Power light flashing green and amber - Polk Audio PSW Series PSW125 Powered Subwoofer

from the web -
1 Removed the battery
2 Removed the AC power
3 Plugged in the AC power again
Note:- At this point the light from flashing amber light to solid green indicating AC Power
4 Plugged in the Battery
Note:- Solid green AC power light and Amber charge light

my power light flashes green/ amber as soon as it is plugged in, with a dead battery. It seems to go to steady amber if the plug is tapped, but goes back to flashing. It will not hold a charge on a new battery.

change/clean manually the main roller because it observe ink.

when i turn the printer on the light flashes amber several times, then green then repeats flashing amber, and back to green etc. turning it off and back on made no difference. last time it worked normally after being off for a couple of days, but now it is doing that again.

Amber light flashes 7 times, then green for a couple of seconds, then amber 7 times etc.

what error message coming from your computer...i think something stuck inside your printer

sounds to me like it isn't receiving a signal and stuck in power saving mode, i would recommend trying another computer that you know is outputting a signal and go from there. if that doesn't work then my guess is its broken.

4 blinks of the amber light says that the ink is empty, at least 1 cartridge is empty.

this is most likely the sustainer board(s) problem. Replacing the sustainer boards should correct this problem for you. you can get the parts at vancebaldwin.com

The diagnostic procedures from the Dell User Guide are as follows:

Total Power Failure When Using a Battery
If an AC adapter is not connected to your computer, the computer's power source
is a battery. If the battery indicator flashes amber or is a steady amber, the
battery needs to be charged. If the battery is flashing green and amber, the
battery may be defective. To troubleshoot this problem, use the following
procedure.
1. Turn off the computer and peripherals, and disconnect them from AC power.
2. Reseat each installed battery by removing it and then replacing it.
3. Turn on the computer. Does the green power indicator light up?
Allow one minute for the computer to initialize its components before checking
for signs of power.
Yes. Continue to step 4.
No. Use the AC adapter to connect your computer to AC power. If the computer
operates normally when using AC power, go to step 7. If the computer does not
boot when using the AC adapter, see the previous subsection, "Total Power
Failure When Using the AC Adapter."
4. Does the battery indicator flash amber or show a a steady amber light?
Yes. The battery needs to be charged. Go step 5.
No. Go to step 7.
5. Connect the computer to AC power, and fully charge the battery.
For instructions, see the topic titled "Charging the Battery" in the online
System User's Guide.
6. As the battery charges, does the green battery indicator light up?
Yes. Go to step 9.
No. Go to step 7.
7. Is the battery indicator flashing green and amber?
Yes. Your computer may be in a hot environment. Charging the battery in this
condition may affect the life span of the battery. Continue to step 8.
No. The problem is resolved.
8. Disconnect the computer from AC power. Is the the battery indicator still
flashing amber?
Yes. You may have a defective battery. Continue to step 9.
No. The problem is resolved.
9. Remove the battery, and press its test button. Is the uppermost indicator in
the charge gauge of the battery flashing?
Yes. You have a defective battery. Continue to step 9.
No. The problem is resolved.
10. If a spare battery is available, fully charge it, and then install it in the
computer.
11. Turn on the computer. Is the power indicator off?
Yes. Your original battery is defective


good luck

I believe that 7 amber flashes refer to a cartridge error. Check that the cartridge is seated correctly.
