Üdv mindenkinek!
KDC-W312 tip. cd-rádió E-99 hibakódot produkálja.Nem pörgeti a lemezt olvasáshoz.
Merre induljak!
Szép estét mindenkinek!
Sziasztok!
A címbeli keverő-erösítő kapcsolási rajzát keresem. A tápba belenyúltak, az előerösítők tápja nem eredeti, sőt az egyik oldal 7812, a másik 7915, mindkettő egy tranyóval megfejelve. Mennyi lehet az eredeti táp? +/-12 vagy 15V ? Szerintem gyárilag tranyók sem voltak, de nem biztos...? Jó lenne egy rajz.
Köszi! Tomi
Kapcsolási rajzot nem itt, hanem a "Wanted/Katt ide" link alatt kell kérni!
I greet you! I would need the scheme of this "vintage" amplifier that needs to be "restored". The problem is that in the prefinal and final floor I have many "fried" resistors well, their value cannot be identified.I replaced the defective transistors: 2SC1509, 2SA777,2SB690 and 2SD 796 (each 2 pcs.) and the electrolytic capacitors adjacent to them. I could not go further because of the carbonized resistors that I do not know their value (I can only guess that they are values small, in the order of ohms). The schematic diagram I downloaded, from the address received by the kindness of a colleague is not complete - it is a single page (missing Q29-Q30-Q31-Q3 and resistors R115-R116-R117-R118 which are completely carbonized, at other resistors I could see their value).Thanks in advance!
Finally, I found the missing part
If stuck in the repair and you ask questions, please do it as follows: - Details: Give the exact model number of your device and the chassis ID (if there is). - If possible, please attach pictures of the appliance. - Anamnesis: Write down the exact symptom. If hard to describe the symptom, it is difficult to verbally defined clearly, attach pictures or sound of the phenomenon! - Tell what was you have done so far: search contact error, which parts has examined or changed yet, etc... The incorrectly named topic suspended and will be deleted after 48 hours! Suspended state while others are not able to comment until you correct the address. Subsequent repair of the defective title (within 48 hours) by clicking on the "Edit" tab can be carried out.
Sziasztok
Fenti 1 lemezes régi nissan cd tár kódot kér. Van esetleg hozzá kalkulátor? Gyári számot még megtudakolom.
Előre is köszi.
