First thing I would check is the power supply, easiest way to test it is to just swap the power supply with a working one.

That's easier said than done if you're just an average user so unless you've got an extra power supply handy then I would suggest finding a local computer repair shop that provides FREE DIAGNOSTICS, most do these days. Have them check out the system. It's either the power supply or motherboard. HOPEFULLY it's just the power supply though ;)

If the repair shop says it is the power supply I'd sincerely thank them for their time (5 minutes) and then I'd buy a replacement power supply and install myself ($15-25)

Hope this info helps!

I have a Phillips dcm5090/10 sound tower when I switch the power on at the plug the unit wont switch on. I know power is getting to the unit because the blue light above the cd unit flashes. I have missed...


I have exactly the same problem. One morning a couple of days ago the DCM5090 simply wasn't possible to turn on. The blue lamp at the from shines - indicating that there is nothing wrong with the power supply - but pressing the ON-button has no effect. The display is unlit. Also the charging of an iPad I usually have connected on top no longer works.

Any thoughts? Broken fuse?

Power blue light flashing when i turn the computer on


It depends on where the blue light is. Is the blue light on the monitor or on the computer tower? If it is on the monitor the monitor is having problems and needs to be serviced. If it is on the tower it could be an issue with the power supply.

Bluetooth wont charge or power on. when charging the red light comes on. once disconnected from charger it wont come on


Indicator Lights:
1.Headset Status Headset Indicator Light
2.Powering on Steady blue, then intermittent flashes
(changes to standby mode)
3.Powering off Red appears and goes off
4.Standby Blue intermittent flashes
5.Charging battery Red solid light. Light indicator turns off when
battery is fully charged and headset is off.
6.Low battery Triple red flashes
7.Pairing mode Blue/red alternating flashes
8.Missed call Purple flashes. Press the call control button
to cancel flashing light.
9.Incoming call Triple blue flashes when ringing.
Power on and off:
1.Turn on the headset Press and hold the call control button until the
indicator glows blue. You will hear ascending
tones.
2.Turn off the headset Press and hold the call control button until the
indicator glows red. You will hear descending
tones. When power is off, indicator stays off.
If none of this is helpful then it may be that your battery is dead, if that is the case then you will need to replace the whole headset. The battery's are not replaceable.

Good luck from Headsets Direct!

Can not connect


Power up headset. Press and hold the + and - Volume buttons until the red and blue lights flash . Your phone should now pair with the headset. For passcode I used 1234 and this worked.
