Open handset for KX-TGA571A

I am attempting to open the case of the handset to reset the keys to work properly. Unfortunately, I cannot seem to open the case. I have removed to two screws in the case but I do not know how to release the upper holding mechanism. I do not want to force it and break it as a result. How do you open the case of this phone, Panasonic KX-TGA571A. Thanks.

    OK, I solved my issue. After taking out the two screws from below the battery compartment, the case will separate slightly on the bottom. Take a screwdriver and carfully pry the case open along both sides, working from the bottom toward the top of the handset. This will free the back of the handset from the primary components. It will simply snap back together when done and then replace the two screws.

Keypad not working 1208

This is issue is quite common on most handsets, regardless of the manufacturer. What happens is that the handset will freeze up, and simply resetting the device will rectify the issue. The first thing that you will want to do is to make sure that the handset is on, and then remove the battery. This is called a hard shock and will reset the handset. Once you have removed the battery you will wait approximately 1-2 minutes and then reinstall the battery, then the cover and then you will power the handset on. Your keys should then be working, and if they are not, then you have something that is going on with the computer board in the device and it may be covered under warranty by the manufacturer if the device is under a year old. If this is the case, then you will want to call your cellular provider to file an insurance claim.

My Toshiba Satellite P105 touchpad and keyboard are not functioning. It almost seems that I have somehow locked or disabled it. I can plug in a USB mouse and get to my desktop to open progams and such but...

If only some aren;t working, attempt to clean it with compressed air (fter verifying that this is safe for your computer).

If all of the keys aren't working then most likely this is hardware related. Faulty wiring replacement should only be attempted by a professional (unfortunately).

The last thing that comes to mind is that someone spilled a liquid within your keys =P

Uniden TCX905 cCordess phone Handsets # 3 and 4

If the handsets are not currently registered to any base, the SYSTEM RESET menu won't appear.

If the TCX905 handsets in question are actually expansion handsets from another Uniden Phone System, they are not true TCX905 handsets. To verify, remove the battery cover and battery, then look at the inside label. If it lists the model of a TRU9xxx phone system, your handsets are NOT TCX905.

Uniden unfortunately has programmed the expansion handsets from SINGLE LINE TRU9xxx phone systems to NOT REGISTER against the TRU9466. (Those same handsets register fine against predecessor model TRU8866 though).

i think the keypad sensor is the problem ...
if your good at opening then just remove the handset take off the keypad check the keypad is it in good condition or not ..
if not you replace with the new one ...
& also clear if there is any obstacles in the keypad sensor ...
this will solve your problem .
it cant be the firmware problem so just do this it will be fixed ..
if you are not good at opening then just tap the phone lightly so that if there is any loose contact in the keypad with sensor it may get fixed .... otherwise you must & should open the handset & do it ...
if you are afraid then just visit the technician ...
it is just a matter of some bucks ... i think you can only do this simple thing by opening...

any doubts reply me
i am always here to assist you
thank you
