How to Troubleshoot a Palm 700W

If you've been having hardware issues with your Treo handheld recently, chances are the problem is either the screen or the power source. Software issues can often be resolved by resetting the device, but if you're plagued by horizontal lines on the screen or the unit simply won't turn on, then the issue is likely either a faulty screen connection or a bad battery. The battery can be replaced in no time at all, but to fix a screen problem you will need to disassemble the unit.

• 1

  Turn the unit off, turn it over and slide the battery door down and off of the unit. Remove the battery and set it aside.

• 2

  Remove the seven screws on the corners and sides of the rear of the device. The screw underneath the antenna is covered by a rubber pad. Use the tip of your screwdriver to pop the rubber pad off and set it aside.

• 3

  Remove the antenna and set it aside.

• 4

  Insert the tip of your case opener tool in the seam between the front and back halves of the unit. A case opener tool is a thin plastic prying tool designed for opening electronic devices and is available at most electronics stores. Work your way around until the two halves separate. Set the back half aside. The motherboard will be visible in the front half.

• 5

  Locate one of the orange screen cables connected to the left side of the circuit board. Check to make sure it is secure. If it isn't, unplug it from its port and plug it back in, making sure it is secure. If this doesn't fix your screen problem, proceed to the next step.

• 6

  Slide the motherboard out of the front housing. The LCD screen will be connected to the underside of the board.

• 7

  Lift the LCD screen from its side to expose the remaining orange screen cable connected to a port on the underside of the board. Check to make sure the connection is secure. If it isn't, unplug it and plug it back in. If the problem isn't fixed you can unplug both screen cables, remove the screen completely and replace it with a new screen. From there reverse the steps for reassembly.
