ATT Phone Model CL4940: Screen is lit, but remains blank

Cable modem:  ARRIS CM820A/NA


Router:  Linksys Ethernet/DSL Router with 4 port switch model BEFSR41


Phone Adapter for VOIP: Cisco 2 port phone adapter SPA112

 

Phone: CL4940 ATT

 

About a week ago I cleaned my ATT CLF940 phone with a slightly wet rag.  It stopped working for a bit, I turned it upside down for an hour, then all was well again.  A day later the screen went blank, and stayed blank.

 

I can make and receive call with no problems.

 

The phone makes sounds when I push the buttons, but nothing ever appears on the screen, even when I call the phone.

 

I tried unplugging the phone for 1 minute, then plugging it back in.

 

Is there anything else I can try?

 

Thanks

 

Steve

Try putting in in some drying agent (desiccant) overnight, rice will also work but not as well.

 

Edit: Remove the battery

I didn't see anything in the manual about the phone even having a battery.

 

How do I put dessicant inside of the phone?

 

The phone has had a week to dry out.

 

Thanks much for the ideas, not sure how to apply them.

You don't put the desiccant in the phone you put the phone in a container of desiccant.  You usually do this fairly soon after the phone has gotten wet, after a week the damage may be done, but you can still try.  Even though it's been a week there's more than likely still moisture in the phone. Since you have a full size phone it will take a lot of desiccant, so you may want to consider just getting a new phone. Just for future reference us alcohol to clean it instead of water as alcohol evaporates quickly.  The battery was just an, in case thing.

Thanks.

I thought I would give it one good try before giving up and getting a new
phone.

Thanks for the response.
