This is not something that you will get access to from here. Try asking a repair shop if they can get the schematics for this speaker. You could also contact A-L directly.
Not likely to happen. Altec Lansing ACS340 Specs CNET
Furthermore these are inexpesive 2.1 speakers that can be replaced for 30-40 dollars. Not worth the effort.
The problem I have found is the contact glue between the back panel and circuit board inside the sub woofer. The glue becomes conductive after some time (2 years..!!) and needs to be scraped away from across tracks, you can tell the problem areas as the glue is pale yellow but goes brown and conductive over time. Good luck. Regards aj
yes, you can splice the cables and put on a new connector, goto radio shack with the old connector and im sure they will have one you can splice right onto it. ive done this many times with varios equipment "headphones speakers etc" it may take a couple of tries to get the wiring right but if its just one speaker there will most likely be just 2 wires, if you wire it up and it doesnt quite sound right, wire it the other way. speakers will work wired backwards but wont sound quit right so if it doesnt, rewire it and it should. good luck and i hope this helps!
The amps are 8-pin CHN 4558CN [K1D142]
and 8-pin PHIL TDA8199 [LD8136]
The Voltage Regulator is a 14-pin LM324N
There is a 3-pin LM7812CN 12-volt regulator...
They are in the sub-woofer housing which is held in place by tape so it can be pried off if done with care.
Hope this helps.
If you have all the cables and wires in place I would appreciate knowing the connection sequences (someone cut all the wiring to the set I have.)
there are fast checkings for you:
Quick Connect Card
is the system working fine exept the sub?
my guess: the headphone jack works fine then the speakears are too
if soo then the sub amp is bad
or some connection is torn
try opening the sub and see if everything is hooked right
and if soo then the amp is the problem
every electronics shop can fix this
