Sziasztok! A fenti erősítőhöz keresnék szoftvert, akár lehet régebbi is. Ha valaki letöltötte és meg is őrizte esetleg.

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.

Sziasztok! A címbeli erőlködő nem ad ki semmilyen jelet a hangszóró kimeneten. Amúgy minden működik rajta csak nem szól. Biztik, végtranzisztorok, diódák,kondenzátorok jók. Ha lenne valakinek rajza hozzá és elküldené hálás lennék érte. Szerintetek mi lehet a kínja? Bármilyen segítséget köszönök. További szép(szebb)napot!
