JVC TD-V711 kazettás deck fluorenszcens kijelző hiba
Sziasztok! Adott egy JVC TD-V711 kazettás deck. Nagyon szép, megkímélt állapotban van. Egy gond van vele, a kijelzője nagyon összevissza müködik. A fluoreszcens kijelző bal oldala ott is világít, ahol nem kellene, a jobb oldala viszont nagyon-nagyon halvány. Itt a tanyán fent van a kapcsolási rajz, Az 5V AC fűtőfeszültséget megkapja a kijelző. A feszültség enyhe növelésével a kijelző erősebben világít, viszont egyik oldala ugyanúgy halványabb, a bal oldalán pedig ugyanúgy világítanak olyan szegmensek, amelyeknek nem kellene. Lehet ha ki van öregedve a kijelző? Miket nézzek még esetleg meg, merre tapogatózzak? Esetleg tud valaki segíteni ilyen bontott kijelzőt találni? Endre

Turntable Victor/JVC TT-71
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
JVC KD-A2 kazettás magnó jobb csatorna nem működik
Sziasztok!
JVC KD-A2 HI-FI torony magnó része az képen látható hibát produkálja. A kazetta bekapcsolásakor a jobb oldali műszer "kiakad" és a hangfal csak halkan, nagy mellékzaj kíséretében szól. Ha mindent kihúzok belőle és úgy indítom a lejátszást,  akkor is "kiakad" a műszer. Mi lehet a hiba?
