Hi, If all else fails, try do a hard reset. You can verify from your manual, but in some units, this is merely unplugging the unit from mains for a couple of hours. Try again, if it still shows error codes (blinking lights) you probably have to seek the services of a qualified professional. Hope this be of some help/idea. Good luck and kind regards.

I may not be of much help but I may be able to guide you into some diagnosos. If there is a communication problem between the inside and outside unit, both on the inside and outside units a colored LED will bling 5 times then pause for 3 seconds. The 33 and 44 codes are confusing to me because I have never seen this. Try resetting the outside unit with no call for heat or cool from the inside unit. After about 20 seconds, restore power to the outside unit. Go in and turn on the remote and make sure you lower the cool setting more than degrees cooler than the room temp. After 3 minutes the outside unit should turn on. If you get an error code of either 1, 2 or 5 blinks document it for the technician. If you continue to get your 33 and 44, you have a bad control board. If all else fails, press and hold the button located on the lower left side of the art unit and hold for about 5 seconds. If it still no longer works, now you will need the help of someone who knows these units.

Strange noise comes out from the ups after a power cut


The Back-UPS Office unit has five different tones or alarms:

1. Four beeps every 30 seconds (On Battery LED will be illuminated)
This alarm indicates that the Battery Power Supplied outlets are now supplying battery power as opposed to power from the utility. If the UPS determines that the input utility power is unsafe for your computer equipment, the UPS will switch to battery power.
Note: If the power disturbance is brief, you may only hear one or two beeps.

2. Continuous Beeping (On Battery LED will be illuminated)
This alarm indicates that a Low Battery condition has been reached and that the UPS will soon shutdown. Once the UPS transfers to On Battery operation, it can only stay on battery for a limited amount of time. The UPS will sound this alarm about two minutes before the batteries are totally exhausted. Once exhausted, the UPS will shutdown and turn off its output power to your equipment. If you hear this tone you should immediately shutdown your computer to prevent data loss or corruption.

3. Continuous Beeps for 30 seconds (Back UPS OFFICE 250 and 280 ONLY)
This alarm indicates the unit has detected an Overload condition after it has performed a self-test during start-up.

4. Continuous Two-Tone Beep
This alarm indicates a severe Overload was detected while the unit was on-battery operation. This tone will continue to sound until the unit shuts down.

5. Continuous Tone (On Battery LED will be flashing)
This alarm indicates that the battery-powered outlets are overloaded.

6. Continuous Tone (On Line and On Battery LEDs flashing) Back UPS OFFICE 350, 400, and 500 ONLY
This alarm indicates that an internal UPS fault has occurred.

My Panasonic PT-60Dl54J tv shut itself off and the power button is now flashing red 6 times. What has happened, how do I fix it?


This is straight from the service manual (I'm not sure what the problem is but it sounds serious):

8.2. Power LED Flashing timing table
When an abnormality has occurred, the protection circuit operate and cuts the power supply. At this time, the defective line can be
identified by the number of flashes (red) of the power led indication at the front of the unit.
NUMBER OF FLASHES CIRCUIT MICRO PIN
1 LOAD SHORTAGE 92
2 OVER VOLAGE 93
3 FAN SOS 94
4 MAIN 3.3V 88
5 LAMP DISABLE 61
6 GC3FM-IIC IIC
7 GC3FS-IIC IIC
8 GC3I-IIC IIC
9 COLOR WHEEL STOP 110

I have a digistat scr with a flashing red light and no heating there is nothing wrong with the batteries, this only occured after a poweer cut.


Try this first before condeming the unit.

1. Turn off the power supply to the Digistat SCR (receiver unit)
and leave for 5 seconds.
2. Turn on power to SCR unit and check red light is on.
3. Press override button No.2 and check the green light comes
on and boiler fires.
4. Press & hold down button No.1 (Keep depressed), then
press No.2 and keep depressed. {The Red LED light will flash
a couple of times and then it will go out}
5. Now release both the buttons – {the two LED lights should
come back on}
6. Get the Digistat+2RF/+3RF unit and stand two metres away
from the SCR unit with the Digistat+2RF/+3RF unit in your hand.
7. Remove the battery cover and fit the batteries.
8. The Red LED light on the SCR will now flash for approx. 7
seconds.
9. This confirms that the radio signal is being sent and
received.
10. The Digistat+2RF/+3RF and the SCR are now successfully
linked by a dedicated RF address.

Here is the proceedure to replace the lamp and reset the lamp hours.
Lamp Replacement Procedure:
1. Press the POWER button to turn off the power.
2. Wait for about 1 minute until the cooling fan stops.
Note:
The lamp cooling fan will continue to operate for about 1

power strips.
3. After the cooling fan has stopped, unplug the AC Cord from

Note:
Please wait more than one hour before replacing the lamp.

After the POWER button is turned OFF, and during the
first minute of the normal cooling fan operation, press
the VOLUME UP button on the unit and CH UP key on
the remote at the same time for more than 5 seconds.
The cooling fan operates for about 10 minutes. (LAMP

4. Remove the Front Cover Unit from the latches.
5. Turn the Knob to the left.
6. Pull the Lamp Cover out.
7. Loosen the Screw on the Lamp. Then, pull the Lamp.

Because the Lamp may still be hot, use caution when

10. Install the Front Cover Unit.
Lamp Time Reset Procedure:

Lamp.
1. Plug in the AC Cord, and turn on the power by pressing the
POWER button.
2. Press and hold the VOLUME DOWN button on the unit and
the SPLIT key on the remote together for over 5 seconds
in power on condition.
When the reset is finished, the display will indicate that the lamp hrs have been reset to 0 and the LAMP LED goes out.

Dead Creative Zen M


Usually this problem is due to the firmware. When the firmware is updated to version 1.62.02, this problem usually will be corrected. The older firmwares have problems in recognizing the battery and allowing the battery to power the unit.

You will need a wall/AC charger for the operation. Plug in the wall charger and USB cable at the same time. Your Zen should power on when connected to direct AC power via the wall charger. Once it is powered on, connect the USB cable to your computer. Then begin the firmware download.

If your Zen does not power on when connected to the wall charger, your unit is dead and its time to replace it or get the motherboard replaced via one of the Repair services offered on this website.

If the upgrade button on the firmware window is not available, it is also time to replace your motherboard due to corruption of a chip on the board.
