Hello all,
Last week I discovered my 4.1s weren't working (no sound, LED not
lighting up). After scouring the forums and calling Klipcsh a few
times, I found that the 3 main causes are:
1) Bad Fuse
2) R26 dead
3) R12 dead
So, I did the following:
1) Although the fuse was still in tact, I replaced it anyhow. I plug in
the sub, and I can hear the high-pitched "power" sound, the multimeter
shows the fuse is working, and the resistors are hot. Ok it is not the
fuse.
2) After going to several electronic stores that did not carry 56K 1
watt resistors, I ordered some off Ebay. Per the advice of this board,
today I replaced the R26 with the 56K 1 watt resistor, even though the
old one read ~50-51K. Still nothing. Ok it is not R26
3) I have not replaced R12, but I am getting a reading of around 625
(resistor still on the board), so I presume R12 is in good working
condition. Is this safe to assume?
After talking to Klipsch support, they wondered if the cable running
from the control pod to the sub was broken. Well I tested each pin and
every pin works. There is no power coming from the sub.
The only thing I couldn't really test today was whatever is under that
big metal encasing along the bottom of the sub (it connects to the
satellites and the control pod). Does anyone have any suggestions on
what to test next?
Craftsmen, you seem pretty on top of things here, do you have any idea what to try next?
Thanks!
