gradysanford Posted July 14, 2022 Share Posted July 14, 2022 (edited) What I was looking for, exactly. I recently purchased a set of these for $70 "open box," and I intend to use them for many years to come. We'll see what happens! If necessary, I might have to get out my Weller soldering iron. basketbros Edited July 15, 2022 by gradysanford Quote Link to comment Share on other sites More sharing options...
jkwkapproved Posted August 16, 2022 Share Posted August 16, 2022 Hey, Jeff! Can you hook a guy up with your attachment? It keeps telling me it's unavailable. I might just be an idiot, however. 🤷♂️ Quote Link to comment Share on other sites More sharing options...

jaydoc79 Posted November 4, 2022 Share Posted November 4, 2022 I have the same issues that you described - sub seems to output audio, both satellites are dead. Removed the sub’s back plate and took a pic. One more here. Any idea what’s wrong with my unit? And is it “fixable”? Thanks Quote Link to comment Share on other sites More sharing options...
JeffC Posted June 7, 2023 Author Share Posted June 7, 2023 (edited) Repair summary is: Replace C22 on the circuit board with a new 50V 22uF capacitor. I fixed 2 sets with the same problem. Edited June 7, 2023 by JeffC 1 Quote Link to comment Share on other sites More sharing options...

I fixed 2 sets with the same problem. Hi JeffC, thanks for sharing, it's a big effort to investigate and create the document explaining in detail. I measured the MUTE Vs and I get 19.98v, I tested the C22 capacitor without removing it and it was not in short circuit, once removed it had 10.42 uF only. After replacing it my speakers are back to life. Edited July 3, 2023 by LuisG Repair completed Quote Link to comment Share on other sites More sharing options...
Razam Posted July 18, 2023 Share Posted July 18, 2023 Thank you for sharing this JeffC. I have one to repair but it was worked on previously. R48 and R12 are burnt. Can anyone share the values with me please? R12 looks like a 2R2 and R48 looks like 10R0, one of the large caps was replaced with a 6800uF... seems like a lower capacitance. A clear picture of the amplifier board would be excellent. Quote Link to comment Share on other sites More sharing options...
