Sziasztok!
Ennek a gépnek az a hibája, hogy nem veszi be a lemezt, a mechanikát már átnéztem, de nem találtam problémát. Ha benne marad a lemez, áram alá helyezve kiadja azt, de be már nem. Külső táppal meghajtva a motort beviszi, és ki is adja a lemezt. A meghajtó icénél mértem 5V-ot, és 3V-ot, de mit kellene még ellenőrizni?
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
