A címbeli egység hűtésével bajlódom. Pontosabban helyre kellene állítani a ventilátor vezérlését. Az alaplap ENH-213 jelű és a rajta lévő rommá égett R720 poz.számú ellenállás értékére, vmint a D720 poz.számú zener típusára lenne szükségem. Ez utóbbi láthatóan cserélt, a panel alján - bizonnyal egy "ügyes kezű pákász" által - vele párhuzamba kötött 20Ohm, 1/8W-os ellenállás volt. Ezért a ventilátor a bekapcsolást követő második perctől teljes fordulaton jár.
Az általam elért CA-MXG7BK SM. éppen csak ezt az egységet nem tartalmazza.
Segítő szándékotok megköszönném.

Egy jvc rx-888rbk tipusu erősitővel lenne egy olyan problémám. hogy halgatás közbe egy picit sercent és azota nincsen hang. Rádio tuner megy ki irja csatorna nevét rds stb. Az optikai bemeneten rátet jelet is felismeri. de minden hangjel ahogy megfigyeltem csak a bemeneti választok ig jut el(tc9162an tc9163an tc9164an) ki már nem belölük. szkopal nem látok rájuk menő se orajelet se adatot.
Valakinek ötlete? Hasonloval találkozot e már? Esetleg service manuál? Előre is köszönöm a segitséget!
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
