CD-k belvilágában jártas kollégák segítségét kérem !
A tárgybani készülék kb.3 évig nem volt bekapcsolva,a CD kivételével minden funkciója tökéletesen működik ,pupos kondit nem találtam.
CD -t behelyezve 1-et forgat a motor és " no disc " üzenettel leáll . Optikát tisztítottam ,fejkábelt megmozgattam,de azt hiszem nem itt kell keresni a hibát !
Köszönöm a segítséget !

Üdvözletem Mesterek !
Keresem a JVC KD-R 821BT rajzát.
Kicsit leejtették a végfok hűtőbordára.
Nem akar indúlni.
A Tanyán nem találtam.
Előre köszönve és tisztelettel: Öreg T.
A probléma megoldódott .
Megint dolgozhattam egy nagyot , az előlap is kettétört, úgyhogy kuka.
Ha valakinek lenne előlapja felkinálnám a tulajnak.
Üdv :Öreg Tom

Victor TT-71, neon lamp does not light, speed is lower than normal. This is subsequent some short circuit the owner does inside the device. No further details.
I found out the VICTOR QL7 have the same motor driver amd I downloaded the service manual that I attached here in case this manual is not already uploaded.
Looking at the diagrams I found out that at TP3 (same with pin5 of IC803) instead if that rectangular signal, I have nothing but 5VDC and a negative or positive short spike whenever I'm starting or stopping the motor and
Under the circumstances I suspect IC803 is defective. The bad thing, IC803 is NPC SC8043. Also I wonder if the crystal is fine (except that I wonder what can be wrong with a crystal after some short circuit).
Does anybody have any more suggestion?
Also, where can NPC SC4043 be sourced? Also, a crystal 9.054MHz?
Thanks in advance,
Corneliu

Sziasztok!
Ez az autórádió a protect felíratott jelzi ki, eddig a végfokot cseréltem ki de a hiba megmaradt. Milyen gond lehet ez?
