Question about Sony Ericsson K800i Cellular Phone

1 Answer

Keypad and joytick problem

From time to time my joystick does not react on "left" and "down" and at the same time both buttons left of the joystick do not work ("Select" and "Return") as well as numbers 1 and 7.

Then some time later (in few hour or few days) everything works fine again until the problem reappears.

Strangest thing is that even when joystick is not working ( left and down) in any menu or start screen, it still responds fine for scrolling down sms messages that are longer than one screen.

Can you please tell me shat is the problem?

Z525a screen comes on but stays vacant.

If you have access to a laptop computer that has an Infrared Port or Bluetooth communications, you can download your videos and picture files via either of these two methods. I use an old IBM Thinkpad 600 with IR port to download mine. You have to put your z525 phone into Infrared mode first, its kind of tricky with out seeing what you are doing. First, open your phone, press upper right (-) sign to get menu, click joystick control down 2 times then right 1 time. next press upper left (-) sign to select. next joystick right 4 times, and down 1 time. press upper left (-) sign, then joystick up 1 time. press upper left (-) 1 time. Your Infrared Port will now be turned on, and your I.R. enabled laptop can now receive the files from your phone. Close your phone, open it again, press upper right (-) , press joystick down 1 time, then left 1 time, then press the joystick center select button 2 times. Joystick right 1 time, press joystick select 1 time. press upper right (-) 1 time, joystick down 5 times, joystick right 1 time, joystick down 3 times, joystick center select 1 time. Hold the lower left corner of your phone toward the I.R. port of the laptop, it will receive the first photo file in your camera pictures file. Another possible method would be to obtain a usb connector cable for the z525 phone to connect it to your computer. Using the usb cable the computer would recognize the phone, you could click on the phone icon, under "MyComputer" and transfer the files to your hard drive. I hope this helps. -Mike

Setup wizard

First open your phone, then press upper right (-) key to get to menu. press joystick down 2 times, then right 1 time, to get to Settings. Press joystick center select button, press joystick down 9 times to get to Master Reset, press center select button. Joystick down 1 time to get Reset Device, press center select, then press upper left (-) key. This will delete all user settings & data, including pictures, messages, data, sounds, games, contacts etc. The phone will be restarted. If this doesn't fix the problem, you will most likely need to replace the internal wiring harness.(Not a job even I would enjoy!) Hope this helps.
