Hi guys,
i saved this HiFi from trash. It only problem last is the VF display - it shows nothing. I searched for simmilar topics and found one, but still havent figure it out.
I have schematics, replaced caps C615-C620, i have negative -25V to -30V on all display pins (including fl1, fl2 - heater) but no AC voltage there.
AC voltage is present on c615 cap (around 10v as i remember)
Between FL1 and FL2 i have ~6 ohms, no AC voltage. From FL1 or FL2 to GND i have 3,5V AC (and -29V DC as i wrote) or jumping 12V to 0V (short + protection?)
Schematics: https://tinyurl.com/3s3b4zks
Searched for dry solder - no luck.
Any help would be great, thanks!
