My indesit washing machine 12 hundred keeps flashing blue and red lights and won't do anything


Possible that the suspect could be the controller board, you can switch the machine off power for sometime, check the power outlet for the correct voltage. If not the front panel must be removed to check on the board and a possible fault of the processor or memory.

Why wont my logitech boombox go into bluetooth search mode


I had the exact same problem. Boombox flashing blue, but not rapidly flashing blue. I did two things that seemed to fix it:

1: Reset the device by switching it on, then holding both volume up and volume down buttons at the same time for 10 seconds. The blue flashing light will briefly flash quicker to confirm.

2: Switch off the boom box

3: Switch on using the power button and (very important) immediately press and hold the Bluetooth button. The Bluetooth button needed pressing and holding almost instantaniously after the power button for it to work for me. I had to try several times to get it to work.

When you do this successfully, the Bluetooth light starts flashing rapidly and it enters search mode.

I nearly threw my speakers away, now it works and connects fine :)

It wont turn on just flashed red light and wont give the disk back


watch the lights on the front when you try to turn it on. If the blue light flashes yellow for a second, you have ahardware failure, so-called Yellow Light of Death. You can get the disc out by turning off the switch at the back, then hold down the eject button and turn the back button on again.

Can't get rid of "LINE IN USE"


I have repair some cordless phone a lot with your same problem .Your Handset is encountering a left over switch on your buttons what i mean is that the switching is logged. do some cleaning on the carbonized switch of the handset . check if there is moist assembling on switches if none try to clean the carbonized switch and keypad with alcohol cotton buds try also to swipe out the worn out carbon on the switch. if these wont help . your handset might have component damage already like an IC defect . that is why your phone wont work . It is best to bring you phone to the manufacturers service shop.
