Hi guys,
This is my own (actually present to gf) amp which I am not even using so much.
Recently started to use optical input from TV which worked great.
However recently the link went down.
Few days ago I opened it up, cleaned PCBs from dust, then came back to life.
But today it did the same thing again.
On TV when I change setting from speakers to just optical and other way around, audio comes up only for very short moment.
There are 2 optical inputs, both behave same way.
I found schematic which is attached.
I hope this forum experts... -
So, I have a really bizarre issue that I'm struggling to identify the cause of. Working on an 820-02020 board with some bizarre keyboard/input-source character mapping. My suspicion is a possible damaged SPI ROM (U1970), perhaps, but I'm really not sure in this case:
1. The issue is pretty weird, but when installing MacOS, I noticed my WiFi password did not work. I quickly realized the special characters (!@#$%^& etc) were not mapping correctly.
2. I noticed the keyboard layout/input-source is defaulting to JAPANESE every single time I restore the board. I am not... -
Recently I was given for free a Sony RCD-W3 with the following symptoms, CD recorder drive reads CDs without any issues (haven't tested recording function yet because I don't intend to burn CDs on that machine) but the reader drive shows disc error after some seconds of it trying to read CD. Tried both CD-Rs and commercial audio CDs with same results.
First thing to do was to clean the lens but that didn't change anything. Googling the issue revealed that this is a common issue on several Sony CD recorder machines and the culprit is SMD electrolytic caps located on the PCB bellow...05-05-2024, 02:04 PM -
Oh wow.
As in the other thread I was trying to revive/re-bootstrap an old Apple IIe and wasn't successful reading or writing any disk. Both drives behave similarly.
Then I was wondering, what about my PC floppy drives? I have a HH 5¼" HD drive and a combo 5¼+3½ drive. I tried formatting the disk that wouldn't work in the Apple and it didn't work in the PC either!
Then I tried a HD 5.25 disk ... it won't even touch the disk either! Just like the Apple DD disk, "Not Ready!"
Weird. Seems the PC drive is having trouble clamping... -
