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.

RM-R016 DAB rádió hangerőszabályozás!
Sziasztok ! Adott a fenti rádió melyik M62429 digitális hangerő szabályozása nem működött.A I2C buszon 2V jelet mértem cseréltem gondolván rossz ! A másik ic vel sem működött ! Az adatlap szerint már 0.8 V -t H szintnek érzékel!A processzor mely küldi a buszra jelet 3.3 V ról működik szerintem 3V körüli szinten kéne hogy adjon ! Gondolván egyet külső feszültséggel megemelem a jelelt 5V ról 10 KoHm keresztül a clock- ot megemeltem igy 3 V-let az impulzus szkóppal nézve ami hitelesnek mondható és lás csodát a hangerő szabályozó rendben működik !Várom véleményeteket! Szép napokat!
