Question about Samsung SCH-A990 Cellular Phone
My phone recently went through the wash. I let it out to dry for a while, and now it will turn on and recieve calls like normal except for the fact that none of the keys work. What can I do? Is it worth it to keep the phone?
There may be a way to fix this, but this will certainly void the warranty, and should only be attempted by someone familiar with electronics. It may be possible to restore the conductive material (graphite lubricant, as I understand it) between the button and the electronics. If you can find someone who knows something about this, it might be worth a try; you can't break it much more than it already is. If you've let it dry completely and it still doesn't work, the only way to fix it is going to involve opening it up.

Tips for a great answer:
It may be an
issue with heater circuit, door switch or wash pump, please reset the power to
the dishwasher. After, 5 minutes check if you are still getting the same error.
If yes, then it is a water heating fault. To resolve this error try pressing
this reset sequence-- Heat Dry - Normal - Heat Dry - Normal or High Temp - Air
Dry - High Temp - Air Dry or Hi Temp Scrub, energy saver dry, Hi Temp Scrub,
energy saver dry. Now let the unit run for 2-3 minutes and then you press
the Cancel/Drain button and allow it to completely drain and reset. If this
doesn't work then it's an issue with the wash pump not pumping the water past
the heater efficiently or due to lack of water to heat. Please make sure that
heater is not open circuited and is heating the water efficiently. You'll have
to check the heater using a multimeter; the meter should read between 3000 to
3300 ohms (Use multimeter on Rx1 ohm setting). If heater is fine then make sure
water pressure is optimum and fill valve is working fine. Hope this helps...

Open the door. Within 3 seconds press the following sequence --Try pressing normal wash, heated dry, normal wash, heated dry, normal wash, heated dry three times within 6 seconds and then press cancel to reset the dishwasher. If that doesn't help then try pressing Saini Rinse, Heated Dry, Saini Rinse, Heated Dry, Saini Rinse, Heated Dry or Saini Rinse, Air Dry, Saini Rinse, Air Dry,Saini Rinse, Air Dry 3 times in 6 seconds and then the Cancel Button. Close the door and press Cancel.
Blinking lights would stop and should be able to use your dishwasher normally. If the light is still blinking try and reset the power to the dishwasher and try again. If still the light is blinking then check for the connections on the keypad, it may be due to moisture or shorted connections on keypad.
Hope this helps... Please post back if you need more information.
