Harman/Kardon AVR65 RDS - Sudden Sound increase
Hello! Harman Kardon Receiver /amplifier AVR 65/RDS ! increases the Volume by it self some times (Suddenly) pse. advise .. Works Well otherwise! Best..Regards Rune..Sweden
May be useful - Harman Kardon information
For your information to repair Harman KArdon HD710 Player uses a KSS210B Pickup (as spare, original unknown) can be changed without any other servicing Harman Kardon Receivers; Series AVR 2000,3000... "Looses memory issue"- gold cap at the front pcb defective. May be changed to a 1µ cap but you have to solder 3 other elko´s to the other side. Keeps memory for a longer time. "Hum noise for the first 5min, warm up" - right lower side at the main pcb: elko 7800µ dead- you can see it at the "cap of it". Replace both (7800µ and 2200µ) to new versions above 25V. "Fuse burnt voltage selection; no green led´s flash, no sound"- cap 2200µ make a short circuit (next to 7800µ). Change these elkos! If you want to make it better... change the 7x 10µ caps for the regulators too. Resolder all points there. "volume changes self to max. or min." change the two resistors at the front pcb close to the volume encounter. be sure that there are both sides 5V! "everything is functional but no sound; but sound from the 6.1ch in" TC9273N-07 is dead (shorted). Have a look at the two caps and the security resistors beneath this chip! My be dead too. Replace this chip only by the -007 version. others will not function. Be careful with the bigger stripe cable! the contact lines are loosen from the plastics. You can help yourself with a "second glue" under these contacts. So i hope i can help you... cheers SG.
Harman Kardon protect hiba! MEGOLDVA!!
Sziasztok! Harman avr 255 protect hibával kikapcsol, hamar kiderült hogy az egyik végfok tranzisztor a ludas.Cseréltem is a párost (2sb1560 és 2sd2390) de továbbra is protect hibát ír és leáll.Ami furcsa, a hangszóró kimeneteket mérve a cserélt páros bekapcsoláskor -27 volt körülre lemegy, a többi aránylag nem sokat ingadozik, -2 és +3 volt között maradnak.Kérdésem hogy ott még lehet valami zárlatos? Ha kiforrasztom a cserélt tranyó lábakat és úgy indítok akkor elindul az erősítő.
