Given:
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!
Egy kis segítség kellene.
Szeretném megkérdezni Tőletek, hogyan kell az Apple iPod nano készülékemet DFU modba tenni.
Előre is köszönöm!

Bizonyára többetekkel előfordult, hogy nektek vagy az ügyfélnek egy audió berendezéshez kellett távirányítót pótolni. Tv video csak ritkán gond. De aHi-fik és más audió cuccokhoz nem találni szinte sehol. nekem most Sony RM-D591 és RM-S310 távirányítót kellene pótolnom. Persze HA meglenne az eredeti akár romokban is egy taníthatót meg lehetne játszani. De mivel most vásárolt gyűjteménybe való készülékekről van szó csak valamiféle legyártott pótlás a megoldás.
Várom az ötleteket.
Köszönöm Laci
