Display blank but sounds and blinking light

I've got this ALCATEL 5015A Pixi 3 (5) 3G phone, which was dropped in something wet. Don't ask what, I can only assume it was a shallow puddle.

When I take the battery out, and put it back in, the (white) led on the top right corner lights up.

When I push the power button I can hear the 'logo jingle' you get on some phones.

After that, I get a regular 'tone' 15-30 seconds apart.

Yes, it has a SIM card in it. No, there isn't even the slightest of light coming from the display assembly other then the 'status' light.

I even left it unplugged for over a week (two?) and the light remains on after removing the battery and putting it back in.

Hi,

As you know water and electronics and electricity are not a good mix.

The water causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components.

First do not turn on your phone and then you need to remove the battery as soon as possible from the phone to minimize further damage.''

Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 90%+ to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% and is not as effective. If you do check the label to verify the amount

Here is a link that in general, describes the process.

Electronics Water Damage

You will probably have to replace the battery as it is very hard to recover a battery from water damage.

As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board.

Hopefully after you have done all this the phone might possibly work correctly again.

Here is a link that shows how to dis-assemble your phone.

If you decide to do this, do it sooner than later.

I've been hunting the LCD for this and it seems it's hard to get. I hope none of the electronics inside need replacing. The (5) of this model especially.

I'll likely attempt a tear down and clean this weekend.
