I have intermittency problem with my ATP3. I didnt know if it was because of the power switch that goes with the volume knob or a problem with the power suppply. What i did is to check on the supplies. i think its doin OK (output of the regulator is 9V) but it goes too hot.tried to remove the 7809 and measure the load for the 7809 and it read 50 ohms. is this normal? with the instruments that i have, I cant further isolate where the problem really is. cant opent the left satellire spkr. anyone who knows how to solve this?
I've had intermittent speaker problems with these models and it was caused by slight abuse, ( stress on the speaker jacks at the main board located in the main subwoofer cabinet). The problem can lead you to believe its the speakers or the wires but in my case it was a loose solder joint on the main board in the subwoofer. I had to take the subwoofer apart and carefully re-solder the connections of the speaker jacks. I've had no problems since. I've also been a little more careful not to push the jack side of the connection against the wall, kicking with my feet etc..

What specific problem are you having? Some have reported that squirting tuner cleaner into the back of the switch/ volume control will clear up some intermittent conditions. If the on/off switch on the back is defective you can jumper it to leave on full time but then you'd have to use a power strip or similar to turh it off.
you could have blown an internal fuse depending on the power options and how long and high you had them. The definate way to know is to try them on another computer. To they turn on at all or is there just no sound. If they turn on, jus without sound then you may have blown a speaker but if the don;t even turn on then maybe you blew a fuse. Either way the damage is not really fixable. Also, did you check your device? The power (volume) may not be high enough on the device. If using a computer then goto volume control and check each setting on the pannel for mute, balance options and most importantly, volume. One seemingly unimportant seeting could be the difference between hearing and not hearing your valuable system beeps and music.
hi i used to have the same problem opening the satellite speakers of atp3 (left satellite, the cord was pulled and snap from the inside). i found out how to open them but there's a good and bad news. the good news is i know how to open them, the bad news is that it will cause some damage on your satellite speaker.a friend of mine used to have the same speaker he accidentally drop one of his satellite speaker (left one) and the bottom cover just crack open following the joint line. the satellite speakers of atp3 has no connecting screws , it is assembled using a sort of super glue. here is how i opened my satellite speaker. i used a flat screw driver (i sharpened it a bit to easily penetrate the joint) to shove the bottom cover of the speaker starting from the back part (near the cord) then slowly made my way around when the cover start to snap from where i started. you can remove the bottom cover this way but be aware that it will cause some damage on you speaker. i started shoving from the bottom back part because the damage is unnoticed when you reassemble it using a super glue and i use a black paint to hide the discolored plastic casing cause by force opening.
