Yeah, the LCD screen of your handset model has a problem causing black lines to appear. Kindly bring it to service center to avail of the warranty if it still have.. :)
or to a cellphone technician who replaces LCD screen..
Have a nice day ahead! ^_^
You've got the split-screen turned on. To turn it off, press MODE to open the mode screen. Use the arrow-keys to move to the second-to-the-last line, highlight "FULL," and press ENTER. Press 2ND [QUIT] to exit the mode screen.
Batteries: Make sure to replace the "battery backup" too the little lithium ion battery
Try Adjusting contrast:
Hold down "[2nd]" key press up or down arrow repeatedly to lighten or darken contrast.
First attempt reseting: Step 1: Remove all the batteries Step 2: Hold "Clear" key down Step 3: Still holding "Clear" key reinstall batteries Step 4: Still holding "Clear" key press "On" key until home screen is displayed.
Second shot reseting: remove all batteries including lithium ion (backup battery), wait 3 hours and reinstall batteries.
Third Shot reseting:
Step 1: Remove a battery
Step 2: Hold down "DEL" key reinstall battery
Step 3: Possible msg pops up saying "Waiting ... Please install software" IGNORE msg and take out battery again Step 4: Reinstall battery do not hold down "DEL" key
reseting will cause the handheld to loose all of its stored memory.
I've had the same problem. A temporary fix that I have found is to turn up the contrast all the way (press [2nd] then hold down the up arrow) until the screen becomes mostly black. Then turn the contrast back down (press [2nd] then hold down the down arrow) until it is at a normal level. If you can get rid of all the white lines when you turn up the contrast the screen will be back to normal. Unfortunately this does not permanently fix the problem because I cannot get rid of all the lines and it seems to be getting progressively worse each time it start up the calculator.
