Question about Altec Lansing Audio Players & Recorders

Open Question

I have a Altec Lansing ACS-45. I think the volume/power chip is bad. Old chip should be a PT2256, but I don't see it on my board. Could it be NE572N rather than PT2256?

SOURCE: Altec Lansing ATP3 volume control/power know gone bad

just sone it, i had to break a whole in the bottom part , work my way around it with a screwdriver , it will snap every 2-3 cm and come off in the end.
after its off start at the (now exposed) bottom of the front bit and work your way up and aroud `till it comes off. mind the wires . as for the volume button fix , as soon as i played with it and tried it again , everything was good. even though replacing it doesn`t seem like a big deal
put it back together and will superglue it in the future( while typing this i doubt if it will ever happen), and it lookes good( except from the bottom ,where its broken !).
now the button is solid and the sound as well.

My problem is when i turn up the volume of the speaker it will just turn off. tnx


Your altec lansing need to be open, because it has a loss connection on the power supply part of its circuit board. that is why when you turn up the volume it turns off because it produces vibration enough to shake the circuit board which has a loss connection.

1. Prepare the following tools:
* soldering gun/iron / soldering lead and a magnifying glass
* open your altec lansing cover enough to see the circuit board
2. Try to examine the leads on the circuit board, try to share some of the spare parts make sure it is not plug to live outlet to avoid electric shock.
3. if you see some spare parts shaking try to resolder it.
4. Then close back the cover.
5. Then test your altec lansing

Just want to know what it would cost to buy the altec lansing speaker moder acs 45.


It will cost you about $75 for the Altec Lansing ACS45.2 Powered Subwoofer Speaker, which I am assuming is what you're talking about, since the only thing that comes up under ACS45.2 is that. It should cost you about $75, although you will generally only find used ones because Altec Lansing no longer sells them.

This is a loose connection between PC and the Sub-woofer. The cables may damaged or it may be a hard ware problem.
