Sziasztok!
Nem biztos, hogy jó helyen nyitottam a topikot, mert vélhetően nem egy csúcshifi a készülékem...
Erről a rádióról szeretnék informálódni... Tudja-e valaki, hogy pontosan mi ez (név, becenév, típus)? milyen autóban volt?? van-e saját előlapja, vagy a többi már az autó része?
Előre is köszönök minden információt!!!

Sziasztok!
Yamaha DSP-A 595a azt produkálja, hogy bekapcsolás után pár másodperccel lekapcsol. Végfokok jók, a szervízmenübe lépve ezt írja ki: 1 DVD/LD DC 0%
Ez mire vonatkozik? Azt írja a SM, hogy az 5V a 100%, ebből arra gondoltam, hogy vmelyik 5V hiányzik, de én rendben találtam. Tudna valaki segíteni?
Köszönettel
Attila

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!
Igény lenne erre a gépre a családban, így előszedtem. Távirányító nincs meg,, de az a legkevesebb.
Bedug, meg se nyikkan. Megjegyzem egy nagyon profi gép ahhoz képest, hogy egy hordozható kis valami!
Motoros potméter, reflexcső, forgófej, hihetetlen :)
Nos, a T901-es trafó hiányzik belőle.
Rajz 47. oldalát nézve mintha 12V-os lenne.
Megerősítetek? Illetve mekkora teljesítményűt kéne belerakni?
Az eredeti jópofa kis sínrendszerben volt.
Üdv:
Pityesz
