Klipsch ProMedia 2.1 Amplified speakers


Original problem is no sub woofer output. Been through this one and recapped it and the common 2 burned 1K (R16/17)
resistors are replaced but the sub is still not responding. Volume control potentiometer is a common issue on these but
the L-R spkrs sound good.

Went by this webpage on the repair:
https://christopherbradshaw.net/The_Project_Bin/klipsch%20promedia%20subwoofer%20repair%20-%20page%201.html

On the schematic there is a sub-relay (sw101) powered by +V_HF line it
maybe is suppose to be +V_LF ? Without the relay coming on looks like the sub is disconnected.
The zeners (D03/04) that give +/- Vcc to the op amps seemed way off so I replaced them and the voltages seem much closer.

Theres also a sub-mute line on p104 to p101. Power supply shows the LF mute relay and interconnect diagram says it
gets fed from the LF amp. What is triggering the mute? I dont see a mute button anyplace.

Asztali CD - némításban?
Sziasztok! Asztali CD-lejátszóhoz kérnék segítséget (ötletet). Olvassa a lemezt, de nincs hangja sem a kimeneti aljzatról, sem a fülhallgatóban. Illetve valami mégis, de ha mértékegységet rendelnék hozzá, talán csak tized millivoltban lehetne kifejezni a jel nagyságát, mintha állandó némításban lenne. Előre is köszönöm, további szép estét Mindenkinek!
Autórádió CD-s
Köszöntök minden tanyalakót. Renault kazettás rádiót szeretnék cserélni CD-s rádióra. A kazettás Philips, és tunerlist feliratú, a CD-s VDO és updatelist feliratú. A CD-s nem jelentkezik a kijelzőn, ergó nem tudom bevinni a kódot. mit javasoltok, illetve mit kellene tudnom, a sikerhez, cseréljek kijelzőt is? Azt már tudom, hogy a tunerlist az I2L-vel kommunikál, de többet nem. előre is köszi. Gábor
