this brand still available in the market?

Just joined. Am currently working on same unit ACS45. Just got mine working with a new chip, but no volume control. Not sure if it is really any different than the 45.1.
Your issue is probably the volume control chip. I can walk you through the repairs in exchange for more detailed pics of the volume circuit. Please show how wires relate to plug. I have just the sub/ amp without the L/R speakers. Need to figure out the connections for the volume buttons.
I even have several spare volume chips if you need one.

Tengok ada spare parts x

Saya pun nak repair gak ni. Sebab setiap kali on fuse asyik blow je.

ATP3 owner here... in the process of replacing all the capacitors as preventative maintenance (and some old ones conked liao)

I have a ATP3 up for sale, mine is still functioning really well, are you interested ?

Guys I need some help here on my Altec Lansing ACS 45.1

I did fix it myself couple of years ago and I forgot the link on where was the guide of replacing the mosfet IC and sound controller.

So right now I’m not sure which IC need replacement as I’m facing sudden power cut off and buzzing sound.

I can’t recalled do I need to replace the ST electronic chip mounted in the large heat sink, as I didn’t replace the electronic volume controller chip Toshiba before as it didn’t give that problem.

Does it hum even when the audio cable is disconnected?

I've found the culprit. The big cap 10,000uf has worn off. That cause buzzing/humming sound.

Did you replace it with a high-quality-branded capacitor?

yeap

hi guys how do you dismantle the acs 45.1 satellite speaker
i take out the front dust cover , saw 4 holes at the 4 corners edge but they do not have any screw inside
only has 4 screw that are used to secure the pie shape shape cone

what were you planning to do? Cannot access the insides by removing the speaker?

its a pity the brand not doing speakers for pc anymore
they now more focus on headphones & portable/mini bluetooth speakers

HI, I'm looking for altec lansing ADA885 pristine condition. PM thanks

I have ATP3, and VS3251 up for sale, PM me if interested.

Can someone please show pictures of the ADA885 inner circuit board, i.e. thhe one below the sub-woofer speaker. Mine keeps cutting out and I have seen on other forums how it can be fixed by fresh soldering of a circuit. If you can post the schematic or pictures, I would appreciate it. Any info or tips on how to fix the sub-woofer cutting in and out would also be nice to have.
Thanks

Hi Guys,

I have an AL 321 type 2.1 speaker for about 18 years now. When I'm turning the volume button, the speaker gives a faint humming noise. I guess a squirt of contact spray would make wonders for the rheostat, but I don't see how could I disassemble the small speaker (in a reversible way of course). Any hint or idea?

Thanks a lot

I can only guess from google images but, do they have rubber feet underneath hiding the screws?
