    two flashes and a pause indicate that there is a power line problem.
    this means that the voltage supplied to the A/C cord is out of limits. This happens at times when using a portable generator etc. The condition is a temporary condition and should reset itself.
    Try unplugging and then reconnecting to a known a/c 120volt outlet and see if the condition repeats itself.

There should be a diagram on the front right hand side of the charger that tells what each flash rate means.

The red light keeps blinking while I have the charger plugged in, is this normal?


Hi! If the light on the charger is blinking this can mean an issue with your charger adaptor. Check that the charger is still warm. If so, unplug the charger for a few minutes and plug it back in. If the light is still blinking your charger adaptor may need to be replaced. Hope this helps!

The sky remote will not operate the volume on my grundig gu22dvd have tried all the usual things codes etc but still doesnt work


Try an auto search with the remote, you might have already tried it :

1. press tv

2. press select and the red button simultaneously untill the LED light flashes twice

3. Then keep pressing the TV and Standby buttons one after the other (not at same time) until the tv swithches off, then press select to store the code, the LED should flash twice to confirm this.


Once you have the remote working the TV, you can get the remote blink back the TV code so you can write it down for future reference.

  • Press the TV button on the Sky remote
  • Hold down Select and the Red buttons together for approximately two seconds until the LED blinks twice
  • Key in 9, 9, 0
  • Key in 1 on the numeric keypad and count the number of times the Red LED blinks. This is the 1st digit.
  • Repeat for 2 and 3
  • Note: no Blink = 0 (zero)

Red light flashing on charger


A red light indicates the charger is charging the battery, an amber light means it has switched from fast rate charging to trickle to keep the battery topped off, and green would mean the battery is completely charged. But don't be fooled waiting for green, many times the charger will only be on green for a moment before changing to amber and keeping the battery topped off.

Flashing can be a sign of a problem on some chargers.

A rapid flashing red can on some chargers indicate a bad or shorted battery, or a bad battery contact in the charger itself. If in question, try a different battery on the charger or compare with another charger to determine if the blinking is normal.

Best regards.

Xperia u dont turn on just red led blinking after charge up


I experienced the very same problem twice.
The red led would either stayed on all the time when charger was connected or it blink whenever I'd push the power button on the phone, but the phone would not turn on.
My solution was to unplug the charger, take out the battery and the sim, keep them separated for at least 48-72 hours, then put back the battery, connect the charger again (don't use your computer's usb port, use a real wall charger, preferably the original one), turn on the phone.
If it doesn't turn on immediately, let it charge for a few hours and then try to turn it on.
I revived this phone twice using this method, first time I thought I was just lucky, but apparently it's reproducible.

Hope it works for you too.

1. Press the "DVD/VCR" button on the remote.
2. Press and hold the "SET" button on the remote until the red LED blinks twice, then release the button.
3. Enter the 4 digit code for the VCR. (Red LED should blink twice after you enter the code.)
4. Aim the remote at the VCR and press power. The VCR should turn on. If not, try another code until you find the right one.

dismiss all messages/notifications (for NO Blinking amber light), disable vibrate
attach the original charger, keep phone on a flat surface, find optimum position where the amber light is continuous.
repeat same if you answer any calls or move the phone
