluetooth, we decided to make a firmware update from USB stick but after a while it comes up with the message "unknown".... Its the latest 1.87 version we are trying to load and it seems like the is no firmware in it at the moment as it does not state the old version ?
Any ideas how to resolve this issue?​
