Sziasztok!
Ezt a gépet az osztrák szomszédtól kaptam. Kipróbálva az egyik oldal rendesen szól, de a másik oldala fél hangerő alatt recsegve szól ( torzan ) de ha fél hangerő felett van akkor rendesen szól. Merre lehet a hiba, az előerősítő részben, vagy a végfoknál. Szeretném megcsinálni, mert elég komoly szerkezet, köszi előre is az infókat!
Üdv!
A címben szereplő magyar gyártású végfokhoz szeretnék segítséget kérni.
Bármi jól jöhet (rajz fénykép,vagy csak szóbeli segítség)
Eléggé leharcolt állapotban került hozzám,szeretném megmenteni.
Végfok tranzisztorai jók mind (mj15003 mj15004)pár darab ellenállás van elégve de ez sem probléma mert az értékeik fel vannak tüntetve a panelon az egyetlen problémám az hogy mind 2 panelen van egy 8 lábú ic ami felismerhetetlenségig meg van rongálódva sajnos.
Csatolok róla pár képet.
Előre is köszönök minden segítséget.
Sziasztok!
Ennek az autós DVD-nek az a baja hogy egy bizonyos szögben ad csak képet a kijelzője, amikor elő jön a burkolat alól, de amikor megnyomom hogy menjen vissza alap helyzetbe akkor mindig van kép rajta, amíg el nem rejtőzik a helyére. Mi lehet a gond, szalagkábel?
I have and found most of the voltages as indicated on the circuit diagram, till op amp M 5218P; are near those specifed. The output on the centre of the two power transistors of both the channels are also alright.
While looking at the voltages on test points as mentioned on the page 7 for setting up quiscent current, these cannot be set.
Bit of history, the amplifier was lying unused for long time. Nothing in it has burnt. It was never opened earlier than this time, couple of days back.

While I was probing for voltages with DMM, with probe on collector of TR413 one of the fuses blew up. Later same thing happened on the other channel as well.
With the above as background can a Good Samaritan figure out feasibility of repair.
