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

Üdv mindenkinek, em tárgyban említett csodához keresnék jó állapotú bontott mechanikát, sajnos teljesen menthetetlen, minden segítséget köszönök további kellemes napot.
Jó ebédet az étvágyhoz:
Keresem ennek a készüléknek a rajzát, eddig csak fizetőst találtam.
Holnap hozzák, CD el sem indul.
