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.
SHARP RT-110H KAZETTÁS DECK hullámzik a hang
Helló! Szeretnék tanácsot kérni.Van ez a sharp tipusu 1000éves kazettás deck-em.Most bukkantam rá a garázsban kipakoláskor.Kipróbáltam egy jobb minőségű kazettával de hullámzik a hang,Meg kicsit mintha hörögne.A magas hangok mintha eltünnének belőle elindulás után.Esetleg érdemes vele foglalkozni vagy tegyem ki lomtalanításkor??? Jó volna ha sikerülne valahogy életre kelteni mert rengeteg kazettám van elrakva.Meg talán kicsit visszavinne abba az időbe amikor kazettáról nyomták a diszkóba a zenét. Köszi előre is
THOMSON DPL-680 lefagy MEGOLDVA
Tisztelt Tanyalakók. Van egy címben szereplő házimozi erősítőm, aminek az a baja, hogy bekapcsolás után három művelet hajtható végre, aztán lefagy. Kb. 1-3 perc múlva újból lehet három műveletet végrehajtani, majd ismét fagyás. És ez így ismétlődik. Arra a következtetésre jutottam, hogy a hibás ez a microkontroller. ht48r05a-1 Kérdezem, van-e valakinek bontott, de jó , vagy új, szóval minden megoldás érdekel. Üdvözlet
