Re: A 9010 o n k y o amp , schematics & help please
Managed to acquire another amp .
Swapped out the volume control , to prove beyond any doubt that's the cause of the problem.
Stripped down the control again & this time discovered the issue .
There's a break in some of the tracks , which i didn't notice before ,as they are at the very bottom end where the plastic frame is .
tried to to link , but solder won't take & to be honest wouldn't have worked correctly anyway .
Now need to source correct control .
Can anyone help ?Attached FilesComment

Re: A 9010 o n k y o amp , schematics & help please
Been doing some detective work of my own.
ALPS RK16812MG seem to cover this range of motor driven potentiometers .
From there i found adding 04YA at the end brings up a 50K type on E BAY .
Ali Express is cheaper though.
Only issue might be is if potentiometer track differs , but at that price , worth a pop.Comment

Did that worked? My Onkyo a-9010 is with the exact same problem.
Oficial repairer wants 170€ which is almost the same that I paid for it 6 years ago, ridiculous.Comment

OK, this one dates back to 2015! I thought I had posted this, but realized I didn’t when I posted a picture of something else. So here it goes…
Back in 2015, I bought a pair of RCA WHP141 wireless headphones at Micro Center for $2. I even mentioned it in the best cheap/free scores thread right here. Just forgot to follow up with that.
As mentioned back then, these are (were) 900 MHz FM wireless headphones. No modern day Blutooth or anything like that. I knew they wouldn’t be great headphones or even that good… but the price was right!
So let’s take...

Hi to all,
I was given this TV, an entry-level 4K 50" set. Some have criticized its lack of contrast and relatively poor colour rendering, but for my needs, it's very decent.
I reset everything to factory settings, but this line keeps on fading in and out when watching a streaming channel from the Tizen firmware. Interestingly, it only happens when TV is warm, after about 1h45 of it being turned on.
Watching a movie from an external source doesn't trigger the line as easily (needs 2 hours), and from a normal viewing distance, is hardly noticeable. It...01-10-2024, 01:26 AM -
Hi all.
I have a Kogan 65' LCD Panel with a thin blue vertical line (top to bottom) on left hand side of panel.
The line just happens to coincide with the end of COF and start of the next COF (attached).
The line is permanent no matter what I've tried. I've tried pressure testing the panel (top to bottom) and all over, I didn't notice any difference with the line, either temporary or semi-permanent.
Also tried unplugging all flex cables, cleaned with isopropyl then re-inserting to no avail - line remains.
Hoping to fix... -
So I found my wife a pair of Sony MDR-100ABN's, and we were goofing with them yesterday. She has a new HP Sceptre with Windows 10. I don't know 10 at all so my blood pressure goes up trying to navigate the unruly interface.
I played with lots of settings yesterday, when I was trying to make the headphones connect to the laptop over bluetooth including, the MIC settings since we were playing with the Noice-Cancelling setting on the headphones. I ended up putting the MIC setting back to the Intel default on the laptop, but the output for the headphones.
Move forward to... -
Howdy everyone! I hope all is well where ever you are!
I'm attempting to integrate a couple of LED pods into an automotive reverse lamp circuit. The problem being, while the vehicle is running there is a 8.5v current present on the reverse lamp power wire. Needless to say is that all LED pods and lights dimly illuminate while the 8.5v is present, so the LEDs are always powered on while the vehicle is running. When the vehicle is shifted into reverse, the voltage changes to 12 volts.
I am uncertain how to convert this line into a switched 12v output line for the LED pods....
