Sometimes when the printhead goes bad, it keeps the printer from turning on. Try removing the inks and printhead and turn on. If it comes on, replace the printhead with a new one and don't put the bad one back in. The printhead is QY6-0049-000 about $50.00

Electrolux EXD15DN3W dehumidifier has power to unit, but wont start operation? Display is off, on button doesnt respond, but LEDs light and beeps when bucket is removed. Any advice much appreciated.


The bucket interlock may be defective. It works correctly to signal when the bucket is removed but doesn't signal the power switch that the bucket is in place.

Why has my mouse stopped working, also the touch pad on computer has stopped?????


Janice, This is info from Tomsguide.com
1- Turn off computer, disconnect the power cord, remove the battery.
2- Press the Power On button for 10 seconds
3- Replace battery and/or connect power cord.
4- Turn On computer + immediately press F2 key repeatedly
5- Press F9 then press Enter
6- Press F10 then press Enter
May have virus or corrupt driver, run your anti virus and try reloading divers for mouse and touch pad, you may have to use system restore to an earlier date when thins were working OK.
Check the attached links,instruction and guides, Good luck

Check all the fuses to see if they are blown and replace them. If not the case then you will have to take it to a repair shop. Check for loose wires under the hood. Be careful when doing so, so that you don't get electrocuted .

I have a whirlpool DU943PWKQU, first about 6 months ago all the push buttons except light wash stopped working. Now this week it started giving me problems starting all together at first I resolved by...


It seems to be the program controller and you will have to get this checked. Remove the power off for some time and reset it back . If the programs are not responding then you will need to check from the power cord to the control panel to see if this is working and can give hte output with the required inputs when the program is selected.
So does the water go in , if not the controller is faulty.

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope it may help you;


Regards;

Battery is dead


Identical problem - working only with power cord.
Wont power on battery or usb cable.

I actually opened player and check every single option.
(I am experienced electronic - tech.)
Result: battery is fully charged (768 mA/ 3.97V on bench)
Battery switch on bottom fully functional. (switching on/off 3.97V
comming from battery)
USB supply 5.0 V in perfect order.
Conclusion:
There is no "EASY" fix for this problem.
It is either problem with firmware (low possibility)
or semiconductor on logic board (practically not fixable on DIY basis)

I bought my Gigabeat 60Gb for $ 70.00 used on Ebay so
I will live with this problem.
